abstract = {This research explored associations between helmet use and head injuries in snowsports by investigating reported snowsport injuries in Western Canada from 2008-2009 to 2012-2013. The key finding was that increased helmet use (from 69% to 80%) was not associated with a reduction in reported head injuries. Over the study period, the average rate of reported head injuries was 0.2/1000 skier visits, with a statistically significant variation ( P \< 0.001). The line of best fit showed an non-significant upward trend ( P = 0.13). Lacerations were the only subcategory of head injuries that decreased significantly with helmet use. A higher proportion of people who reported a head injury were wearing a helmet than for injuries other than to the head. Skiers were more likely to report a head injury when wearing a helmet than snowboarders ( P \< 0.001 cf. P = 0.22). There were significant differences in characteristics of helmet and non-helmet wearers. Helmet wearers were more likely to be: young adults ( P \< 0.001); beginner/novices ( P = 0.004); and snowboarders ( P \< 0.001), but helmet wearing was not associated with gender ( P = 0.191). Further research is needed to explore the possible reasons for the failure of helmets to reduce head injuries, for example, increased reporting of head injuries and increased risk-taking combined with over-rating of the helmets' protection.},

abstract = {OBJECTIVES: To describe determinants of head impact magnitudes between various play aspects in high school football. METHODS: Thirty-two high school American football players wore Head Impact Telemetry System instrumented helmets to capture head impact magnitude (linear acceleration, rotational acceleration, and Head Impact Technology severity profile [HITsp]). We captured and analyzed video from 13 games (n = 3888 viewable head impacts) to determine the following play aspects: quarter, impact cause, play type, closing distance, double head impact, player's stance, player's action, direction of gaze, athletic readiness, level of anticipation, player stationary, ball possession, receiving ball, and snapping ball. We conducted random intercepts general linear mixed models to assess the differences in head impact magnitude between play aspects ($alpha$ = 0.05). RESULTS: The following aspects resulted in greater head impact magnitude: impacts during the second quarter (HITsp: P= .03); contact with another player (linear, rotational, HITsp: P \< .001); initial head impact when the head is struck twice (linear, rotational, HITsp: P \< .001); longer closing distances, especially when combined with a 3-point stance or when being struck in the head (linear: P = .03); the 2-point stance (linear, rotational, HITsp: P \< .001); and offensive linemen not snapping the ball compared with those snapping the ball (rotational: P = .02, HITsp: P = .02). CONCLUSIONS: Preventing head impacts caused by contact with another player may reduce head impact magnitude in high school football. Rule or coaching changes that reduce collisions after long closing distances, especially when combined with the 3-point stance or when a player is being struck in the head, should be considered.

abstract = {Objective: To examine the influence of age, sex, attention-deficit hyperactivity disorder (ADHD) status, previous history of concussion, and days since injury on postconcussion postural control assessment in adolescents who have suffered a concussion. Design: Prospective cohort study. Setting: Hospital-based outpatient clinic. Participants: Seventy-one participants (42 males; 29 females) with mean age 14.14 ± 2.44. Independent Variables: Age, sex, previous concussion history, ADHD status, total and severity of postconcussion symptoms, and days since injury. Main Outcome Measures: Total Balance Error Scoring System score, path length, center-of-pressure (COP) area, sample entropy, and Romberg quotient. Results: Pearson product-moment correlation coefficients were calculated to test for potential associations between the continuous participant characteristics and the postural control variables. Spearman correlation was used to test the association between symptom severity and the postural control variables. Standard multiple regression was used to model the extent to which participant characteristics accounted for the variance in the postural sway variables. Age was significantly associated with all of the postural sway variables except COP area for the eyes open condition and sample entropy in the anterior-posterior direction for the eyes closed condition. Sex, ADHD status, and previous concussion history did not significantly predict postural control scores. Conclusions: Age significantly influences scores on common postconcussion postural control assessments. Clinical Relevance: This study demonstrates that age is a critical factor that needs to be accounted for to improve the clinical appropriateness and utility of current postconcussion postural control assessments.

abstract = {Objective: The objective of this paper is to review existing literature surrounding the utility of the King-Devick test which is a commonly used sideline assessment tool for sport-related concussions. Methods: A review of the literature was performed using MEDLINE, CINHAL, and SportDiscus databases. The search was performed from the beginning of the record through November 16th, 2015. Results: This search strategy yielded 27 articles from aforementioned databases. Further searching in The Cochrane Library with King-Devick AND Concuss* search terms yielded one additional article, summing a total of 28 articles. After removal of duplicates and implementation of the inclusion/exclusion criteria, 8 articles for extensively reviewed. Conclusion: This narrative review suggests that the King-Devick test is an efficient sideline assessment tool for sport-related concussions. However, we recommend that the King-Devick should be used as a sideline screening tool, not a concussion diagnosis tool at this time. A proper baseline time including multiple tests may be recommended to negate the learning affect and to have a reliable baseline in which to measure from for future reference. A three second difference appears appropriate to identify the possibility of concussion and to remove an athlete from play. At this time, the athlete should be monitored and further evaluated as symptoms are sometimes delayed. We suggest that further research may be useful to better determine the efficacy of the K-D test in detecting concussions across a broader range of athletes and sports. We also suggest further research may investigate the K-D test a potential return-to-play tool for clinicians and medical personnel.},

abstract = {Background: Sports-related concussions (SRCs) have gained increased societal interest in the past decade. The National Collegiate Athletic Association (NCAA) has implemented legislation and rule changes to decrease the incidence and risk of head injury impacts. The “targeting” rule forbids initiating contact with the crown of a helmet and targeting defenseless players in the head and neck area; however, there are concerns that this rule change has unintentionally led to an increased incidence of lower extremity injuries. Purpose/Hypothesis: The purpose of this study was to evaluate the change in lower extremity injury rates in NCAA football during the 2009-2010 to 2014-2015 seasons. We hypothesized that the lower extremity injury rate has increased across the time period. Study Design: Descriptive epidemiology study. Methods: Sixty-eight NCAA football programs provided 153 team-seasons of data to the NCAA Injury Surveillance Program. Lower extremity injuries (ie, hip/groin, upper leg/thigh, knee, lower leg/Achilles, foot/toes) and SRCs sustained during NCAA football games were examined. We calculated injury rates per 1000 athlete-exposures (AEs) for lower extremity injuries and SRCs. Rate ratios (RRs) compared injury rates between the 2009-2010 to 2011-2012 and 2012-2013 to 2014-2015 seasons. Results: Overall, 2400 lower extremity injuries were reported during the 2009-2010 to 2014-2015 seasons; most were to the knee (33.6%) and ankle (28.5%) and caused by player contact (59.2%). The lower extremity injury rate increased in 2012-2013 to 2014-2015 compared with 2009-2010 to 2011-2012 (23.55 vs 20.45/1000 AEs, respectively; RR, 1.15; 95% CI, 1.06-1.25). This finding was retained when restricted to injuries due to player contact (RR, 1.19; 95% CI, 1.07-1.32) but not for injuries due to noncontact/overuse (RR, 0.96; 95% CI, 0.80-1.14). When examining player contact injury rates by anatomic site, only ankle injuries had an increase (RR, 1.36; 95% CI, 1.13-1.64). The SRC rate also increased in 2012-2013 to 2014-2015 compared with 2009-2010 to 2011-2012 (3.52 vs 2.63/1000 AEs, respectively; RR, 1.34; 95% CI, 1.08-1.66). Conclusion: The lower extremity injury rate has increased in NCAA football athletes. Similarly, SRC rates have increased, although this may be caused by concurrent policies related to better education, identification, and management. Targeting rule changes may be contributing to increased rates of player contact\textendashrelated ankle injuries. Alongside continued surveillance research to examine longitudinal time trends, more in-depth individual-level examinations of how targeting rule changes influence coaching and player behaviors are warranted.

abstract = {Purpose: The decision regarding return to activity (RTA) after mild traumatic brain injuries/concussion is one of the most difficult and controversial areas in concussion management, particularly for youth. This study investigated how youth with postconcussion syndrome (PCS) are affected by exertion and whether standardized exertion testing using the McMaster All-Out Progressive Continuous Cycling Test can contribute to clinical decision making for safe RTA. Methods: Fifty-four youth (8.5-18.3 yr) with a previously confirmed concussion participated in the study. Each participant performed exertion testing on a cycle ergometer and completed a Postconcussion Symptom scale at the following time points: before exertion (baseline), 5 and 30 min, and 24 h after exertion. A modified Postconcussion Symptom scale was administered at 2-min intervals during exertion. Results: Participants had a mean T SD symptom duration of 6.3 T 6.9 months after the most recent concussive injury, with a median of 4.1 months (range, 0.7-35 months). Sixty-three percent of participants had symptoms during exertion testing. Symptom profile (number and severity) significantly affected perception of exertion at 50% peak mechanical power. During acute assessment of symptoms (30-min after exertion), headache (P = 0.39), nausea (P = 0.63), and dizziness (P = 0.35) did not change. However, both the number and severity of symptoms significantly improved over 24 h, with 56.8% of youth showing improvements. The time from the most recent injury had a significant effect on the symptom score at baseline, 30 min after exertion, and 24 h after exertion. Conclusions: Exertion testing has an important role in the evaluation of symptoms and readiness to RTA, particularly in youth who are slow to recover. Overall, controlled exertion seemed to lesson symptoms for most youth. ABSTRACT FROM AUTHOR},

Design: A prospective cross-sectional cohort study. Setting: Level I trauma center. Participants: Adults (N=242) with TBI of various severity. Interventions: Not applicable. Main Outcome Measures: Extended Glasgow Outcome Scale, return to work (RTW), Head Injury Symptom Checklist, and Hospital Anxiety and Depression Scale. Results: In 67% of the patients, complaints were present; 22% were anxious, and 18% were depressed. The frequency of complaints increased significantly with injury severity, in contrast to anxiety and depression. Frequencies of patients with anxiety and depression (9% and 5%) were lower with complete RTW than with incomplete RTW (42% and 37%; P\<.001). Patients with minor TBI with complaints were more anxious (50% vs 27%; P\<.05) and depressed (46% vs 23%; P\<.05) compared with patients with other severity categories and patients with incomplete RTW (67% vs 36% and 60% vs 30%, respectively). A higher percentage of women with minor TBI were depressed (45% vs 13%; P=.01) and had incomplete RTW (50% vs 18%; P\<.05) compared with men. Multiple regression analysis showed that injury severity, complaints, anxiety, and depression were all predictive of RTW (explained variance 45%). In all severity categories, anxiety and depression were predictive of RTW, complaints, and sex only for minor TBI. Conclusions: Anxiety and depression are related to vocational outcome after TBI, with a different profile in the minor TBI category, partly due to sex differences. Copyright \&y\& Elsevier},

The line of best fit showed an non-significant upward trend ( P = 0.13). Lacerations were the only subcategory of head injuries that decreased significantly with helmet use. A higher proportion of people who reported a head injury were wearing a helmet than for injuries other than to the head. Skiers were more likely to report a head injury when wearing a helmet than snowboarders ( P \< 0.001 cf. P = 0.22). There were significant differences in characteristics of helmet and non-helmet wearers. Helmet wearers were more likely to be: young adults ( P \< 0.001); beginner/novices ( P = 0.004); and snowboarders ( P \< 0.001), but helmet wearing was not associated with gender ( P = 0.191). Further research is needed to explore the possible reasons for the failure of helmets to reduce head injuries, for example, increased reporting of head injuries and increased risk-taking combined with over-rating of the helmets' protection.},

METHODS: Thirty-two high school American football players wore Head Impact Telemetry System instrumented helmets to capture head impact magnitude (linear acceleration, rotational acceleration, and Head Impact Technology severity profile [HITsp]). We captured and analyzed video from 13 games (n = 3888 viewable head impacts) to determine the following play aspects: quarter, impact cause, play type, closing distance, double head impact, player's stance, player's action, direction of gaze, athletic readiness, level of anticipation, player stationary, ball possession, receiving ball, and snapping ball. We conducted random intercepts general linear mixed models to assess the differences in head impact magnitude between play aspects ($alpha$ = 0.05). RESULTS: The following aspects resulted in greater head impact magnitude: impacts during the second quarter (HITsp: P= .03); contact with another player (linear, rotational, HITsp: P \< .001); initial head impact when the head is struck twice (linear, rotational, HITsp: P \< .001); longer closing distances, especially when combined with a 3-point stance or when being struck in the head (linear: P = .03); the 2-point stance (linear, rotational, HITsp: P \< .001); and offensive linemen not snapping the ball compared with those snapping the ball (rotational: P = .02, HITsp: P = .02). CONCLUSIONS: Preventing head impacts caused by contact with another player may reduce head impact magnitude in high school football. Rule or coaching changes that reduce collisions after long closing distances, especially when combined with the 3-point stance or when a player is being struck in the head, should be considered.

abstract = {Objective: The objective of this paper is to review existing literature surrounding the utility of the King-Devick test which is a commonly used sideline assessment tool for sport-related concussions. Methods: A review of the literature was performed using MEDLINE, CINHAL, and SportDiscus databases. The search was performed from the beginning of the record through November 16th, 2015. Results: This search strategy yielded 27 articles from aforementioned databases. Further searching in The Cochrane Library with King-Devick AND Concuss* search terms yielded one additional article, summing a total of 28 articles. After removal of duplicates and implementation of the inclusion/exclusion criteria, 8 articles for extensively reviewed. Conclusion: This narrative review suggests that the King-Devick test is an efficient sideline assessment tool for sport-related concussions. However, we recommend that the King-Devick should be used as a sideline screening tool, not a concussion diagnosis tool at this time. A proper baseline time including multiple tests may be recommended to negate the learning affect and to have a reliable baseline in which to measure from for future reference. A three second difference appears appropriate to identify the possibility of concussion and to remove an athlete from play. At this time, the athlete should be monitored and further evaluated as symptoms are sometimes delayed. We suggest that further research may be useful to better determine the efficacy of the K-D test in detecting concussions across a broader range of athletes and sports. We also suggest further research may investigate the K-D test a potential return-to-play tool for clinicians and medical personnel.},

abstract = {Background: Sports-related concussions (SRCs) have gained increased societal interest in the past decade. The National Collegiate Athletic Association (NCAA) has implemented legislation and rule changes to decrease the incidence and risk of head injury impacts. The “targeting” rule forbids initiating contact with the crown of a helmet and targeting defenseless players in the head and neck area; however, there are concerns that this rule change has unintentionally led to an increased incidence of lower extremity injuries. Purpose/Hypothesis: The purpose of this study was to evaluate the change in lower extremity injury rates in NCAA football during the 2009-2010 to 2014-2015 seasons. We hypothesized that the lower extremity injury rate has increased across the time period. Study Design: Descriptive epidemiology study. Methods: Sixty-eight NCAA football programs provided 153 team-seasons of data to the NCAA Injury Surveillance Program. Lower extremity injuries (ie, hip/groin, upper leg/thigh, knee, lower leg/Achilles, foot/toes) and SRCs sustained during NCAA football games were examined. We calculated injury rates per 1000 athlete-exposures (AEs) for lower extremity injuries and SRCs. Rate ratios (RRs) compared injury rates between the 2009-2010 to 2011-2012 and 2012-2013 to 2014-2015 seasons. Results: Overall, 2400 lower extremity injuries were reported during the 2009-2010 to 2014-2015 seasons; most were to the knee (33.6%) and ankle (28.5%) and caused by player contact (59.2%). The lower extremity injury rate increased in 2012-2013 to 2014-2015 compared with 2009-2010 to 2011-2012 (23.55 vs 20.45/1000 AEs, respectively; RR, 1.15; 95% CI, 1.06-1.25). This finding was retained when restricted to injuries due to player contact (RR, 1.19; 95% CI, 1.07-1.32) but not for injuries due to noncontact/overuse (RR, 0.96; 95% CI, 0.80-1.14). When examining player contact injury rates by anatomic site, only ankle injuries had an increase (RR, 1.36; 95% CI, 1.13-1.64). The SRC rate also increased in 2012-2013 to 2014-2015 compared with 2009-2010 to 2011-2012 (3.52 vs 2.63/1000 AEs, respectively; RR, 1.34; 95% CI, 1.08-1.66). Conclusion: The lower extremity injury rate has increased in NCAA football athletes. Similarly, SRC rates have increased, although this may be caused by concurrent policies related to better education, identification, and management. Targeting rule changes may be contributing to increased rates of player contact\textendashrelated ankle injuries. Alongside continued surveillance research to examine longitudinal time trends, more in-depth individual-level examinations of how targeting rule changes influence coaching and player behaviors are warranted.

abstract = {Purpose: The decision regarding return to activity (RTA) after mild traumatic brain injuries/concussion is one of the most difficult and controversial areas in concussion management, particularly for youth. This study investigated how youth with postconcussion syndrome (PCS) are affected by exertion and whether standardized exertion testing using the McMaster All-Out Progressive Continuous Cycling Test can contribute to clinical decision making for safe RTA. Methods: Fifty-four youth (8.5-18.3 yr) with a previously confirmed concussion participated in the study. Each participant performed exertion testing on a cycle ergometer and completed a Postconcussion Symptom scale at the following time points: before exertion (baseline), 5 and 30 min, and 24 h after exertion. A modified Postconcussion Symptom scale was administered at 2-min intervals during exertion. Results: Participants had a mean T SD symptom duration of 6.3 T 6.9 months after the most recent concussive injury, with a median of 4.1 months (range, 0.7-35 months). Sixty-three percent of participants had symptoms during exertion testing. Symptom profile (number and severity) significantly affected perception of exertion at 50% peak mechanical power. During acute assessment of symptoms (30-min after exertion), headache (P = 0.39), nausea (P = 0.63), and dizziness (P = 0.35) did not change. However, both the number and severity of symptoms significantly improved over 24 h, with 56.8% of youth showing improvements. The time from the most recent injury had a significant effect on the symptom score at baseline, 30 min after exertion, and 24 h after exertion. Conclusions: Exertion testing has an important role in the evaluation of symptoms and readiness to RTA, particularly in youth who are slow to recover. Overall, controlled exertion seemed to lesson symptoms for most youth. ABSTRACT FROM AUTHOR},

Design: A prospective cross-sectional cohort study. Setting: Level I trauma center. Participants: Adults (N=242) with TBI of various severity. Interventions: Not applicable. Main Outcome Measures: Extended Glasgow Outcome Scale, return to work (RTW), Head Injury Symptom Checklist, and Hospital Anxiety and Depression Scale. Results: In 67% of the patients, complaints were present; 22% were anxious, and 18% were depressed. The frequency of complaints increased significantly with injury severity, in contrast to anxiety and depression. Frequencies of patients with anxiety and depression (9% and 5%) were lower with complete RTW than with incomplete RTW (42% and 37%; P\<.001). Patients with minor TBI with complaints were more anxious (50% vs 27%; P\<.05) and depressed (46% vs 23%; P\<.05) compared with patients with other severity categories and patients with incomplete RTW (67% vs 36% and 60% vs 30%, respectively). A higher percentage of women with minor TBI were depressed (45% vs 13%; P=.01) and had incomplete RTW (50% vs 18%; P\<.05) compared with men. Multiple regression analysis showed that injury severity, complaints, anxiety, and depression were all predictive of RTW (explained variance 45%). In all severity categories, anxiety and depression were predictive of RTW, complaints, and sex only for minor TBI. Conclusions: Anxiety and depression are related to vocational outcome after TBI, with a different profile in the minor TBI category, partly due to sex differences. Copyright \&y\& Elsevier},

abstract = {Objective: The objective of this paper is to review existing literature surrounding the utility of the King-Devick test which is a commonly used sideline assessment tool for sport-related concussions. Methods: A review of the literature was performed using MEDLINE, CINHAL, and SportDiscus databases. The search was performed from the beginning of the record through November 16th, 2015. Results: This search strategy yielded 27 articles from aforementioned databases. Further searching in The Cochrane Library with King-Devick AND Concuss* search terms yielded one additional article, summing a total of 28 articles. After removal of duplicates and implementation of the inclusion/exclusion criteria, 8 articles for extensively reviewed. Conclusion: This narrative review suggests that the King-Devick test is an efficient sideline assessment tool for sport-related concussions. However, we recommend that the King-Devick should be used as a sideline screening tool, not a concussion diagnosis tool at this time. A proper baseline time including multiple tests may be recommended to negate the learning affect and to have a reliable baseline in which to measure from for future reference. A three second difference appears appropriate to identify the possibility of concussion and to remove an athlete from play. At this time, the athlete should be monitored and further evaluated as symptoms are sometimes delayed. We suggest that further research may be useful to better determine the efficacy of the K-D test in detecting concussions across a broader range of athletes and sports. We also suggest further research may investigate the K-D test a potential return-to-play tool for clinicians and medical personnel.},

abstract = {Background: Sports-related concussions (SRCs) have gained increased societal interest in the past decade. The National Collegiate Athletic Association (NCAA) has implemented legislation and rule changes to decrease the incidence and risk of head injury impacts. The “targeting” rule forbids initiating contact with the crown of a helmet and targeting defenseless players in the head and neck area; however, there are concerns that this rule change has unintentionally led to an increased incidence of lower extremity injuries. Purpose/Hypothesis: The purpose of this study was to evaluate the change in lower extremity injury rates in NCAA football during the 2009-2010 to 2014-2015 seasons. We hypothesized that the lower extremity injury rate has increased across the time period. Study Design: Descriptive epidemiology study. Methods: Sixty-eight NCAA football programs provided 153 team-seasons of data to the NCAA Injury Surveillance Program. Lower extremity injuries (ie, hip/groin, upper leg/thigh, knee, lower leg/Achilles, foot/toes) and SRCs sustained during NCAA football games were examined. We calculated injury rates per 1000 athlete-exposures (AEs) for lower extremity injuries and SRCs. Rate ratios (RRs) compared injury rates between the 2009-2010 to 2011-2012 and 2012-2013 to 2014-2015 seasons. Results: Overall, 2400 lower extremity injuries were reported during the 2009-2010 to 2014-2015 seasons; most were to the knee (33.6%) and ankle (28.5%) and caused by player contact (59.2%). The lower extremity injury rate increased in 2012-2013 to 2014-2015 compared with 2009-2010 to 2011-2012 (23.55 vs 20.45/1000 AEs, respectively; RR, 1.15; 95% CI, 1.06-1.25). This finding was retained when restricted to injuries due to player contact (RR, 1.19; 95% CI, 1.07-1.32) but not for injuries due to noncontact/overuse (RR, 0.96; 95% CI, 0.80-1.14). When examining player contact injury rates by anatomic site, only ankle injuries had an increase (RR, 1.36; 95% CI, 1.13-1.64). The SRC rate also increased in 2012-2013 to 2014-2015 compared with 2009-2010 to 2011-2012 (3.52 vs 2.63/1000 AEs, respectively; RR, 1.34; 95% CI, 1.08-1.66). Conclusion: The lower extremity injury rate has increased in NCAA football athletes. Similarly, SRC rates have increased, although this may be caused by concurrent policies related to better education, identification, and management. Targeting rule changes may be contributing to increased rates of player contact\textendashrelated ankle injuries. Alongside continued surveillance research to examine longitudinal time trends, more in-depth individual-level examinations of how targeting rule changes influence coaching and player behaviors are warranted.

abstract = {Purpose: The decision regarding return to activity (RTA) after mild traumatic brain injuries/concussion is one of the most difficult and controversial areas in concussion management, particularly for youth. This study investigated how youth with postconcussion syndrome (PCS) are affected by exertion and whether standardized exertion testing using the McMaster All-Out Progressive Continuous Cycling Test can contribute to clinical decision making for safe RTA. Methods: Fifty-four youth (8.5-18.3 yr) with a previously confirmed concussion participated in the study. Each participant performed exertion testing on a cycle ergometer and completed a Postconcussion Symptom scale at the following time points: before exertion (baseline), 5 and 30 min, and 24 h after exertion. A modified Postconcussion Symptom scale was administered at 2-min intervals during exertion. Results: Participants had a mean T SD symptom duration of 6.3 T 6.9 months after the most recent concussive injury, with a median of 4.1 months (range, 0.7-35 months). Sixty-three percent of participants had symptoms during exertion testing. Symptom profile (number and severity) significantly affected perception of exertion at 50% peak mechanical power. During acute assessment of symptoms (30-min after exertion), headache (P = 0.39), nausea (P = 0.63), and dizziness (P = 0.35) did not change. However, both the number and severity of symptoms significantly improved over 24 h, with 56.8% of youth showing improvements. The time from the most recent injury had a significant effect on the symptom score at baseline, 30 min after exertion, and 24 h after exertion. Conclusions: Exertion testing has an important role in the evaluation of symptoms and readiness to RTA, particularly in youth who are slow to recover. Overall, controlled exertion seemed to lesson symptoms for most youth. ABSTRACT FROM AUTHOR},

abstract = {Abstract: Objectives: To investigate the relation of postconcussive complaints, anxiety, and depression with vocational outcome in patients with traumatic brain injury (TBI) of various severities and to assess sex differences. Design: A prospective cross-sectional cohort study. Setting: Level I trauma center. Participants: Adults (N=242) with TBI of various severity. Interventions: Not applicable. Main Outcome Measures: Extended Glasgow Outcome Scale, return to work (RTW), Head Injury Symptom Checklist, and Hospital Anxiety and Depression Scale. Results: In 67% of the patients, complaints were present; 22% were anxious, and 18% were depressed. The frequency of complaints increased significantly with injury severity, in contrast to anxiety and depression. Frequencies of patients with anxiety and depression (9% and 5%) were lower with complete RTW than with incomplete RTW (42% and 37%; P\<.001). Patients with minor TBI with complaints were more anxious (50% vs 27%; P\<.05) and depressed (46% vs 23%; P\<.05) compared with patients with other severity categories and patients with incomplete RTW (67% vs 36% and 60% vs 30%, respectively). A higher percentage of women with minor TBI were depressed (45% vs 13%; P=.01) and had incomplete RTW (50% vs 18%; P\<.05) compared with men. Multiple regression analysis showed that injury severity, complaints, anxiety, and depression were all predictive of RTW (explained variance 45%). In all severity categories, anxiety and depression were predictive of RTW, complaints, and sex only for minor TBI. Conclusions: Anxiety and depression are related to vocational outcome after TBI, with a different profile in the minor TBI category, partly due to sex differences. Copyright \&y\& Elsevier},
