Effect of Neck Muscle Strength and Anticipatory Cervical Muscle Activation on the Kinematic Response of the Head to Impulsive Loads
Background: Greater neck strength and activating the neck muscles to brace for impact are both thought to reduce an athlete’s risk of concussion during a collision by attenuating the head’s kinematicExpand

Using stable isotopes and quantitative community characteristics to determine a local hydrothermal vent food web
To investigate food web structure in diffuse flow vent environments, an entire macro- faunal community associated with a single aggregation of the tubeworm Ridgeia piscesae was col- lected from aExpand

Cumulative head impact burden in high school football.
Impacts to the head are common in collision sports such as football. Emerging research has begun to elucidate concussion tolerance levels, but sub-concussive impacts that do not result in clinicalExpand

Pilot evaluation of a novel clinical test of reaction time in national collegiate athletic association division I football players.
CONTEXT Evidence suggests that concussion prolongs reaction time (RT). We have developed a simple, reliable clinical tool for measuring reaction time that may be of value in the assessment ofExpand

Post-concussion cognitive declines and symptomatology are not related to concussion biomechanics in high school football players.
Concussion is a major public health concern with nearly 4 million injuries occurring each year in the United States. In the acute post-injury stage, concussed individuals demonstrate cognitiveExpand

Cognitive Decline and Aging: The Role of Concussive and Subconcussive Impacts
Concussion has been viewed historically as a transient injury with no evidence supporting the existence of persistent effects. However, our recent work demonstrates electroencephalographic and motorExpand

A National Study on the Effects of Concussion in Collegiate Athletes and US Military Service Academy Members: The NCAA–DoD Concussion Assessment, Research and Education (CARE) Consortium Structure
BackgroundThe natural history of mild traumatic brain injury (TBI) or concussion remains poorly defined and no objective biomarker of physiological recovery exists for clinical use. The NationalExpand

Effect of sport-related concussion on clinically measured simple reaction time
Background Reaction time (RT) is a valuable component of the sport concussion assessment battery. RT is typically measured using computers running specialised software, which limits its applicabilityExpand

Between-seasons test-retest reliability of clinically measured reaction time in National Collegiate Athletic Association Division I athletes.
CONTEXT Reaction time is typically impaired after concussion. A clinical test of reaction time (RT(clin)) that does not require a computer to administer may be a valuable tool to assist in concussionExpand
