OBJECTIVES Concussion remains one of the inherent risks of participation in rugby league. While other injuries incurred by rugby league players have been well studied, less focus and attention has been directed towards concussion. REVIEW METHOD The current review examined all articles published in English from 1900 up to June 2013 pertaining to concussion in rugby league players. DATA SOURC...

Concussion is a physiologic brain injury that produces systemic and cognitive symptoms. The metabolic and physiologic changes of concussion result in altered autonomic function and control of cerebral blood flow. Evaluation and treatment approaches based upon the physiology of concussion may therefore add a new dimension to concussion care. In this article, we discuss the use of a standard trea...

The myth of concussion definition There is no universal agreement on the standard definition of concussion. The most widely accepted definition in sports medicine is that originally proposed by the Congress of Neurological Surgeons. It states that “concussion is a clinical syndrome characterised by the immediate and transient post-traumatic impairment of neural function...”. The key elements of...

OBJECTIVE This study examined components of the Sports Concussion Assessment Tool, 3rd Edition (SCAT3) and a vision-based test of rapid number naming (King-Devick [K-D]) to evaluate sports and non-sports concussion patients in an outpatient, multidisciplinary concussion center. While the Symptom Evaluation, Standardized Assessment of Concussion (SAC), modified Balance Error Scoring System (BESS...

protocols. T he word “concussion” derives from the Latin concussus, which means to shake violently. Concussion was initially felt to involve only transient disturbance of brain function without gross structural change. It is now recognized that some concussions do involve structural damage with loss of neurons. Sports concussion is defined as a complex pathophysiological process af fecting the ...

Concussion is a physiological injury to the extremely complex and dynamic human brain. Individual variability adds to the challenge of concussion management, and sports medicine practitioners recently have begun to realize the need for an individualized approach. Adequately assessing an athlete with concussion requires consideration of many risk factors, including age, gender, and certain comor...

Concussion is a clinical syndrome of biomechanically induced altered brain function that typically affects memory and orientation, and may involve loss of consciousness. An estimated 1.6 to 3.8 million sports-related concussions occur each year in the United States. The American Academy of Neurology (AAN) studied the incidence of concussion in high school and college athletes to address the fol...

AIM The need for accurate diagnosis and appropriate return-to-play decisions following a concussion in sports has prompted the dissemination of guidelines to assist managing this condition. This study aimed to assess whether key messages within these guidelines are reflected in the knowledge of coaches and sports trainers involved in community sport. METHODS An online knowledge survey was wid...

OBJECTIVE A common assumption in sports medicine is that a history of concussion is predictive of a lower threshold for, as well as a worse outcome after, subsequent concussive injury. The current study was conducted to investigate the relationship between concussion history in high school athletes and the on-field presentation of symptoms after subsequent concussion. METHODS One hundred seve...

CONTEXT Prolonged symptoms after concussion are called post-concussion syndrome (PCS), which is a controversial disorder with a wide differential diagnosis. EVIDENCE ACQUISITION MEDLINE and PubMed searches were conducted for the years 1966 to 2011 using the search terms brain concussion/complications OR brain concussion/diagnosis OR brain concussion/therapy AND sports OR athletic injuries. Se...
