BACKGROUND: The epidemiology of sports-related concussion is not well-described in the literature. This paper presents a descriptive epidemiology of concussion in seven high school and collegiate sports. METHODS: We used the data from Concussion Prevention Initiative (CPI), which enrolled 8905 athletes at 210 high schools and 26 colleges in a prospective cohort study of 7 sports (football, men's and women's soccer, men's and women's lacrosse, and men's and women's ice hockey) between 1999 and 2001...

BACKGROUND: KINARM end point robotic testing on a range of tasks evaluating sensory, motor and cognitive function in children/adolescents with no neurologic impairment has been shown to be reliable. The objective of this study was to determine whether differences in baseline performance on multiple robotic tasks could be identified between pediatric/adolescent ice hockey players (age range 10-14) with and without a history of concussion. METHODS: Three hundred and eighty-five pediatric/adolescent ice hockey players (ages 10-14) completed robotic testing (94 with and 292 without a history of concussion)...

OBJECTIVES: To examine test-retest reliability of the SCAT3 for two consecutive seasons using a large sample of professional male ice hockey players, and to make recommendations for interpreting change on the test. DESIGN: A cross-sectional descriptive study. METHODS: Preseason baseline testing was administered in the beginning of the seasons 2013-2014 and 2014-2015 to 179 professional male hockey players in rink side settings. RESULTS: The test-retest reliabilities of the SCAT3 components were uniformly low...

OBJECTIVE: The purpose of this study is to describe the chiropractic management of a student athlete with postconcussion syndrome. CLINICAL FEATURES: A 14-year-old male hockey player presented to a chiropractic clinic with postconcussion symptoms 13 days after his initial injury. He experienced an occipital headache with a pain rating of 8/10, upset stomach, blurry vision, nausea, dizziness, balance problems, a "foggy feeling," difficulty with concentration, difficulty with memory, fatigue, confusion, drowsiness, and irritability...

BACKGROUND/AIMS: Concussion is widely discussed in online sports news articles, but the terms used to report this injury vary. This study aimed to use a systematic search strategy and explore the description of sports concussion in online sports news articles. METHODS: A systematic approach was employed to obtain online articles related to sports concussion from four sports associated with concussion (hockey, football, soccer, and rugby). Included articles were evaluated for the descriptors used in relation to concussion and possible consequences associated with concussion...

BACKGROUND: The diagnosis of a sports-related concussion is often dependent on the athlete self-reporting their symptoms. It has been suggested that improving youth athlete knowledge and attitudes toward concussion may increase self-reporting behaviour. The objective of this study was to determine if a novel Concussion-U educational program improves knowledge of and attitudes about concussion among a cohort of elite male Bantam and Midget AAA hockey players. METHODS: Fifty-seven male Bantam and Midget AAA-level hockey players (mean age=14...

INTRODUCTION: Concussion diagnosis and management is a topic of interest for health care, education, and government professionals. Given the evidence concerning the association of long-term effects and cumulative insult of multiple concussions, we sought to identify risk factors in young athletes for repeat injury. METHODS: This study is a retrospective cohort analysis of our institution's series of pediatric sports related concussions. Patient demographics, characteristics, and clinical features of concussion were analyzed in an unadjusted fashion...

In ice hockey, concussions can occur as a result of many different types of impact events, however hockey helmets are certified using a single injury scenario, involving drop tests to a rigid surface. The purpose of this study is to measure the protective capacity of ice hockey helmets for different impact events in ice hockey. A helmeted and unhelmeted Hybrid III headform were impacted simulating falls, elbow, shoulder and puck impacts in ice hockey. Linear and rotational acceleration and maximum principal strain (MPS) were measured...

Bill Masterton is the only man to die of injuries sustained in a National Hockey League (NHL) game. He remains the last fatality in any professional team sport involving a direct in-game injury in North America. While Masterton was originally thought to have suffered a fatal brain injury while being checked on the ice, later analysis of the case revealed evidence of second-impact syndrome and the effects of prior concussions. Masterton's death sparked both an immediate debate in the NHL on whether helmets should be compulsory and the NHL's first vote on mandatory helmet use...

CONTEXT:   Injury rates compare the relative frequency of sport-related concussions across groups. However, they may not be intuitive to policy makers, parents, or coaches in understanding the likelihood of concussion. OBJECTIVE:   To describe 4 measures of incidence (athlete-based rate, athlete-based risk, team-based rate, and team-based risk) during the 2011-2012 through 2014-2015 academic years. DESIGN:   Descriptive epidemiology study...

BACKGROUND: Detailed injury data are not available for international ice hockey tournaments played by junior athletes. We report the incidence, type, mechanism and severity of injuries in males under ages 18 and 20 at junior ice hockey World Championships during 2006-2015. METHODS: All injuries in the International Ice Hockey Federation World Junior under-20 (WJ U20) Championship and under-18 (WJ U18) Championship were collected over a 9-year period using a strict injury definition, a standardised injury reporting system and diagnoses made by a team physician...

BACKGROUND: In North America, more than 800,000 youth are registered in organized ice hockey leagues. Despite the many benefits of involvement, young players are at significant risk for injury. Body-checking and aggressive play are associated with high frequency of game-related injury including concussion. We conducted a qualitative study to understand why youth ice hockey players engage in aggressive, injury-prone behaviours on the ice. METHODS: Semi-structured interviews were conducted with 61 minor ice hockey participants, including male and female players, parents, coaches, trainers, managers and a game official...

The objective of this study was to describe the effect of concussion on upper and lower body strength in children and youth athletes. The participant group was made up of 178 unique male and female ice hockey players (ages 8-14 years). Using a 3-year prospective longitudinal research design, baseline and post-concussion data on hand grip strength, jump tests, and leg maximal voluntary contraction were collected. Using a linear mixed-effects model, no significant differences were found when comparing the baseline strength performance of individuals who went on to experience a concussion and those who did not...

INTRODUCTION: There are limited nonlaboratory soccer head impact biomechanics data. This is surprising given soccer's global popularity. Epidemiological data suggest that female college soccer players are at a greater concussion injury risk than their male counterparts. Therefore, the purposes of our study were to quantify head impact frequency and magnitude during women's soccer practices and games in the National Collegiate Athletic Association and to characterize these data across event type, playing position, year on the team, and segment of game (first and second halves)...

BACKGROUND: Few studies have empirically examined outcomes of concussion in the National Hockey League (NHL) and whether these athletes return to games after concussion at a performance level comparable to preconcussion play. HYPOTHESIS: NHL players would not demonstrate changes in performance or style of play after returning from a concussion when compared with a group of control athletes. STUDY DESIGN: Cohort study; Level of evidence, 3...

Repeated concussive and subconcussive trauma is associated with the later development of chronic traumatic encephalopathy (CTE), a neurodegenerative disease associated with clinical symptoms in multiple domains and a unique pattern of pathologic changes. CTE has been linked to boxing and American football; CTE has also been identified in soccer, ice hockey, baseball, rugby, and military service. To date, most large studies of CTE have come from enriched cohorts associated with brain bank donations for traumatic brain injury, although several recent studies re-examining neurodegenerative disease brain banks suggest that CTE is more common than is currently appreciated...
