Multiple Concussions Increase Odds and Rate of Lower Extremity Injury in National Collegiate Athletic Association Athletes After Return to Play.
Source: AJSM first published September 12, 2016
Clinical Purpose: To better understand the relationship between concussion and lower extremity injury after return to play
Bottom Line: Collegiate athletes with multiple concussions were more likely to sustain a lower extremity injury after return to play in a shorter time frame than were the matched single and no concussion history athletes.
Points to Consider: 48 NCAA Div I athletes with multiple concussions were followed at one institution. Athletes with multiple concussions were matched directly to athletes with a single concussion and to athletes with no concussion history by sex, sport, position and games played. Incidence of, time to, and location of lower extremity injury were recorded for each group after return to play from first reported concussion.
Takeaway: The incidence of lower extremity injury after return to play was significantly greater (P = .049) in the multiple concussion cohort. Time to lower extremity injury was also significantly shorter in athletes with multiple concussions. There was no different in odds of lower extremity injury or time to lower extremity injury between single and no concussion history athletes.
