BACKGROUND Sports-related concussion remains a public health challenge due to its morbidity and mortality. One of the consequences of concussion is cognitive impairment (CI) and cognitive-related symptoms (CRS) which determine, to some extent, physical and behavioral functioning of children who sustain concussion. Despite the high prevalence of CI and CRS associated with concussion, the risk fa...

OBJECTIVE To assess heart rate variability (HRV) in athletes with concussion across three phases of recovery. DESIGN A prospective matched control group design included the collection of HRV and symptoms measured by the Rivermead Post-Concussion Questionnaire. These measures were taken at 3 phases of recovery [(1) symptomatic; (2). asymptomatic; and (3) one-week after return-to-play (RTP)]. T...

Introduction: Combat sport athletes are exposed to intentional strikes the head. These result in height linear and rotational acceleration forces that can concussion neck injury. Despite experiencing ongoing post-concussion symptoms, combat continue participate their sport. Neck muscle strength has been described as a modifiable risk factor for prevention of concussion, but found be reduced pre...

OBJECTIVE This study is the first to investigate the influence of a symptom-free waiting period (SFWP) on clinical outcome and risk of repeat injury after sport-related concussion. METHODS This was a prospective, nonrandomized study of 16 624 player seasons from 1999 to 2004, including a cohort of 635 concussed high school and college athletes grouped on the basis of an SFWP or no SFWP observ...

Although this approach will result in successful return to school and sports activities in the majority of athletes, an important proportion will develop persist...
