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 = {Neurocognitive test batteries are commonly used tools for concussion assessments in the medical professions. Administered at baseline and post-injury these tests provide information on a patient's neurocognitive ability during the recovery and return-to-activity phases. In athletics, student-athletes usually take the baseline exam as a group in a computer lab prior to the season beginning. If a medical professional believes an individual has sustained a possible concussion, they will retest them and compare their post-injury and baseline results. A deficit in one of more areas of the neurocognitive test may be indicative of a possible concussion. The purpose of this study was to examine whether or not there was a difference in neurocognitive test scores from Concussion Vital Signs when tested under two different conditions: "lights out" and with distractions. Our study was a randomized control trial performed at a Midwestern NCAA, "mid-major" Division I Institution. The subjects were 15 college-aged students with an overall mean age of 19 years (...1.2). There were seven females (mean age was 19 ± 0.77) and eight males (mean age was 20 ± 1.2). A paired t-test was used to determine if a difference in the neurocognitive test section scores between the conditions existed. On three of the ten test sections, there was a statistically significant difference between the baseline and distraction condition. On four of the ten test sections between baseline and the lights out condition for males, but not for females. Testing should be done in a quiet room, with distractions minimized, as distraction hinders focus and performance. The results of this study indicate males may have a more difficult time concentrating while taking neurocognitive tests than females. Administering neurocognitive testing in a quiet, well-lit room is the best condition for the patient to take these concussion-related tests. ABSTRACT FROM AUTHOR},

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 = {The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is reported to possess variable reliability potentially due to a variety of factors, including mood. This study examined the influence of mood on ImPACT performance. A repeated measures design was used to assess 104 healthy, college-aged students. Participants completed the Profile of Mood States-Brief (POMS-B) and the ImPACT at days 1, 45, and 50. Pearson correlation coefficients were calculated for the POMS-B and ImPACT composite scores. At day 1, the ImPACT's Impulse Control composite score was significantly correlated to POMS-B Fatigue-Inertia mood state (-0.23},
