abstract = {Objective Demonstrate implementation, safety and feasibility of multimodal, impairment-based physical therapy (PT) combining vestibular/oculomotor and cervical rehabilitation with sub-symptom threshold exercise for the treatment of patients with post-concussion syndrome (PCS). Setting University hospital outpatient sports medicine facility. Participants Twenty-five patients (12\textendash20 years old) meeting World Health Organization criteria for PCS following sport-related concussion referred for supervised PT consisting of sub-symptom cardiovascular exercise, vestibular/oculomotor and cervical spine rehabilitation. Design Retrospective cohort. Main measures Post-Concussion Symptom Scale (PCSS) total score, maximum symptom-free heart rate (SFHR) during graded exercise testing (GXT), GXT duration, balance error scoring system (BESS) score, and number of adverse events. Results Patients demonstrated a statistically significant decreasing trend (p \< 0.01) for total PCSS scores (pre-PT M = 18.2 (SD = 14.2), post-PT M = 9.1 (SD = 10.8), n = 25). Maximum SFHR achieved on GXT increased 23% (p \< 0.01, n = 14), and BESS errors decreased 52% (p \< 0.01, n = 13). Two patients reported mild symptom exacerbation with aerobic exercise at home, attenuated by adjustment of the home exercise program. Conclusions Multimodal, impairment-based PT is safe and associated with diminishing PCS symptoms. This establishes feasibility for future clinical trials to determine viable treatment approaches to reduce symptoms and improve function while avoiding negative repercussions of physical inactivity and premature return to full activity. © 2016 Elsevier Ltd},

abstract = {Background: Concussions are a common pathology in football and multiple misconceptions exist amongst the players and managers. To address these misconceptions, and potentially reduce concussion associated sequela, effective educational interventions need to be developed. However, the current knowledge and attitude status must be ascertained to appropriately develop these interventions. The purpose of this study was to assess the concussion knowledge and attitude of English professional footballers. Methods: Twenty-six participants from one English Football League Championship club completed the study. A mixed methods approach included the Rosenbaum Concussion Knowledge and Attitudes Survey (RoCKAS) and a semi-structured interview. The RoCKAS contains separate knowledge (0-25) and attitude (15-75) scores and was followed by a semi-structured interview consisting of concussion knowledge, attitude, and behavior related questions. Results: The mean score on the RoCKAS knowledge was 16.4 ± 2.9 (range 11-22) and the attitude score was 59.6 ± 8.5 (range 41-71). The interview responses identified inconsistencies between the RoCKAS and the intended behaviors, endorsing multiple concussion misconceptions, and revealed barriers to concussion reporting. Conclusion: The results of this study suggest that Championship Level English footballers have moderate concussion knowledge, safe attitudes, and good concussion symptom recognition when assessed with pen and paper questionnaires. However, within the semi-structured interview many respondents reported unsafe concussion behaviors despite accurately identifying the potential risks. Further, multiple barriers to concussion reporting were identified which included perceived severity of the injury, game situations, and the substitution rule. These findings can help form the foundation of educational interventions to potentially improve concussion reporting behaviors amongst professional footballers. © 2016.},

abstract = {A concussion results from a force to the brain that results in a transient loss of connectivity within the brain. Sport psychiatrists are increasingly called to be part of the concussion team and need to be prepared to manage issues related to concussion and its behavioural sequelae. Objectively, the best evidence available suggests that deficits in attention and/or in balance are the most reliable objective findings that a concussion has occurred. Prognosis after a concussion is generally very good, although a sub-set of patients that are yet well defined seem pre-disposed to delayed recovery. Neither head CT nor MRI are sufficiently sensitive to diagnose the type of injuries that pre-dispose patients to the neurobehavioural sequelae that have been associated with a concussion; confounding this is the finding that many of these signs and symptoms associated with concussion occur in other types of non-head injuries. Brain biomarkers and functional MRI (fMRI) hold promise in both diagnosis and prognosis of concussion, but are still research tools without validated clinical utility at this time. Finally, neurocognitive testing holds promise as a diagnostic criterion to demonstrate injury but, unfortunately, these tests are also limited in their prognostic utility and are of limited value. © 2016 Institute of Psychiatry and John Hopkins University.},

abstract = {Background: Concussions have been associated with elevated musculoskeletal injury risk; however, the influence of unreported and unrecognized concussions has not been investigated. Hypothesis: The purpose of this study was to examine the association between concussion and lower extremity musculoskeletal injury rates across a diverse array of sports among collegiate student-athletes at the conclusion of their athletic career. The hypothesis was that there will be a positive association between athletes who reported a history of concussions and higher rates of lower extremity injuries. Study Design: Cross-sectional study. Level of Evidence: Level 3. Methods: Student-athletes (N = 335; 62.1% women; mean age, 21.2 ± 1.4 years) from 13 sports completed a reliable injury history questionnaire. Respondents indicated the total number of reported, unreported, and potentially unrecognized concussions as well as lower extremity injuries including ankle sprains, knee injuries, and muscle strains. Chi-square analyses were performed to identify the association between concussion and lower extremity injuries. Results: There were significant associations between concussion and lateral ankle sprain (P = 0.012), knee injury (P = 0.002), and lower extremity muscle strain (P = 0.031). There were also significant associations between reported concussions and knee injury (P = 0.003), unreported concussions and knee injury (P = 0.002), and unrecognized concussions and lateral ankle sprain (P = 0.001) and lower extremity muscle strains (P = 0.006), with odds ratios ranging from 1.6 to 2.9. Conclusion: There was a positive association between concussion history and lower extremity injuries (odds ratios, 1.6-2.9 elevated risk) among student-athletes at the conclusion of their intercollegiate athletic careers. Clinical Relevance: Clinicians should be aware of these elevated risks when making return-to-participation decisions and should incorporate injury prevention protocols. © 2016, © 2016 The Author(s).},

abstract = {As participation in women’s soccer continues to grow and the longevity of female athletes’ careers continues to increase, prevention and care for mTBI in women’s soccer has become a major concern for female athletes since the long-term risks associated with a history of mTBI are well documented. Among women’s sports, soccer exhibits among the highest concussion rates, on par with those of men’s football at the collegiate level. Head impact monitoring technology has revealed that 'concussive hits' occurring directly before symptomatic injury are not predictive of mTBI, suggesting that the cumulative effect of repetitive head impacts experienced by collision sport athletes should be assessed. Neuroimaging biomarkers have proven to be valuable in detecting brain changes that occur before neurocognitive symptoms in collision sport athletes. Quantifying the relationship between changes in these biomarkers and head impacts experienced by female soccer athletes may prove valuable to developing preventative measures for mTBI. This study paired functional magnetic resonance imaging with head impact monitoring to track cerebrovascular reactivity changes throughout a season and to test whether the observed changes could be attributed to mechanical loading experienced by female athletes participating in high school soccer. Marked cerebrovascular reactivity changes were observed in female soccer athletes, relative both to non-collision sport control measures and pre-season measures and were localized to fronto-temporal aspects of the brain. These changes persisted 4\textendash5 months after the season ended and recovered by 8 months after the season. Segregation of the total soccer cohort into cumulative loading groups revealed that population-level changes were driven by athletes experiencing high cumulative loads, although athletes experiencing lower cumulative loads still contributed to group changes. The results of this study imply a non-linear relationship between cumulative loading and cerebrovascular changes with a threshold, above which the risk, of injury likely increases significantly.

Material and methods Our evaluation was based on questionnaire about diagnosis and management of concussion. For each club, we included at least one player and one staff member (manager, medical team member or coach). Results One hundred and sixty-three subjects (37 players and 126 staff members) of 47 clubs were included. For all subjects, the loss of conscious was a symptom of concussion but only 61% could give 3 others symptoms. The risk of a second accident during days after concussion was known by 95%. About primary care, 50% did not look for cervical spine accident just after brain concussion and 22% thought that concussed athletes could finish the game. A majority of our study population (89%) would not leave alone an injured player after the trauma. This study shows some deficiencies in identification of concussion. The questions about primary care indicate some problems that can cause additional accident. © 2016},

Treatment for concussion is an emerging area of focus with investigators seeking to improve outcomes and protect patients from the deleterious short-term and long-term consequences which have been extensively studied and identified. Broadly, current treatment strategies for athletes recovering from concussion have remained largely unchanged since early 2000s. Knowledge of the complex pathophysiology surrounding injury should improve or advance our ability to identify processes which may serve as targets for therapeutic intervention. Clinicians working with athletes recovering from sports-related concussion should have an advanced understanding of the injury cascade and also be aware of the current efforts within the research to treat concussion. In addition, how clinicians use the word "treatment" should be carefully defined and promoted so the patient is aware of the level of intervention and what stage of recovery or healing is being affected by a specific intervention. The purpose of this review is to bring together efforts across disciplines of brain science into 1 platform where clinicians can assimilate this information before making best practices decisions regarding the treatment of patients and athletes under their care. © 2016 Wolters Kluwer Health, Inc.

Limited data exist, however, examining dual-task gait data consistency collected over time in healthy individuals. The study purposes were to: 1) assess the consistency of single-task and dual-task gait balance control measures, 2) determine the minimal detectable change (MDC) of gait balance control measures, and 3) examine the extent to which age and task complexity affect dual-task walking costs in healthy adolescents and young adults. Twenty-four adolescent (mean age=15.5±1.1years) and 21 young adult (mean age=21.2±4.5years) healthy participants completed 5 testing sessions across a two-month period, which involved analyses of gait balance control and temporal-distance variables during single-task and dual-task walking conditions in a motion analysis laboratory. Cronbach's $alpha$ and MDCs were used to determine the consistency of the gait balance control variables and the smallest amount of change required to distinguish true performance from change due to the performance/measurement variability, respectively. Dual-task costs were evaluated to determine the effect of task complexity and age across time using 3-way ANOVAs. Good to excellent test-retest consistency was found for all single-task and dual-task walking (Cronbach's $alpha$ range: 0.764-0.970), with a center-of-mass medial-lateral displacement MDC range of 0.835-0.948cm. Greater frontal plane dual-task costs were observed during more complex secondary tasks (p\<0.001). The results revealed good-excellent consistency across testing sessions for all variables and indicated dual-task costs are affected by task complexity. Thus, healthy controls can be effective comparators when assessing injured subjects. [ABSTRACT FROM AUTHOR]},

abstract = {The relation between resilience and mild traumatic brain injury (TBI) outcome has been theorized but empirical studies have been scarce. This systematic review aimed to describe the research in this area. Electronic databases (Medline, CINAHL, PsychINFO, SPORTdiscus, and PILOTS) were searched from inception to August 2015 for studies in which resilience was measured following TBI. The search terms included ‘TBI’ ‘concussion’ ‘postconcussion’ ‘resilience’ and ‘hardiness’. Inclusion criteria were peer reviewed original research reports published in English, human participants aged 18 years and over with brain injury, and an accepted definition of mild TBI. Hand searching of identified articles was also undertaken. Of the 71 studies identified, five studies were accepted for review. These studies were formally assessed for risk of bias by two independent reviewers. Each study carried a risk of bias, most commonly a detection bias, but none were excluded on this basis. A narrative interpretation of the findings was used because the studies reflected fundamental differences in the conceptualization of resilience. No studies employed a trajectory based approach to measure a resilient outcome. In most cases, the eligible studies assessed trait resilience with a scale and used it as a predictor of outcome (postconcussion symptoms). Three of these studies showed that greater trait resilience was associated with better mild TBI outcomes (fewer symptoms). Future research of the adult mild TBI response that predicts a resilient outcome is encouraged. These studies could yield empirical evidence for a resilient, and other possible mild TBI outcomes. © 2016, Springer Science+Business Media New York.},

abstract = {Emerging research on the long-term impact of concussions on athletes has allowed public recognition of the potentially devastating effects of these and other mild head injuries. Mild traumatic brain injury (mTBI) is a multifaceted disease for which management remains a clinical challenge. Recent pre-clinical and clinical data strongly suggest a destructive synergism between brain temperature elevation and mTBI; conversely, brain hypothermia, with its broader, pleiotropic effects, represents the most potent neuro-protectant in laboratory studies to date. Although well-established in selected clinical conditions, a systemic approach to accomplish regional hypothermia has failed to yield an effective treatment strategy in traumatic brain injury (TBI). Furthermore, although systemic hypothermia remains a potentially valid treatment strategy for moderate to severe TBIs, it is neither practical nor safe for mTBIs. Therefore, selective head-neck cooling may represent an ideal strategy to provide therapeutic benefits to the brain. Optimizing brain temperature management using a National Aeronautics and Space Administration (NASA) spacesuit spinoff head-neck cooling technology before and/or after mTBI in contact sports may represent a sensible, practical, and effective method to potentially enhance recover and minimize post-injury deficits. In this paper, we discuss and summarize the anatomical, physiological, preclinical, and clinical data concerning NASA spinoff head-neck cooling technology as a potential treatment for mTBIs, particularly in the context of contact sports. © 2015 Huan Wang et al., licensee De Gruyter Open.},

abstract = {Using metrics that permit detailed analysis of sway variability, the authors demonstrate the capacity to detect alterations in postural control among youth who sustained concussion. Purpose: The purpose of this study was to evaluate the utility of postural sway variability as a potential assessment to detect altered postural sway in youth with symptoms related to a concussion. Methods: Forty participants (20 who were healthy and 20 who were injured) aged 10 to 16 years were assessed using the Balance Error Scoring System (BESS) and postural sway variability analyses applied to center-of-pressure data captured using a force plate. Results: Significant differences were observed between the 2 groups for postural sway variability metrics but not for the BESS. Specifically, path length was shorter and Sample and Renyi Entropies were more regular for the participants who were injured compared with the participants who were healthy (P \<.05). Conclusion: The results of this study indicate that postural sway variability may be a more valid measure than the BESS to detect postconcussion alterations in postural control in young athletes. © 2015 Wolters Kluwer Health, Inc.},

abstract = {BACKGROUND: Mild traumatic brain injury (mTBI) constitutes 75% of more than 1.5 million traumatic brain injuries annually. There exists no consensus on point-of-care screening for mTBI. The Military Acute Concussion Evaluation (MACE) is a quick and easy test used by the US Army to screen for mTBI; however, its utility in civilian trauma is unclear. It has two parts: a history section and the Standardized Assessment of Concussion (SAC) score (0-30) previously validated in sports injury. As a performance improvement project, our institution sought to evaluate the MACE as a concussion screening tool that could be used by housestaff in a general civilian trauma population. METHODS: From June 2013 to May 2014, patients 18 years to 65 years old with suspected concussion were given the MACE within 72 hours of admission to our urban Level I trauma center. Patients with a positive head computed tomography were excluded. Demographic data and MACE scores were recorded in prospect. Concussion was defined as loss of consciousness and/or posttraumatic amnesia; concussed patients were compared with those nonconcussed. Sensitivity and specificity for each respective MACE score were used to plot a receiver operating characteristic (ROC) curve. An ROC curve area of 0.8 was set as the benchmark for a good screening test to distinguish concussion from nonconcussion. RESULTS: There were 84 concussions and 30 nonconcussed patients. Both groups were similar; however, the concussion group had a lower mean MACE score than the nonconcussed patients. Data analysis demonstrated the sensitivity and specificity of a range of MACE scores used to generate an ROC curve area of only 0.65. CONCLUSION: The MACE showed a lower mean score for individuals with concussion, defined by loss of consciousness and/or posttraumatic amnesia. However, the ROC curve area of 0.65 highly suggests that MACE alone would be a poor screening test for mTBI in a general civilian trauma population. LEVEL OF EVIDENCE: Diagnostic study, level II.

abstract = {Traumatic brain injury (TBI), including concussion, is a public health concern, as it affects over 1.7 million persons in the United States per year. Yet, the diagnosis of TBI, particularly mild TBI (mTBI), can be controversial, as neuroimaging findings can be sparse on conventional magnetic resonance and computed tomography examinations, and when present, often poorly correlate with clinical signs and symptoms. Furthermore, the discussion of TBI, concussion, and head impact exposure is immediately complicated by the many differing opinions of what constitutes each, their respective severities, and how the underlying biomechanics of the inciting head impact might alter the distribution, severity, and prognosis of the underlying brain injury. Advanced imaging methodologies hold promise in improving the sensitivity and detectability of associated imaging biomarkers that might better correlate with patient outcome and prognostication, allowing for improved triage and therapeutic guidance in the setting of TBI, particularly in mTBI. This work will examine the defining symptom complex associated with mTBI and explore changes in cerebral blood flow measured by arterial spin labeling, as a potential imaging biomarker for TBI, and briefly correlate these observations with findings identified by single photon emission computed tomography and positron emission tomography imaging..

abstract = {Objective: Obtaining baseline neuropsychological (NP) data to assist management of sports-related concussion has been considered the standard of care. The validity of this approach has been questioned, with suggestions that post-concussion testing alone will suffice. The present study compared the sensitivity of baseline and normative paradigms in the setting of sports-related concussion. Method: Baseline NP data were collected for 194 Australian rugby league athletes on a brief battery of paper-and-pencil NP tests. During competition, 27 athletes sustaining concussion referred from a sports physician were retested within two days of injury. Twenty-six uninjured controls were assessed at similar intervals. The baseline paradigm was assessed using a reliable change index for pre- and post-concussion scores. The normative paradigm was assessed comparing the post-concussion score to a normative mean. Results: The baseline paradigm was consistently more sensitive to negative change following concussion than the normative paradigm when using continuous data, despite reasonable agreement. However, when data were categorised as 'impaired' or 'not-impaired', using either 68% or 90% confidence intervals, the difference between paradigms failed to reach significance. Comparison of ROC curves for both paradigms found superior overall classification for one test and the composite score using baseline comparison data. Conclusions: Despite being a time and resource intensive process, the baseline paradigm as a repeated-measures design may be more sensitive than the between-subjects design of the normative paradigm for detecting changes following concussion. Further work is required to determine the validity of normative assessment in sports-related concussion. Copyright © Australasian Society for the Study of Brain Impairment 2015.},

Baseline neurocognitive testing was conducted pre-season in Grade 7 and post-season in Grades 8 and 9. Year-end academic grades were documented for Grades 6-9 and 12 (pre-high school to year of school leaving). A mixed model repeated measures ANOVA was conducted to investigate comparative neurocognitive and academic outcomes between the three sub-groups.Results: Compared with controls, both rugby groups were significantly lower on the WISC-III Coding Immediate Recall sub-test. There was a significant interaction effect on the academic measure, with improved scores over time for controls, that was not in evidence for either rugby group.Conclusions: Tentatively, the outcome suggests cognitive vulnerability in association with school level participation in rugby. © 2015 Taylor \& Francis Group, LLC.},

abstract = {Purpose: Approximately 90% of concussions are transient, with symptoms resolving within 10\textendash14 days. However, a minority of patients remain symptomatic several months post-injury, a condition known as post-concussion syndrome (PCS). The treatment of these patients can be challenging. The goal of our study was to assess the utility and cost-effectiveness of neurologic imaging two or more weeks post-injury in a cohort of youth with PCS. Methods: We conducted a retrospective study of 52 pediatric patients with persistent post-concussion symptoms after 3 months. We collected demographics and neuroimaging results obtained greater than 2 weeks post-concussion. Neuroimaging ordered in the first 2 weeks post-concussion was excluded, except to determine the rate of re-imaging. Descriptive statistics and corresponding cost data were collected. Results: Of 52 patients with PCS, 23/52 (44 %) had neuroimaging at least 2 weeks after the initial injury, for a total of 32 diagnostic studies. In summary, 1/19 MRIs (5.3 %), 1/8 CTs (13 %), and 0/5 x-rays (0 %) yielded significant positive findings, none of which altered clinical management. Chronic phase neuroimaging estimated costs from these 52 pediatric patients totaled $129,025. We estimate the cost to identify a single positive finding was $21,000 for head CT and $104,500 for brain MRI. Conclusions: In this cohort of pediatric PCS patients, brain imaging in the chronic phase (defined as more than 2 weeks after concussion) was pursued in almost half the study sample, had low diagnostic yield, and had poor cost-effectiveness. Based on these results, outpatient management of pediatric patients with long-term post-concussive symptoms should rarely include repeat neuroimaging beyond the acute phase. © 2015, Springer-Verlag Berlin Heidelberg.},

abstract = {Background: Sports are a major cause of concussions, and little is known about the symptom experience and health-related quality of life (HRQL) in children who remain symptomatic for over 3 months following such head injuries. Methods: A cross-sectional study of children aged 10-18 years was performed who were referred to the Neurosurgery Clinic at our centre following a head injury. Symptom experience was measured using the modified Concussion Symptom Scale, and HRQL was measured using the Pediatric Quality of Life Inventory (PedsQL). The Immediate Postconcussion Assessment and Cognitive Test (ImPACT) was administered to assess neurocognitive and neurobehavioural sequelae. Results: Symptoms with the highest mean symptom scores on a Likert scale of 0-6 in 35 children at the time of assessment included headaches (3.1), poor concentration (2.7), memory problems (2.1), fatigue (2.1) and sensitivity to noise (2.0). Compared with normative data, children in this study had ImPACT summary scores between the 28th and 38th percentiles and a comparably low Cognitive Efficiency Index score. Mean scores for females were consistently statistically significantly lower (p \< 0.05) than for males across all of the HRQL domains. Trouble falling asleep and memory problems explained 62% of the variance in the PedsQL total scores. Conclusions: Children continue to experience many symptoms at least 3 months following sport-related head injuries that significantly impact their HRQL and neurocognitive abilities. © 2015 S.

abstract = {Context: Chronic traumatic encephalopathy (CTE) is a rare progressive neurologic disorder that can manifest as a combination of cognitive, mood and behavioral, and neurologic symptoms. Despite clinically apparent symptoms, there is no imaging or other diagnostic test that can confirm diagnosis in living subjects. Diagnosis can only be confirmed postmortem by specific histopathologic features within the brain tissue identified on autopsy. CTE represents a unique tauopathy that is distinct from other neurodegenerative diseases. Evidence Acquisition: PubMed was searched from 1990 to 2013 for sport concussion and chronic traumatic encephalopathy. Articles were also identified from bibliographies of recent reviews and consensus statements. Study Design: Clinical review. Level of Evidence: Level 5. Results: Although CTE is postulated to occur as a result of repetitive mild traumatic brain injury, the specific etiology and risk factors have not yet been elucidated, and postmortem diagnosis makes causality difficult to determine. Conclusion: When counseling athletes and families about the potential association of recurrent concussions and the development of CTE, discussion of proper management of concussion is cornerstone. Unfortunately, to date, there is no equipment that can prevent concussions; however, rule changes and legislation may decrease the risk. It is imperative that return to play is medically supervised by a provider trained in the management of concussion and begins only once symptoms have resolved. In addition, athletes with permanent symptoms should be retired from contact sport. © 2014 The Author(s).},

Evidence based diagnostic guidelines have been established,1 but the diagnosis and treatment are largely grounded in clinical decision-making. Clinical and research issues around sports concussion have even reached the levels of government policy with the White House. At the moderate to severe range of traumatic brain injury, neuroimaging provides well-established, objective pathoanatomical biomarkers of the injury. In contrast, conventional neuroimaging findings in mTBI are typically absent. The cognitive and neurobehavioral symptoms of mTBI overlap with any number of neurologic or psychiatric disorders, providing no definitive marker of injury or for tracking injury effects. Reliable biomarkers of mTBI could lead to better clinical decision-making and potential treatments. Deformation-based biomechanical studies of mTBI have shown the thalamus is situated in a particularly vulnerable zone. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

(The following abstract of the original article appeared in record [rid]2010-23062-009[/rid]). Concussive head injury opens a temporary window of brain vulnerability due to the impairment of cellular energetic metabolism. As experimentally demonstrated, a second mild injury occurring during this period can lead to severe brain damage, a condition clinically described as the second impact syndrome. To corroborate the validity of proton magnetic resonance spectroscopy in monitoring cerebral metabolic changes following mild traumatic brain injury, apart from the magnetic field strength (1.5 or 3.0 T) and mode of acquisition, we undertook a multicentre prospective study in which a cohort of 40 athletes suffering from concussion and a group of 30 control healthy subjects were admitted. Athletes (aged 16\textendash35 years) were recruited and examined at three different institutions between September 2007 and June 2009. They underwent assessment of brain metabolism at 3, 15, 22 and 30 days post-injury through proton magnetic resonance spectroscopy for the determination of N-acetylaspartate, creatine and choline-containing compounds. Values of these representative brain metabolites were compared with those observed in the group of non-injured controls. Comparison of spectroscopic data, obtained in controls using different field strength and/or mode of acquisition, did not show any difference in the brain metabolite ratios. Athletes with concussion exhibited the most significant alteration of metabolite ratios at Day 3 post-injury (N-acetylaspartate/creatine: −17.6%, N-acetylaspartate/choline: −21.4%; P \< 0.001 with respect to controls). On average, metabolic disturbance gradually recovered, initially in a slow fashion and, following Day 15, more rapidly. At 30 days post-injury, all athletes showed complete recovery, having metabolite ratios returned to values detected in controls. Athletes self-declared symptom clearance between 3 and 15 days after concussion. Results indicate that N-acetylaspartate determination by proton magnetic resonance spectroscopy represents a non-invasive tool to accurately measure changes in cerebral energy metabolism occurring in mild traumatic brain injury. In particular, this metabolic evaluation may significantly improve, along with other clinical assessments, the management of athletes suffering from concussion. Further studies to verify the effects of a second concussive event occurring at different time points of the recovery curve of brain metabolism are needed.

Despite the ubiquity of vestibular disturbance in this population, there remains a dearth of research on the interaction between physiological and cognitive systems responsible for maintaining balance. PURPOSE: The purpose of this article is to review studies on the interaction of physiological and cognitive processes required to maintain balance that may aide assessment and recovery of balance disturbance in patients with brain injury. SUMMARY: This article provides a review of research on the role of higher order cognitive processes in maintaining balance and rational for further inclusion of neurocognitive measures in the assessment of vestibular disturbance. CONCLUSION: Greater inclusion of neurocognitive measures in assessment of vestibular disturbance provides a method of assessment containing increased ecological validity compared to traditional assessments, better prepares patients for discharge, and may reduce the incidence of future injury.},

Two different approaches to intervention and treatment for those with a suspected concussion from a work-related injury were utilised by an urban, interdisciplinary, outpatient rehabilitation facility. The first approach, Group Treatment (GT), provided minimal early education at time of initial intake, emphasising an extensive group-focused interdisciplinary assessment and treatment. The second approach, Individualized Education and Treatment, (IET) emphasised early education, instead coupled with specific individualised services. Both groups received employment services. Post-discharge, GT ( N = 26) resulted in 46% ( n = 12) of individuals returning to competitive employment, while IET ( N = 23) resulted in 78% ( n = 18) of individuals returning to competitive employment. An asset-oriented early individualised educational approach appears to be a more effective for employment re-engagement. ABSTRACT FROM AUTHOR},

abstract = {Primary objective: To evaluate low-level to complex information processing using visual electrophysiology and to examine the latter's prognostic value in regards to vocational outcome in persons having sustained a mild traumatic brain injury (mTBI). Research design/methods: Event-related potentials (ERPs) were recorded to pattern-reversal, simple motion, texture segregation and cognitive oddball paradigms from 17 participants with symptomatic mTBI at onset of specialized clinical intervention and from 15 normal controls. The relationship between abnormal electrophysiology and post-intervention return to work status was also examined. Main outcomes and results: Participants with mTBI showed a statistically significant (p \< .05) amplitude reduction for cognitive ERPs and delayed latencies for texture (p \< .05) and cognitive paradigms (p \< .005) compared to controls. Furthermore, participants with mTBI presenting texture or cognitive ERP latency delays upon admission were at significantly (p \< .01) greater risk of negative vocational outcome than mTBI participants with normal electrophysiology. Conclusions: The findings suggest that individuals with symptomatic mTBI can present selective deficits in complex visual information processing that could interfere with vocational outcome. ERP paradigms such as those employed in this study thus show potential for evaluating outcome prognosis and merit further study. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

Design Retrospective cohort. Main measures Post-Concussion Symptom Scale (PCSS) total score, maximum symptom-free heart rate (SFHR) during graded exercise testing (GXT), GXT duration, balance error scoring system (BESS) score, and number of adverse events. Results Patients demonstrated a statistically significant decreasing trend (p \< 0.01) for total PCSS scores (pre-PT M = 18.2 (SD = 14.2), post-PT M = 9.1 (SD = 10.8), n = 25). Maximum SFHR achieved on GXT increased 23% (p \< 0.01, n = 14), and BESS errors decreased 52% (p \< 0.01, n = 13). Two patients reported mild symptom exacerbation with aerobic exercise at home, attenuated by adjustment of the home exercise program. Conclusions Multimodal, impairment-based PT is safe and associated with diminishing PCS symptoms. This establishes feasibility for future clinical trials to determine viable treatment approaches to reduce symptoms and improve function while avoiding negative repercussions of physical inactivity and premature return to full activity. © 2016 Elsevier Ltd},

abstract = {Background: Concussions are a common pathology in football and multiple misconceptions exist amongst the players and managers. To address these misconceptions, and potentially reduce concussion associated sequela, effective educational interventions need to be developed. However, the current knowledge and attitude status must be ascertained to appropriately develop these interventions. The purpose of this study was to assess the concussion knowledge and attitude of English professional footballers. Methods: Twenty-six participants from one English Football League Championship club completed the study. A mixed methods approach included the Rosenbaum Concussion Knowledge and Attitudes Survey (RoCKAS) and a semi-structured interview. The RoCKAS contains separate knowledge (0-25) and attitude (15-75) scores and was followed by a semi-structured interview consisting of concussion knowledge, attitude, and behavior related questions. Results: The mean score on the RoCKAS knowledge was 16.4 ± 2.9 (range 11-22) and the attitude score was 59.6 ± 8.5 (range 41-71). The interview responses identified inconsistencies between the RoCKAS and the intended behaviors, endorsing multiple concussion misconceptions, and revealed barriers to concussion reporting. Conclusion: The results of this study suggest that Championship Level English footballers have moderate concussion knowledge, safe attitudes, and good concussion symptom recognition when assessed with pen and paper questionnaires. However, within the semi-structured interview many respondents reported unsafe concussion behaviors despite accurately identifying the potential risks. Further, multiple barriers to concussion reporting were identified which included perceived severity of the injury, game situations, and the substitution rule. These findings can help form the foundation of educational interventions to potentially improve concussion reporting behaviors amongst professional footballers. © 2016.},

Sport psychiatrists are increasingly called to be part of the concussion team and need to be prepared to manage issues related to concussion and its behavioural sequelae. Objectively, the best evidence available suggests that deficits in attention and/or in balance are the most reliable objective findings that a concussion has occurred. Prognosis after a concussion is generally very good, although a sub-set of patients that are yet well defined seem pre-disposed to delayed recovery. Neither head CT nor MRI are sufficiently sensitive to diagnose the type of injuries that pre-dispose patients to the neurobehavioural sequelae that have been associated with a concussion; confounding this is the finding that many of these signs and symptoms associated with concussion occur in other types of non-head injuries. Brain biomarkers and functional MRI (fMRI) hold promise in both diagnosis and prognosis of concussion, but are still research tools without validated clinical utility at this time. Finally, neurocognitive testing holds promise as a diagnostic criterion to demonstrate injury but, unfortunately, these tests are also limited in their prognostic utility and are of limited value. © 2016 Institute of Psychiatry and John Hopkins University.},

abstract = {Background: Concussions have been associated with elevated musculoskeletal injury risk; however, the influence of unreported and unrecognized concussions has not been investigated. Hypothesis: The purpose of this study was to examine the association between concussion and lower extremity musculoskeletal injury rates across a diverse array of sports among collegiate student-athletes at the conclusion of their athletic career. The hypothesis was that there will be a positive association between athletes who reported a history of concussions and higher rates of lower extremity injuries. Study Design: Cross-sectional study. Level of Evidence: Level 3. Methods: Student-athletes (N = 335; 62.1% women; mean age, 21.2 ± 1.4 years) from 13 sports completed a reliable injury history questionnaire. Respondents indicated the total number of reported, unreported, and potentially unrecognized concussions as well as lower extremity injuries including ankle sprains, knee injuries, and muscle strains. Chi-square analyses were performed to identify the association between concussion and lower extremity injuries. Results: There were significant associations between concussion and lateral ankle sprain (P = 0.012), knee injury (P = 0.002), and lower extremity muscle strain (P = 0.031). There were also significant associations between reported concussions and knee injury (P = 0.003), unreported concussions and knee injury (P = 0.002), and unrecognized concussions and lateral ankle sprain (P = 0.001) and lower extremity muscle strains (P = 0.006), with odds ratios ranging from 1.6 to 2.9. Conclusion: There was a positive association between concussion history and lower extremity injuries (odds ratios, 1.6-2.9 elevated risk) among student-athletes at the conclusion of their intercollegiate athletic careers. Clinical Relevance: Clinicians should be aware of these elevated risks when making return-to-participation decisions and should incorporate injury prevention protocols. © 2016, © 2016 The Author(s).},

abstract = {As participation in women’s soccer continues to grow and the longevity of female athletes’ careers continues to increase, prevention and care for mTBI in women’s soccer has become a major concern for female athletes since the long-term risks associated with a history of mTBI are well documented. Among women’s sports, soccer exhibits among the highest concussion rates, on par with those of men’s football at the collegiate level. Head impact monitoring technology has revealed that 'concussive hits' occurring directly before symptomatic injury are not predictive of mTBI, suggesting that the cumulative effect of repetitive head impacts experienced by collision sport athletes should be assessed. Neuroimaging biomarkers have proven to be valuable in detecting brain changes that occur before neurocognitive symptoms in collision sport athletes. Quantifying the relationship between changes in these biomarkers and head impacts experienced by female soccer athletes may prove valuable to developing preventative measures for mTBI. This study paired functional magnetic resonance imaging with head impact monitoring to track cerebrovascular reactivity changes throughout a season and to test whether the observed changes could be attributed to mechanical loading experienced by female athletes participating in high school soccer. Marked cerebrovascular reactivity changes were observed in female soccer athletes, relative both to non-collision sport control measures and pre-season measures and were localized to fronto-temporal aspects of the brain. These changes persisted 4\textendash5 months after the season ended and recovered by 8 months after the season. Segregation of the total soccer cohort into cumulative loading groups revealed that population-level changes were driven by athletes experiencing high cumulative loads, although athletes experiencing lower cumulative loads still contributed to group changes. The results of this study imply a non-linear relationship between cumulative loading and cerebrovascular changes with a threshold, above which the risk, of injury likely increases significantly.

Results One hundred and sixty-three subjects (37 players and 126 staff members) of 47 clubs were included. For all subjects, the loss of conscious was a symptom of concussion but only 61% could give 3 others symptoms. The risk of a second accident during days after concussion was known by 95%. About primary care, 50% did not look for cervical spine accident just after brain concussion and 22% thought that concussed athletes could finish the game. A majority of our study population (89%) would not leave alone an injured player after the trauma. This study shows some deficiencies in identification of concussion. The questions about primary care indicate some problems that can cause additional accident. © 2016},

Treatment for concussion is an emerging area of focus with investigators seeking to improve outcomes and protect patients from the deleterious short-term and long-term consequences which have been extensively studied and identified. Broadly, current treatment strategies for athletes recovering from concussion have remained largely unchanged since early 2000s. Knowledge of the complex pathophysiology surrounding injury should improve or advance our ability to identify processes which may serve as targets for therapeutic intervention. Clinicians working with athletes recovering from sports-related concussion should have an advanced understanding of the injury cascade and also be aware of the current efforts within the research to treat concussion. In addition, how clinicians use the word "treatment" should be carefully defined and promoted so the patient is aware of the level of intervention and what stage of recovery or healing is being affected by a specific intervention. The purpose of this review is to bring together efforts across disciplines of brain science into 1 platform where clinicians can assimilate this information before making best practices decisions regarding the treatment of patients and athletes under their care. © 2016 Wolters Kluwer Health, Inc.

Limited data exist, however, examining dual-task gait data consistency collected over time in healthy individuals. The study purposes were to: 1) assess the consistency of single-task and dual-task gait balance control measures, 2) determine the minimal detectable change (MDC) of gait balance control measures, and 3) examine the extent to which age and task complexity affect dual-task walking costs in healthy adolescents and young adults. Twenty-four adolescent (mean age=15.5±1.1years) and 21 young adult (mean age=21.2±4.5years) healthy participants completed 5 testing sessions across a two-month period, which involved analyses of gait balance control and temporal-distance variables during single-task and dual-task walking conditions in a motion analysis laboratory. Cronbach's $alpha$ and MDCs were used to determine the consistency of the gait balance control variables and the smallest amount of change required to distinguish true performance from change due to the performance/measurement variability, respectively. Dual-task costs were evaluated to determine the effect of task complexity and age across time using 3-way ANOVAs. Good to excellent test-retest consistency was found for all single-task and dual-task walking (Cronbach's $alpha$ range: 0.764-0.970), with a center-of-mass medial-lateral displacement MDC range of 0.835-0.948cm. Greater frontal plane dual-task costs were observed during more complex secondary tasks (p\<0.001). The results revealed good-excellent consistency across testing sessions for all variables and indicated dual-task costs are affected by task complexity. Thus, healthy controls can be effective comparators when assessing injured subjects. [ABSTRACT FROM AUTHOR]},

abstract = {The relation between resilience and mild traumatic brain injury (TBI) outcome has been theorized but empirical studies have been scarce. This systematic review aimed to describe the research in this area. Electronic databases (Medline, CINAHL, PsychINFO, SPORTdiscus, and PILOTS) were searched from inception to August 2015 for studies in which resilience was measured following TBI. The search terms included ‘TBI’ ‘concussion’ ‘postconcussion’ ‘resilience’ and ‘hardiness’. Inclusion criteria were peer reviewed original research reports published in English, human participants aged 18 years and over with brain injury, and an accepted definition of mild TBI. Hand searching of identified articles was also undertaken. Of the 71 studies identified, five studies were accepted for review. These studies were formally assessed for risk of bias by two independent reviewers. Each study carried a risk of bias, most commonly a detection bias, but none were excluded on this basis. A narrative interpretation of the findings was used because the studies reflected fundamental differences in the conceptualization of resilience. No studies employed a trajectory based approach to measure a resilient outcome. In most cases, the eligible studies assessed trait resilience with a scale and used it as a predictor of outcome (postconcussion symptoms). Three of these studies showed that greater trait resilience was associated with better mild TBI outcomes (fewer symptoms). Future research of the adult mild TBI response that predicts a resilient outcome is encouraged. These studies could yield empirical evidence for a resilient, and other possible mild TBI outcomes. © 2016, Springer Science+Business Media New York.},

abstract = {Emerging research on the long-term impact of concussions on athletes has allowed public recognition of the potentially devastating effects of these and other mild head injuries. Mild traumatic brain injury (mTBI) is a multifaceted disease for which management remains a clinical challenge. Recent pre-clinical and clinical data strongly suggest a destructive synergism between brain temperature elevation and mTBI; conversely, brain hypothermia, with its broader, pleiotropic effects, represents the most potent neuro-protectant in laboratory studies to date. Although well-established in selected clinical conditions, a systemic approach to accomplish regional hypothermia has failed to yield an effective treatment strategy in traumatic brain injury (TBI). Furthermore, although systemic hypothermia remains a potentially valid treatment strategy for moderate to severe TBIs, it is neither practical nor safe for mTBIs. Therefore, selective head-neck cooling may represent an ideal strategy to provide therapeutic benefits to the brain. Optimizing brain temperature management using a National Aeronautics and Space Administration (NASA) spacesuit spinoff head-neck cooling technology before and/or after mTBI in contact sports may represent a sensible, practical, and effective method to potentially enhance recover and minimize post-injury deficits. In this paper, we discuss and summarize the anatomical, physiological, preclinical, and clinical data concerning NASA spinoff head-neck cooling technology as a potential treatment for mTBIs, particularly in the context of contact sports. © 2015 Huan Wang et al., licensee De Gruyter Open.},

Methods: Forty participants (20 who were healthy and 20 who were injured) aged 10 to 16 years were assessed using the Balance Error Scoring System (BESS) and postural sway variability analyses applied to center-of-pressure data captured using a force plate. Results: Significant differences were observed between the 2 groups for postural sway variability metrics but not for the BESS. Specifically, path length was shorter and Sample and Renyi Entropies were more regular for the participants who were injured compared with the participants who were healthy (P \<.05).

abstract = {BACKGROUND: Mild traumatic brain injury (mTBI) constitutes 75% of more than 1.5 million traumatic brain injuries annually. There exists no consensus on point-of-care screening for mTBI. The Military Acute Concussion Evaluation (MACE) is a quick and easy test used by the US Army to screen for mTBI; however, its utility in civilian trauma is unclear. It has two parts: a history section and the Standardized Assessment of Concussion (SAC) score (0-30) previously validated in sports injury. As a performance improvement project, our institution sought to evaluate the MACE as a concussion screening tool that could be used by housestaff in a general civilian trauma population. METHODS: From June 2013 to May 2014, patients 18 years to 65 years old with suspected concussion were given the MACE within 72 hours of admission to our urban Level I trauma center. Patients with a positive head computed tomography were excluded. Demographic data and MACE scores were recorded in prospect. Concussion was defined as loss of consciousness and/or posttraumatic amnesia; concussed patients were compared with those nonconcussed. Sensitivity and specificity for each respective MACE score were used to plot a receiver operating characteristic (ROC) curve. An ROC curve area of 0.8 was set as the benchmark for a good screening test to distinguish concussion from nonconcussion. RESULTS: There were 84 concussions and 30 nonconcussed patients. Both groups were similar; however, the concussion group had a lower mean MACE score than the nonconcussed patients. Data analysis demonstrated the sensitivity and specificity of a range of MACE scores used to generate an ROC curve area of only 0.65. CONCLUSION: The MACE showed a lower mean score for individuals with concussion, defined by loss of consciousness and/or posttraumatic amnesia. However, the ROC curve area of 0.65 highly suggests that MACE alone would be a poor screening test for mTBI in a general civilian trauma population. LEVEL OF EVIDENCE: Diagnostic study, level II.

abstract = {Traumatic brain injury (TBI), including concussion, is a public health concern, as it affects over 1.7 million persons in the United States per year. Yet, the diagnosis of TBI, particularly mild TBI (mTBI), can be controversial, as neuroimaging findings can be sparse on conventional magnetic resonance and computed tomography examinations, and when present, often poorly correlate with clinical signs and symptoms. Furthermore, the discussion of TBI, concussion, and head impact exposure is immediately complicated by the many differing opinions of what constitutes each, their respective severities, and how the underlying biomechanics of the inciting head impact might alter the distribution, severity, and prognosis of the underlying brain injury. Advanced imaging methodologies hold promise in improving the sensitivity and detectability of associated imaging biomarkers that might better correlate with patient outcome and prognostication, allowing for improved triage and therapeutic guidance in the setting of TBI, particularly in mTBI. This work will examine the defining symptom complex associated with mTBI and explore changes in cerebral blood flow measured by arterial spin labeling, as a potential imaging biomarker for TBI, and briefly correlate these observations with findings identified by single photon emission computed tomography and positron emission tomography imaging..

The validity of this approach has been questioned, with suggestions that post-concussion testing alone will suffice. The present study compared the sensitivity of baseline and normative paradigms in the setting of sports-related concussion. Method: Baseline NP data were collected for 194 Australian rugby league athletes on a brief battery of paper-and-pencil NP tests. During competition, 27 athletes sustaining concussion referred from a sports physician were retested within two days of injury. Twenty-six uninjured controls were assessed at similar intervals. The baseline paradigm was assessed using a reliable change index for pre- and post-concussion scores. The normative paradigm was assessed comparing the post-concussion score to a normative mean. Results: The baseline paradigm was consistently more sensitive to negative change following concussion than the normative paradigm when using continuous data, despite reasonable agreement. However, when data were categorised as 'impaired' or 'not-impaired', using either 68% or 90% confidence intervals, the difference between paradigms failed to reach significance. Comparison of ROC curves for both paradigms found superior overall classification for one test and the composite score using baseline comparison data. Conclusions: Despite being a time and resource intensive process, the baseline paradigm as a repeated-measures design may be more sensitive than the between-subjects design of the normative paradigm for detecting changes following concussion. Further work is required to determine the validity of normative assessment in sports-related concussion. Copyright © Australasian Society for the Study of Brain Impairment 2015.},

Baseline neurocognitive testing was conducted pre-season in Grade 7 and post-season in Grades 8 and 9. Year-end academic grades were documented for Grades 6-9 and 12 (pre-high school to year of school leaving). A mixed model repeated measures ANOVA was conducted to investigate comparative neurocognitive and academic outcomes between the three sub-groups.Results: Compared with controls, both rugby groups were significantly lower on the WISC-III Coding Immediate Recall sub-test. There was a significant interaction effect on the academic measure, with improved scores over time for controls, that was not in evidence for either rugby group.Conclusions: Tentatively, the outcome suggests cognitive vulnerability in association with school level participation in rugby. © 2015 Taylor \& Francis Group, LLC.},

Setting University hospital outpatient sports medicine facility. Participants Twenty-five patients (12\textendash20 years old) meeting World Health Organization criteria for PCS following sport-related concussion referred for supervised PT consisting of sub-symptom cardiovascular exercise, vestibular/oculomotor and cervical spine rehabilitation. Design Retrospective cohort. Main measures Post-Concussion Symptom Scale (PCSS) total score, maximum symptom-free heart rate (SFHR) during graded exercise testing (GXT), GXT duration, balance error scoring system (BESS) score, and number of adverse events. Results Patients demonstrated a statistically significant decreasing trend (p \< 0.01) for total PCSS scores (pre-PT M = 18.2 (SD = 14.2), post-PT M = 9.1 (SD = 10.8), n = 25). Maximum SFHR achieved on GXT increased 23% (p \< 0.01, n = 14), and BESS errors decreased 52% (p \< 0.01, n = 13). Two patients reported mild symptom exacerbation with aerobic exercise at home, attenuated by adjustment of the home exercise program. Conclusions Multimodal, impairment-based PT is safe and associated with diminishing PCS symptoms. This establishes feasibility for future clinical trials to determine viable treatment approaches to reduce symptoms and improve function while avoiding negative repercussions of physical inactivity and premature return to full activity. © 2016 Elsevier Ltd},

abstract = {Background: Concussions are a common pathology in football and multiple misconceptions exist amongst the players and managers. To address these misconceptions, and potentially reduce concussion associated sequela, effective educational interventions need to be developed. However, the current knowledge and attitude status must be ascertained to appropriately develop these interventions. The purpose of this study was to assess the concussion knowledge and attitude of English professional footballers. Methods: Twenty-six participants from one English Football League Championship club completed the study. A mixed methods approach included the Rosenbaum Concussion Knowledge and Attitudes Survey (RoCKAS) and a semi-structured interview. The RoCKAS contains separate knowledge (0-25) and attitude (15-75) scores and was followed by a semi-structured interview consisting of concussion knowledge, attitude, and behavior related questions. Results: The mean score on the RoCKAS knowledge was 16.4 ± 2.9 (range 11-22) and the attitude score was 59.6 ± 8.5 (range 41-71). The interview responses identified inconsistencies between the RoCKAS and the intended behaviors, endorsing multiple concussion misconceptions, and revealed barriers to concussion reporting. Conclusion: The results of this study suggest that Championship Level English footballers have moderate concussion knowledge, safe attitudes, and good concussion symptom recognition when assessed with pen and paper questionnaires. However, within the semi-structured interview many respondents reported unsafe concussion behaviors despite accurately identifying the potential risks. Further, multiple barriers to concussion reporting were identified which included perceived severity of the injury, game situations, and the substitution rule. These findings can help form the foundation of educational interventions to potentially improve concussion reporting behaviors amongst professional footballers. © 2016.},

abstract = {A concussion results from a force to the brain that results in a transient loss of connectivity within the brain. Sport psychiatrists are increasingly called to be part of the concussion team and need to be prepared to manage issues related to concussion and its behavioural sequelae. Objectively, the best evidence available suggests that deficits in attention and/or in balance are the most reliable objective findings that a concussion has occurred. Prognosis after a concussion is generally very good, although a sub-set of patients that are yet well defined seem pre-disposed to delayed recovery. Neither head CT nor MRI are sufficiently sensitive to diagnose the type of injuries that pre-dispose patients to the neurobehavioural sequelae that have been associated with a concussion; confounding this is the finding that many of these signs and symptoms associated with concussion occur in other types of non-head injuries. Brain biomarkers and functional MRI (fMRI) hold promise in both diagnosis and prognosis of concussion, but are still research tools without validated clinical utility at this time. Finally, neurocognitive testing holds promise as a diagnostic criterion to demonstrate injury but, unfortunately, these tests are also limited in their prognostic utility and are of limited value. © 2016 Institute of Psychiatry and John Hopkins University.},

abstract = {Background: Concussions have been associated with elevated musculoskeletal injury risk; however, the influence of unreported and unrecognized concussions has not been investigated. Hypothesis: The purpose of this study was to examine the association between concussion and lower extremity musculoskeletal injury rates across a diverse array of sports among collegiate student-athletes at the conclusion of their athletic career. The hypothesis was that there will be a positive association between athletes who reported a history of concussions and higher rates of lower extremity injuries. Study Design: Cross-sectional study. Level of Evidence: Level 3. Methods: Student-athletes (N = 335; 62.1% women; mean age, 21.2 ± 1.4 years) from 13 sports completed a reliable injury history questionnaire. Respondents indicated the total number of reported, unreported, and potentially unrecognized concussions as well as lower extremity injuries including ankle sprains, knee injuries, and muscle strains. Chi-square analyses were performed to identify the association between concussion and lower extremity injuries. Results: There were significant associations between concussion and lateral ankle sprain (P = 0.012), knee injury (P = 0.002), and lower extremity muscle strain (P = 0.031). There were also significant associations between reported concussions and knee injury (P = 0.003), unreported concussions and knee injury (P = 0.002), and unrecognized concussions and lateral ankle sprain (P = 0.001) and lower extremity muscle strains (P = 0.006), with odds ratios ranging from 1.6 to 2.9. Conclusion: There was a positive association between concussion history and lower extremity injuries (odds ratios, 1.6-2.9 elevated risk) among student-athletes at the conclusion of their intercollegiate athletic careers. Clinical Relevance: Clinicians should be aware of these elevated risks when making return-to-participation decisions and should incorporate injury prevention protocols. © 2016, © 2016 The Author(s).},

abstract = {As participation in women’s soccer continues to grow and the longevity of female athletes’ careers continues to increase, prevention and care for mTBI in women’s soccer has become a major concern for female athletes since the long-term risks associated with a history of mTBI are well documented. Among women’s sports, soccer exhibits among the highest concussion rates, on par with those of men’s football at the collegiate level. Head impact monitoring technology has revealed that 'concussive hits' occurring directly before symptomatic injury are not predictive of mTBI, suggesting that the cumulative effect of repetitive head impacts experienced by collision sport athletes should be assessed. Neuroimaging biomarkers have proven to be valuable in detecting brain changes that occur before neurocognitive symptoms in collision sport athletes. Quantifying the relationship between changes in these biomarkers and head impacts experienced by female soccer athletes may prove valuable to developing preventative measures for mTBI. This study paired functional magnetic resonance imaging with head impact monitoring to track cerebrovascular reactivity changes throughout a season and to test whether the observed changes could be attributed to mechanical loading experienced by female athletes participating in high school soccer. Marked cerebrovascular reactivity changes were observed in female soccer athletes, relative both to non-collision sport control measures and pre-season measures and were localized to fronto-temporal aspects of the brain. These changes persisted 4\textendash5 months after the season ended and recovered by 8 months after the season. Segregation of the total soccer cohort into cumulative loading groups revealed that population-level changes were driven by athletes experiencing high cumulative loads, although athletes experiencing lower cumulative loads still contributed to group changes. The results of this study imply a non-linear relationship between cumulative loading and cerebrovascular changes with a threshold, above which the risk, of injury likely increases significantly.

For each club, we included at least one player and one staff member (manager, medical team member or coach). Results One hundred and sixty-three subjects (37 players and 126 staff members) of 47 clubs were included. For all subjects, the loss of conscious was a symptom of concussion but only 61% could give 3 others symptoms. The risk of a second accident during days after concussion was known by 95%. About primary care, 50% did not look for cervical spine accident just after brain concussion and 22% thought that concussed athletes could finish the game. A majority of our study population (89%) would not leave alone an injured player after the trauma. This study shows some deficiencies in identification of concussion. The questions about primary care indicate some problems that can cause additional accident. © 2016},

Treatment for concussion is an emerging area of focus with investigators seeking to improve outcomes and protect patients from the deleterious short-term and long-term consequences which have been extensively studied and identified. Broadly, current treatment strategies for athletes recovering from concussion have remained largely unchanged since early 2000s. Knowledge of the complex pathophysiology surrounding injury should improve or advance our ability to identify processes which may serve as targets for therapeutic intervention. Clinicians working with athletes recovering from sports-related concussion should have an advanced understanding of the injury cascade and also be aware of the current efforts within the research to treat concussion. In addition, how clinicians use the word "treatment" should be carefully defined and promoted so the patient is aware of the level of intervention and what stage of recovery or healing is being affected by a specific intervention. The purpose of this review is to bring together efforts across disciplines of brain science into 1 platform where clinicians can assimilate this information before making best practices decisions regarding the treatment of patients and athletes under their care. © 2016 Wolters Kluwer Health, Inc.

Limited data exist, however, examining dual-task gait data consistency collected over time in healthy individuals. The study purposes were to: 1) assess the consistency of single-task and dual-task gait balance control measures, 2) determine the minimal detectable change (MDC) of gait balance control measures, and 3) examine the extent to which age and task complexity affect dual-task walking costs in healthy adolescents and young adults. Twenty-four adolescent (mean age=15.5±1.1years) and 21 young adult (mean age=21.2±4.5years) healthy participants completed 5 testing sessions across a two-month period, which involved analyses of gait balance control and temporal-distance variables during single-task and dual-task walking conditions in a motion analysis laboratory. Cronbach's $alpha$ and MDCs were used to determine the consistency of the gait balance control variables and the smallest amount of change required to distinguish true performance from change due to the performance/measurement variability, respectively. Dual-task costs were evaluated to determine the effect of task complexity and age across time using 3-way ANOVAs. Good to excellent test-retest consistency was found for all single-task and dual-task walking (Cronbach's $alpha$ range: 0.764-0.970), with a center-of-mass medial-lateral displacement MDC range of 0.835-0.948cm. Greater frontal plane dual-task costs were observed during more complex secondary tasks (p\<0.001). The results revealed good-excellent consistency across testing sessions for all variables and indicated dual-task costs are affected by task complexity. Thus, healthy controls can be effective comparators when assessing injured subjects. [ABSTRACT FROM AUTHOR]},

abstract = {The relation between resilience and mild traumatic brain injury (TBI) outcome has been theorized but empirical studies have been scarce. This systematic review aimed to describe the research in this area. Electronic databases (Medline, CINAHL, PsychINFO, SPORTdiscus, and PILOTS) were searched from inception to August 2015 for studies in which resilience was measured following TBI. The search terms included ‘TBI’ ‘concussion’ ‘postconcussion’ ‘resilience’ and ‘hardiness’. Inclusion criteria were peer reviewed original research reports published in English, human participants aged 18 years and over with brain injury, and an accepted definition of mild TBI. Hand searching of identified articles was also undertaken. Of the 71 studies identified, five studies were accepted for review. These studies were formally assessed for risk of bias by two independent reviewers. Each study carried a risk of bias, most commonly a detection bias, but none were excluded on this basis. A narrative interpretation of the findings was used because the studies reflected fundamental differences in the conceptualization of resilience. No studies employed a trajectory based approach to measure a resilient outcome. In most cases, the eligible studies assessed trait resilience with a scale and used it as a predictor of outcome (postconcussion symptoms). Three of these studies showed that greater trait resilience was associated with better mild TBI outcomes (fewer symptoms).

abstract = {Emerging research on the long-term impact of concussions on athletes has allowed public recognition of the potentially devastating effects of these and other mild head injuries. Mild traumatic brain injury (mTBI) is a multifaceted disease for which management remains a clinical challenge. Recent pre-clinical and clinical data strongly suggest a destructive synergism between brain temperature elevation and mTBI; conversely, brain hypothermia, with its broader, pleiotropic effects, represents the most potent neuro-protectant in laboratory studies to date. Although well-established in selected clinical conditions, a systemic approach to accomplish regional hypothermia has failed to yield an effective treatment strategy in traumatic brain injury (TBI). Furthermore, although systemic hypothermia remains a potentially valid treatment strategy for moderate to severe TBIs, it is neither practical nor safe for mTBIs. Therefore, selective head-neck cooling may represent an ideal strategy to provide therapeutic benefits to the brain. Optimizing brain temperature management using a National Aeronautics and Space Administration (NASA) spacesuit spinoff head-neck cooling technology before and/or after mTBI in contact sports may represent a sensible, practical, and effective method to potentially enhance recover and minimize post-injury deficits. In this paper, we discuss and summarize the anatomical, physiological, preclinical, and clinical data concerning NASA spinoff head-neck cooling technology as a potential treatment for mTBIs, particularly in the context of contact sports. © 2015 Huan Wang et al., licensee De Gruyter Open.},

abstract = {Using metrics that permit detailed analysis of sway variability, the authors demonstrate the capacity to detect alterations in postural control among youth who sustained concussion. Purpose: The purpose of this study was to evaluate the utility of postural sway variability as a potential assessment to detect altered postural sway in youth with symptoms related to a concussion. Methods: Forty participants (20 who were healthy and 20 who were injured) aged 10 to 16 years were assessed using the Balance Error Scoring System (BESS) and postural sway variability analyses applied to center-of-pressure data captured using a force plate. Results: Significant differences were observed between the 2 groups for postural sway variability metrics but not for the BESS. Specifically, path length was shorter and Sample and Renyi Entropies were more regular for the participants who were injured compared with the participants who were healthy (P \<.05). Conclusion: The results of this study indicate that postural sway variability may be a more valid measure than the BESS to detect postconcussion alterations in postural control in young athletes. © 2015 Wolters Kluwer Health, Inc.},

abstract = {BACKGROUND: Mild traumatic brain injury (mTBI) constitutes 75% of more than 1.5 million traumatic brain injuries annually. There exists no consensus on point-of-care screening for mTBI. The Military Acute Concussion Evaluation (MACE) is a quick and easy test used by the US Army to screen for mTBI; however, its utility in civilian trauma is unclear. It has two parts: a history section and the Standardized Assessment of Concussion (SAC) score (0-30) previously validated in sports injury. As a performance improvement project, our institution sought to evaluate the MACE as a concussion screening tool that could be used by housestaff in a general civilian trauma population. METHODS: From June 2013 to May 2014, patients 18 years to 65 years old with suspected concussion were given the MACE within 72 hours of admission to our urban Level I trauma center. Patients with a positive head computed tomography were excluded. Demographic data and MACE scores were recorded in prospect. Concussion was defined as loss of consciousness and/or posttraumatic amnesia; concussed patients were compared with those nonconcussed. Sensitivity and specificity for each respective MACE score were used to plot a receiver operating characteristic (ROC) curve. An ROC curve area of 0.8 was set as the benchmark for a good screening test to distinguish concussion from nonconcussion. RESULTS: There were 84 concussions and 30 nonconcussed patients. Both groups were similar; however, the concussion group had a lower mean MACE score than the nonconcussed patients. Data analysis demonstrated the sensitivity and specificity of a range of MACE scores used to generate an ROC curve area of only 0.65. CONCLUSION: The MACE showed a lower mean score for individuals with concussion, defined by loss of consciousness and/or posttraumatic amnesia. However, the ROC curve area of 0.65 highly suggests that MACE alone would be a poor screening test for mTBI in a general civilian trauma population. LEVEL OF EVIDENCE: Diagnostic study, level II.

abstract = {Traumatic brain injury (TBI), including concussion, is a public health concern, as it affects over 1.7 million persons in the United States per year. Yet, the diagnosis of TBI, particularly mild TBI (mTBI), can be controversial, as neuroimaging findings can be sparse on conventional magnetic resonance and computed tomography examinations, and when present, often poorly correlate with clinical signs and symptoms. Furthermore, the discussion of TBI, concussion, and head impact exposure is immediately complicated by the many differing opinions of what constitutes each, their respective severities, and how the underlying biomechanics of the inciting head impact might alter the distribution, severity, and prognosis of the underlying brain injury. Advanced imaging methodologies hold promise in improving the sensitivity and detectability of associated imaging biomarkers that might better correlate with patient outcome and prognostication, allowing for improved triage and therapeutic guidance in the setting of TBI, particularly in mTBI. This work will examine the defining symptom complex associated with mTBI and explore changes in cerebral blood flow measured by arterial spin labeling, as a potential imaging biomarker for TBI, and briefly correlate these observations with findings identified by single photon emission computed tomography and positron emission tomography imaging..

abstract = {Objective: Obtaining baseline neuropsychological (NP) data to assist management of sports-related concussion has been considered the standard of care. The validity of this approach has been questioned, with suggestions that post-concussion testing alone will suffice. The present study compared the sensitivity of baseline and normative paradigms in the setting of sports-related concussion. Method: Baseline NP data were collected for 194 Australian rugby league athletes on a brief battery of paper-and-pencil NP tests. During competition, 27 athletes sustaining concussion referred from a sports physician were retested within two days of injury. Twenty-six uninjured controls were assessed at similar intervals. The baseline paradigm was assessed using a reliable change index for pre- and post-concussion scores. The normative paradigm was assessed comparing the post-concussion score to a normative mean. Results: The baseline paradigm was consistently more sensitive to negative change following concussion than the normative paradigm when using continuous data, despite reasonable agreement. However, when data were categorised as 'impaired' or 'not-impaired', using either 68% or 90% confidence intervals, the difference between paradigms failed to reach significance. Comparison of ROC curves for both paradigms found superior overall classification for one test and the composite score using baseline comparison data. Conclusions: Despite being a time and resource intensive process, the baseline paradigm as a repeated-measures design may be more sensitive than the between-subjects design of the normative paradigm for detecting changes following concussion. Further work is required to determine the validity of normative assessment in sports-related concussion. Copyright © Australasian Society for the Study of Brain Impairment 2015.},

Baseline neurocognitive testing was conducted pre-season in Grade 7 and post-season in Grades 8 and 9. Year-end academic grades were documented for Grades 6-9 and 12 (pre-high school to year of school leaving). A mixed model repeated measures ANOVA was conducted to investigate comparative neurocognitive and academic outcomes between the three sub-groups.Results: Compared with controls, both rugby groups were significantly lower on the WISC-III Coding Immediate Recall sub-test. There was a significant interaction effect on the academic measure, with improved scores over time for controls, that was not in evidence for either rugby group.Conclusions: Tentatively, the outcome suggests cognitive vulnerability in association with school level participation in rugby. © 2015 Taylor \& Francis Group, LLC.},

abstract = {Purpose: Approximately 90% of concussions are transient, with symptoms resolving within 10\textendash14 days. However, a minority of patients remain symptomatic several months post-injury, a condition known as post-concussion syndrome (PCS). The treatment of these patients can be challenging. The goal of our study was to assess the utility and cost-effectiveness of neurologic imaging two or more weeks post-injury in a cohort of youth with PCS. Methods: We conducted a retrospective study of 52 pediatric patients with persistent post-concussion symptoms after 3 months. We collected demographics and neuroimaging results obtained greater than 2 weeks post-concussion. Neuroimaging ordered in the first 2 weeks post-concussion was excluded, except to determine the rate of re-imaging. Descriptive statistics and corresponding cost data were collected. Results: Of 52 patients with PCS, 23/52 (44 %) had neuroimaging at least 2 weeks after the initial injury, for a total of 32 diagnostic studies. In summary, 1/19 MRIs (5.3 %), 1/8 CTs (13 %), and 0/5 x-rays (0 %) yielded significant positive findings, none of which altered clinical management. Chronic phase neuroimaging estimated costs from these 52 pediatric patients totaled $129,025. We estimate the cost to identify a single positive finding was $21,000 for head CT and $104,500 for brain MRI. Conclusions: In this cohort of pediatric PCS patients, brain imaging in the chronic phase (defined as more than 2 weeks after concussion) was pursued in almost half the study sample, had low diagnostic yield, and had poor cost-effectiveness. Based on these results, outpatient management of pediatric patients with long-term post-concussive symptoms should rarely include repeat neuroimaging beyond the acute phase. © 2015, Springer-Verlag Berlin Heidelberg.},

abstract = {Background: Sports are a major cause of concussions, and little is known about the symptom experience and health-related quality of life (HRQL) in children who remain symptomatic for over 3 months following such head injuries. Methods: A cross-sectional study of children aged 10-18 years was performed who were referred to the Neurosurgery Clinic at our centre following a head injury. Symptom experience was measured using the modified Concussion Symptom Scale, and HRQL was measured using the Pediatric Quality of Life Inventory (PedsQL). The Immediate Postconcussion Assessment and Cognitive Test (ImPACT) was administered to assess neurocognitive and neurobehavioural sequelae. Results: Symptoms with the highest mean symptom scores on a Likert scale of 0-6 in 35 children at the time of assessment included headaches (3.1), poor concentration (2.7), memory problems (2.1), fatigue (2.1) and sensitivity to noise (2.0). Compared with normative data, children in this study had ImPACT summary scores between the 28th and 38th percentiles and a comparably low Cognitive Efficiency Index score. Mean scores for females were consistently statistically significantly lower (p \< 0.05) than for males across all of the HRQL domains. Trouble falling asleep and memory problems explained 62% of the variance in the PedsQL total scores. Conclusions: Children continue to experience many symptoms at least 3 months following sport-related head injuries that significantly impact their HRQL and neurocognitive abilities. © 2015 S.

Findings demonstrate that mTBI management information in Australasia needs urgent revision, and evaluation in other countries is strongly advised.

abstract = {Context: Chronic traumatic encephalopathy (CTE) is a rare progressive neurologic disorder that can manifest as a combination of cognitive, mood and behavioral, and neurologic symptoms. Despite clinically apparent symptoms, there is no imaging or other diagnostic test that can confirm diagnosis in living subjects. Diagnosis can only be confirmed postmortem by specific histopathologic features within the brain tissue identified on autopsy. CTE represents a unique tauopathy that is distinct from other neurodegenerative diseases. Evidence Acquisition: PubMed was searched from 1990 to 2013 for sport concussion and chronic traumatic encephalopathy. Articles were also identified from bibliographies of recent reviews and consensus statements. Study Design: Clinical review. Level of Evidence: Level 5. Results: Although CTE is postulated to occur as a result of repetitive mild traumatic brain injury, the specific etiology and risk factors have not yet been elucidated, and postmortem diagnosis makes causality difficult to determine. Conclusion: When counseling athletes and families about the potential association of recurrent concussions and the development of CTE, discussion of proper management of concussion is cornerstone. Unfortunately, to date, there is no equipment that can prevent concussions; however, rule changes and legislation may decrease the risk. It is imperative that return to play is medically supervised by a provider trained in the management of concussion and begins only once symptoms have resolved. In addition, athletes with permanent symptoms should be retired from contact sport. © 2014 The Author(s).},

Evidence based diagnostic guidelines have been established,1 but the diagnosis and treatment are largely grounded in clinical decision-making. Clinical and research issues around sports concussion have even reached the levels of government policy with the White House. At the moderate to severe range of traumatic brain injury, neuroimaging provides well-established, objective pathoanatomical biomarkers of the injury. In contrast, conventional neuroimaging findings in mTBI are typically absent. The cognitive and neurobehavioral symptoms of mTBI overlap with any number of neurologic or psychiatric disorders, providing no definitive marker of injury or for tracking injury effects. Reliable biomarkers of mTBI could lead to better clinical decision-making and potential treatments. Deformation-based biomechanical studies of mTBI have shown the thalamus is situated in a particularly vulnerable zone. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

(The following abstract of the original article appeared in record [rid]2010-23062-009[/rid]). Concussive head injury opens a temporary window of brain vulnerability due to the impairment of cellular energetic metabolism. As experimentally demonstrated, a second mild injury occurring during this period can lead to severe brain damage, a condition clinically described as the second impact syndrome. To corroborate the validity of proton magnetic resonance spectroscopy in monitoring cerebral metabolic changes following mild traumatic brain injury, apart from the magnetic field strength (1.5 or 3.0 T) and mode of acquisition, we undertook a multicentre prospective study in which a cohort of 40 athletes suffering from concussion and a group of 30 control healthy subjects were admitted. Athletes (aged 16\textendash35 years) were recruited and examined at three different institutions between September 2007 and June 2009. They underwent assessment of brain metabolism at 3, 15, 22 and 30 days post-injury through proton magnetic resonance spectroscopy for the determination of N-acetylaspartate, creatine and choline-containing compounds. Values of these representative brain metabolites were compared with those observed in the group of non-injured controls. Comparison of spectroscopic data, obtained in controls using different field strength and/or mode of acquisition, did not show any difference in the brain metabolite ratios. Athletes with concussion exhibited the most significant alteration of metabolite ratios at Day 3 post-injury (N-acetylaspartate/creatine: −17.6%, N-acetylaspartate/choline: −21.4%; P \< 0.001 with respect to controls). On average, metabolic disturbance gradually recovered, initially in a slow fashion and, following Day 15, more rapidly. At 30 days post-injury, all athletes showed complete recovery, having metabolite ratios returned to values detected in controls. Athletes self-declared symptom clearance between 3 and 15 days after concussion. Results indicate that N-acetylaspartate determination by proton magnetic resonance spectroscopy represents a non-invasive tool to accurately measure changes in cerebral energy metabolism occurring in mild traumatic brain injury. In particular, this metabolic evaluation may significantly improve, along with other clinical assessments, the management of athletes suffering from concussion. Further studies to verify the effects of a second concussive event occurring at different time points of the recovery curve of brain metabolism are needed.

abstract = {INTRODUCTION: Problems with balance and dizziness are one of the most common complaints of individuals who have experienced a brain injury and are reported in up to 90% of cases. Despite the ubiquity of vestibular disturbance in this population, there remains a dearth of research on the interaction between physiological and cognitive systems responsible for maintaining balance. PURPOSE: The purpose of this article is to review studies on the interaction of physiological and cognitive processes required to maintain balance that may aide assessment and recovery of balance disturbance in patients with brain injury. SUMMARY: This article provides a review of research on the role of higher order cognitive processes in maintaining balance and rational for further inclusion of neurocognitive measures in the assessment of vestibular disturbance. CONCLUSION: Greater inclusion of neurocognitive measures in assessment of vestibular disturbance provides a method of assessment containing increased ecological validity compared to traditional assessments, better prepares patients for discharge, and may reduce the incidence of future injury.},

abstract = {The purpose of this study was to: (1) Establish whether or not specific rehabilitation for mild brain injury is effective for return to work; and (2) compare the efficacy of an impairment-focused model of treatment versus an early education approach in respect to ability to return to work. Two different approaches to intervention and treatment for those with a suspected concussion from a work-related injury were utilised by an urban, interdisciplinary, outpatient rehabilitation facility. The first approach, Group Treatment (GT), provided minimal early education at time of initial intake, emphasising an extensive group-focused interdisciplinary assessment and treatment. The second approach, Individualized Education and Treatment, (IET) emphasised early education, instead coupled with specific individualised services. Both groups received employment services. Post-discharge, GT ( N = 26) resulted in 46% ( n = 12) of individuals returning to competitive employment, while IET ( N = 23) resulted in 78% ( n = 18) of individuals returning to competitive employment. An asset-oriented early individualised educational approach appears to be a more effective for employment re-engagement. ABSTRACT FROM AUTHOR},

abstract = {Primary objective: To evaluate low-level to complex information processing using visual electrophysiology and to examine the latter's prognostic value in regards to vocational outcome in persons having sustained a mild traumatic brain injury (mTBI). Research design/methods: Event-related potentials (ERPs) were recorded to pattern-reversal, simple motion, texture segregation and cognitive oddball paradigms from 17 participants with symptomatic mTBI at onset of specialized clinical intervention and from 15 normal controls. The relationship between abnormal electrophysiology and post-intervention return to work status was also examined. Main outcomes and results: Participants with mTBI showed a statistically significant (p \< .05) amplitude reduction for cognitive ERPs and delayed latencies for texture (p \< .05) and cognitive paradigms (p \< .005) compared to controls. Furthermore, participants with mTBI presenting texture or cognitive ERP latency delays upon admission were at significantly (p \< .01) greater risk of negative vocational outcome than mTBI participants with normal electrophysiology. Conclusions: The findings suggest that individuals with symptomatic mTBI can present selective deficits in complex visual information processing that could interfere with vocational outcome. ERP paradigms such as those employed in this study thus show potential for evaluating outcome prognosis and merit further study. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

Systematic reviews of intervention strategies have indicated that psychological approaches to treatment of MTBI, such as early education and support, are more effective than any form of drug treatment.
