Return to Sport Following Adolescent Concussion: Epidemiologic Findings From a High School Population

摘要

High school athletes sustaining a concussion require careful attention when determining return-to-sport (RTS) readiness. The purpose of this study was to determine epidemiological and RTS data of a large cohort of high school athletes who sustained 1 or more concussions. Records of 357 consecutive youth patients who sustained concussions and presented to a single health care system between September 2013 and December 2016 were reviewed. Demographic data, RTS, and concussion-related variables were obtained via chart review. Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) scores at baseline and following concussions were performed by neuropsychologists. The average age at injury was 15.5 years (range, 14-18 years), 61.9% of patients were male, 6.7% reported a loss of consciousness, and 14.3% reported amnesia, requiring 30.4 +/- 23.3 days of recovery prior to RTS. The most common sport of injury was football (27.7%). There was a high incidence of previous concussion (33.1%), and 32 athletes sustained a recurrent concussion. A multivariate model demonstrated that females, players with a history of concussion, and those diagnosed in-clinic rather than in-game required increased time to RTS. Memory ImPACT scores were found to increase as players had recurrent concussions. Visual motor speed and reaction time scores decreased with recurrent concussions.
