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 kinematic… Expand

Effects of surface irregularity and lighting on step variability during gait: a study in healthy young and older women.
Relatively few studies have examined how uneven surfaces affect human gait. To study this, along with the effects of advancing age and low light conditions, we measured step width and step time… Expand

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 of… Expand

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 applicability… Expand

Gender, body mass and age as risk factors for ulnar mononeuropathy at the elbow
Factors that predispose patients to ulnar mononeuropathy at the elbow (UME) are poorly defined. We compared 112 electrodiagnostic reports which met criteria for definite or probable UME to 104… Expand
