How should we follow athletes after a concussion?

Abstract

Athletes sustaining a concussion should be held from contact activities a minimum of 7 days; they must be asymptomatic and their coordination and neuropsychological tests should have returned to their pre-injury baseline (strength of recommendation [SOR]: B, based on multiple prospective cohort studies). High-risk athletes (eg, those with a history of previous concussion, high- school age or younger, or female) may need to avoid contact even after all these criteria are met (SOR: C, expert opinion).
