Immediate clinical steps to lower recurrence
Best evidence emphasizes early, expert-led management. Immediate removal from play and clinical evaluation by a trained provider reduce risk of a subsequent injury by preventing return to high-risk exposure while symptoms are unresolved. Paul McCrory of the Florey Institute of Neuroscience and Mental Health and colleagues in the Concussion in Sport Group endorse using standardized tools such as the Sport Concussion Assessment Tool and symptom-guided monitoring to inform care. Rapid recognition matters because returning while symptoms persist increases susceptibility to repeat concussion and prolonged recovery.
Graduated, individualized return-to-play
A staged, graduated return-to-play protocol supervised by clinicians is central to reducing recurrence. Steven P. Broglio at the University of Michigan and other rehabilitation researchers support progression from rest to controlled aerobic activity, then sport-specific training, with objective clearance before full contact. Protocols that integrate cognitive assessment, symptom tracking, and physical tolerance aim to ensure that underlying physiological vulnerability has resolved rather than relying solely on time-based rules.
Targeted rehabilitation and conditioning
Rehab that addresses vestibular, ocular, and cervical dysfunction after concussion reduces persistent symptoms that can predispose to later injury. Clinicians increasingly use vestibular-ocular therapy and neck-strengthening exercises as part of return-to-sport care. Evidence synthesized by concussion experts indicates that treating these impairments can shorten symptomatic periods and lower the chance of risky re-exposure when athletes resume play.
Policy, education, and cultural change
Population-level measures also cut recurrence. Caroline Emery at the University of Calgary demonstrated that rule changes and stricter enforcement in youth hockey—such as delayed introduction of body checking—reduce concussion incidence, thereby lowering the pool at risk for repeat injuries. Steven G. Guskiewicz at the University of North Carolina has shown that a prior concussion is a strong predictor of future concussion, highlighting the importance of prevention. Education that shifts hockey culture away from playing through injury, consistent sideline removal policies, and coach and parent training are necessary complements to clinical care.
Relevance and consequences extend beyond sport: recurrent concussions carry risks for prolonged disability, academic and occupational disruption, and mental health impacts. Combining prompt clinical management, individualized rehabilitation, conditioning that addresses modifiable risk factors, and policy-level prevention provides the strongest, evidence-aligned strategy to reduce concussion recurrence among hockey players.
