OBJECTIVE Concussion is a prevalent brain injury in sport and the wider community. Despite this, little research has been conducted investigating the dynamics of impacts to the unprotected human head and injury causation in vivo, in particular the roles of linear and angular head acceleration. SETTING Professional contact football in Australia. PARTICIPANTS Adult male professional Australia...

BACKGROUND Parents of young athletes play a major role in the identification and management of sports-related concussions. However, they are often unaware of the consequences of concussions and recommended management techniques. HYPOTHESIS This study quantitatively assessed parental understanding of concussions to identify specific populations in need of additional education. We predicted tha...

Abstract Objective The purpose of this study was to evaluate whether self-reports cognitive symptoms were associated with test performances. Methods sample included 112 Canadian Football League (CFL) athletes who diagnosed using CFL concussion protocols. All participants underwent a assessment at baseline and prior medical clearance. battery the immediate post-concussion testing (ImPACT) Post-C...

IMPORTANCE To our knowledge, this is the first study to show an association between concussion, cognition, and anatomical structural brain changes across the age spectrum in former National Football League athletes. OBJECTIVE To assess the relationship of hippocampal volume, memory performance, and the influence of concussion history in retired National Football League athletes with and witho...

OBJECTIVE A study to examine the incidence and characteristics of concussions among Canadian university athletes during 1 full year of football and soccer participation. DESIGN Retrospective survey. PARTICIPANTS Three hundred eighty Canadian university football and 240 Canadian university soccer players reporting to 1999 fall training camp. Of these, 328 football and 201 soccer players retu...

Sports concussions are an increasingly recognized common type of mild traumatic brain injury (TBI) that affect athletes of all ages. The need for an increased involvement of trained physicians in the diagnosis and treatment of concussion has become more obvious as the pathophysiology and long-term sequelae of sports concussion are better understood. To date, there has been great variability in ...

CONTEXT Concussed athletes may underreport concussion-related symptoms in order to expedite return to play. Whether neurocognitive impairments persist once concussion-related symptoms resolve has yet to be determined. Reliance on athlete-reported, postconcussion symptoms when making return-to-play decisions may expose athletes to subsequent injury if complete recovery has not occurred. OBJECT...

OBJECTIVE Previous studies suggest athletes underreport concussions. We sought to determine whether athletes in our clinics have sustained previous concussions that went undiagnosed. DESIGN Multicentered cross sectional study. SETTING Two sport concussion clinics. PATIENTS Patients diagnosed with sport-related concussions or concussions with injury mechanisms and forces similar to those o...

AIM To investigate incidence of concussion, clinical outcomes and subsequent injury risk following concussion. METHODS In a two-season (2012/2013, 2013/2014) prospective cohort study, incidence of diagnosed match concussions (injuries/1000 h), median time interval to subsequent injury of any type (survival time) and time spent at each stage of the graduated return to play pathway were determi...

BACKGROUND Athletic trainers (ATs) play an important role in the evaluation, management, and referral of student-athletes after sport-related concussion. Understanding factors that influence ATs' patient care decisions is important to ensure best practices are followed. PURPOSE To identify ATs' current concussion management practices and referral patterns for adolescent student-athletes after...
