Impact of legislation—Do athletes play with symptoms?

• Prospective cohort study1 • Rivara 2013, N=778 high school football and soccer players, N=83 concussions• 69% reported playing with concussive symptoms

• Prospective cohort study, before and after (natural history)2

• O’Kane 2014, N=351 female middle school soccer players (N=11 concussions before law, N=48 after)• No change in rate of concussions before vs. after• No sig change in proportion play with symptoms (70% vs. 56%)• 2x more likely to be diagnosed concussion if seen by provider

• Cross sectional survey, before and after (natural history)3

• La Roche 2015, N=1532 vs. N=206 (before and after law) high school football players• No change in proportion sustaining concussion season before (15% vs. 17%)• 47% reported before vs. 71% after. (p=0.011)
