Description
Clinical Question: In adolescent athletes participating in contact sports, does rule modification or contact restriction reduce sport-related concussion incidence compared with standard full-contact rules? Background: Sport-related concussion remains a major concern in youth athletics. Structural prevention strategies, such as limiting contact exposure, have been proposed as effective approaches, though their comparative effectiveness remains under review. Methods: A critically appraised topic (CAT) was conducted using Google Scholar to identify peer-reviewed studies from the past 15 years examining rule modification or contact restriction as primary prevention strategies. Six high-quality studies met inclusion criteria, including one meta-analysis, one systematic review, prospective cohort studies, and a policy statement. Results: Evidence consistently showed that reducing athlete-to-athlete contact—such as delaying body checking in youth hockey and limiting full-contact practices—significantly decreased concussion incidence. Studies on head impact exposure supported these findings. Equipment-based and education-only interventions demonstrated inconsistent effects. Conclusions: Rule modification and contact restriction are the most consistently supported strategies for reducing sport-related concussion in adolescent contact sports. Policies that limit high-risk contact should be prioritized in prevention efforts
Research Highlights
The Problem: Adolescent sport-related concussions (SRC) are prevalent in contact sports like football, hockey, and soccer, driven by head impacts that cause rapid acceleration and deceleration forces.
The Method: A Critically Appraised Topic (CAT) analyzed six high-quality peer-reviewed studies from a 15-year period, including one meta-analysis, one systematic review, and prospective cohort studies involving athletes aged 18 and under.
Quantitative Finding: Data from youth ice hockey shows that injury rates per 1,000 player-hours are significantly higher in leagues with body checking compared to non-checking leagues.
Qualitative Finding: Rule modifications and contact restrictions, such as removing body checking and limiting contact during practices, are the most effective primary prevention strategies; equipment and education-based strategies like improved helmet technology or tackling techniques show limited or inconsistent effectiveness.
