OBJECTIVEIt has been speculated that a theoretical injury threshold of 70 to 75 g may exist for concussions in football players. We aimed to investigate acute balance and neurocognitive performance after head impacts exceeding a theoretical injury threshold in the absence of both self-reported symptoms and a concussion diagnosis 24 hours before testing. METHODSForty-three Division I collegiate football players participated in this double-blind, repeated-measures study. Subjects participated in…

Measurement of Head Impacts in Collegiate Football Players: Relationship Between Head Impact Biomechanics and Acute Clinical Outcome After Concussion
TLDR
It is suggested that football players are concussed by impacts to the head that occur at a wide range of magnitudes and that clinical measures of acute symptom severity, postural stability, and neuropsychological function all appear to be largely independent of impact magnitude and location.
MEASUREMENT OF HEAD IMPACTS IN COLLEGIATE FOOTBALL PLAYERS: RELATIONSHIP BETWEEN HEAD IMPACT BIOMECHANICS AND ACUTE CLINICAL OUTCOME AFTER CONCUSSION
TLDR
It is suggested that football players are concussed by impacts to the head that occur at a wide range of magnitudes and that clinical measures of acute symptom severity, postural stability, and neuropsychological function all appear to be largely independent of impact magnitude and location.
The Relationship Between Subconcussive Impacts and Concussion History on Clinical Measures of Neurologic Function in Collegiate Football Players
TLDR
Repetitive subconcussive head impacts over a single season do not appear to result in short-term neurologic impairment, but these relationships should be further investigated for a potential dose–response over a player’s career.
Validation of Concussion Risk Curves for Collegiate Football Players Derived from HITS Data
TLDR
Analysis of data from 37,128 head impacts collected at Virginia Tech during games from 2006 to 2010 demonstrates that simple biomechanical parameters that can be measured by the HIT System possess a high level of power for predicting concussion.
Potential Mechanisms of Acute Standing Balance Deficits After Concussions and Subconcussive Head Impacts: A Review.
TLDR
Evidence linking head impact biomechanics to standing balance deficits and a link between tissue deformations in deep brain regions including the brainstem and common post-concussion balance-related deficits is consolidated.
No evidence for a cumulative impact effect on concussion injury threshold.
TLDR
The data do not support the proposal that impact volume or intensity influence concussion threshold in high school football athletes, and no differences were present in any impact history variable between the concussive and non-concussive high magnitude impacts.
MEASUREMENT OF HEAD IMPACTS IN COLLEGIATE FOOTBALL PLAYERS: AN INVESTIGATION OF POSITIONAL AND EVENT‐TYPE DIFFERENCES
TLDR
Impacts sustained during helmets-only practices were greater than those sustained in games or scrimmages; there seem to be no “light” days for football players; more injury data are required before any theoretical thresholds for injury can be confirmed.
A Study of Visual and Sensory Performance, Collision Anticipation, and Head Impact Biomechanics in College Football Players
The purpose of this study was to determine the relationship between traditional and visual sensory measures of reaction time; and the associations between visual and sensory performance, collision
Measurement of head impacts in youth ice hockey players.
TLDR
This pilot study describes the biomechanical measures of head impacts in youth minor ice hockey players and investigates the influence of player and game characteristics on the number and magnitude ofHead Injury Criterion.
The Effect of Play Type and Collision Closing Distance on Head Impact Biomechanics
TLDR
Collisions occurring on special teams plays over long closing distances were most severe while collisions occurring onspecial teams and defensive plays over short closing distances resulted in the least severe impacts.

Alternative approaches to the assessment of mild head injury in athletes.
TLDR
The results from this study indicate that athletes demonstrate decreased stability until 3 days postinjury, and it appears this deficit is related to a sensory interaction problem, whereby the injured athlete fails to use their visual system effectively.
Relationship between concussion and neuropsychological performance in college football players.
TLDR
It is suggested that neuropsychological assessment is a useful indicator of cognitive functioning in athletes and that both history of multiple concussions and learning disability are associated with reduced cognitive performance.
Postural Stability and Neuropsychological Deficits After Concussion in Collegiate Athletes.
TLDR
Athletes with cerebral concussion demonstrated acute balance deficits, which are likely the result of not using information from the vestibular and visual systems effectively, and more research is necessary to determine the best neuropsychological test battery for assessing sport-related concussion.

TLDR
It appears that postural stability testing provides a useful tool for objectively assessing the motor domain of neurologic functioning, and should be considered a reliable and valid adjunct to the assessment of athletes suffering from concussion.
Does age play a role in recovery from sports-related concussion? A comparison of high school and collegiate athletes.
TLDR
Preliminary data may suggest a more protracted recovery from concussion in high school athletes, and self-report of postconcussion symptoms by student athletes was not predictive of poor performance on neuropsychologic testing.

Neuropsychological Test Performance Prior To and Following Sports-Related Mild Traumatic Brain Injury
TLDR
Neuropsychological tests are useful in the detection of cognitive impairment following mTBI and appear to be more effective than subjective report of symptoms in differentiating between injured and noninjured athletes at 48 hours postinjury.
Balance Findings in a Child before and after a Mild Head Injury
TLDR
The good recovery of balance skills observed over the first month after injury seems to validate the current activity restrictions imposed on children after a mild head injury, however, the persistence of poor performance in the area of reactions to external perturbations indicates that some deficits may persist beyond what is expected with this population.
