Racial Disparities in Concussion Knowledge and Symptom Recognition in American Adolescent Athletes.

White athletes had more concussion knowledge than African-American athletes; however, African-Americans that had access to an athletic trainer at their respective school were more likely to identify the signs and symptoms of concussion compared to African-Americans that did not have access to an athletic trainer. This further accentuates the health disparity that occurs in high school athletics, in regard to the presence of an athletic trainer and their influence on an athlete's health and safety.
