OBJECTIVE To examine the incidence and characteristics of concussions for one season in the Canadian Football League (CFL). DESIGN Retrospective survey. PARTICIPANTS 289 players reporting to CFL training camp. Of these, 154 players had played in the CFL during the 1997 season. MAIN OUTCOME MEASURES Based on self-reported symptoms, calculations were made to determine the number of concussi...

BACKGROUND AND PURPOSE Although concussion is common among athletes, evidence-based methods for clinical evaluation, treatment, and recovery are lacking. We used a prospective, functional neuroimaging approach to assess sports-related concussion in which imaging was performed before injury so that brain changes resulting from concussion could be better understood. METHODS Neurophysiologic cor...

UNLABELLED Abstract Objective: To assess the characteristics of current clinical trials investigating the treatment of concussion. BACKGROUND Recent systematic literature reviews have concluded that there is minimal evidence to support any specific treatment for concussion, including the principles of return-to-activity protocols such as type or duration of rest. DESIGN/METHODS Clinical tri...

PRIMARY OBJECTIVE The purpose of the present study was to examine deficits in the alerting, orienting and executive components of attention in individuals who have recently suffered a concussion. RESEARCH DESIGN A group design was used in which the performance by individuals with concussion was compared to control subjects matched for age, height, weight and activity level. METHODS AND PROC...

BACKGROUND Few protocols exist for returning children/youth to school after concussion. Childhood concussion can significantly affect school performance, which is vital to social development, academic learning, and preparation for future roles. The goal of this knowledge translation research was to develop evidence based materials to inform physicians about pediatric concussion. METHODS The R...

Abstract Background The Sports Concussion Assessment Tool (SCAT) is recommended to screen for concussion following head impact events in elite sport. most recent 5th edition (SCAT5) included a ‘rapid neurological screen’ which introduced new subtests examining comprehension, passive neck movement, and diplopia. This study evaluated the additional diagnostic value of these subtests. Methods A pr...

CONTEXT Self-reported symptoms (SRS) scales comprise one aspect of a multifaceted assessment of sport-related concussion. Obtaining SRS assessments before a concussion occurs assists in determining when the injury is resolved. However, athletes may present with concussion-related symptoms at baseline. Thus, it is important to evaluate such reports to determine if the variables that are common t...

OBJECTIVES To investigate the association of concussion with cognitive ability (CA) and educational level (EL). DESIGN Epidemiological-cross-linkage of national computer registers. SETTING Denmark. PARTICIPANTS 130 420 young men appearing before the Danish draft board during the period 2006-2010. PRIMARY AND SECONDARY OUTCOME MEASURES CA test scores, EL and occurrence of concussion duri...

OBJECTIVE The aim of the current review was to systematically identify, evaluate and synthesise trials that examine concussion prevention via equipment, educational programmes and training programmes. DATA SOURCES PubMed and EBSCO host (CINAHL, MEDLINE, SPORTDiscus). ELIGIBILITY CRITERIA FOR SELECTING STUDIES The electronic databases PubMed and EBSCO were searched using the phrases: concuss...

BACKGROUND Concussion, particularly in relation to sports and combat activities, is increasingly recognized as a potential cause of both short- and long-term neurologic sequelae. This review will focus on the neuro-ophthalmologic findings associated with concussion, the current tests for concussion, and the potential for visual performance measures to improve our detection and assessment of con...
