Today, multiple sports are associated with concussive events. In excess of 1.5 million people participate in football (i.e. recreational, high school, collegiate, and professional) annually. The estimated annual incidence of MTBI’s in football is 4–20%.5 A systematic review of the literature from 1985 to 2000 found ice hockey and rugby to have the highest incidence of concussion for high school, college, and amateur athletes, while soccer had the lowest.10 At the recreational level, female taekwondo participants and male boxers had the highest frequency of concussion.10 Of the injuries, 6.2% were concussive in a three-year prospective study among intercollegiate athletes.11 According to a survey of 1,659 children participating in contact sports, 3% suffered concussions.12 In addition, an epidemiologic study of collegiate and high school football players found that players who sustain one concussion are three times more likely to sustain a second one in the same season.13
