Key Finding

Synthesizing evidence from 7 qualifying studies, sub-symptom threshold aerobic exercise consistently improved symptom severity and exercise tolerance in adolescents with persistent post-concussion symptoms (≥28 days post-injury). The evidence supports an individualized, heart-rate-guided exercise prescription over strict rest protocols.

What’s Next

This work forms the clinical foundation for a larger Bayesian systematic review and meta-analysis currently in progress. The meta-analysis will quantify pooled effect sizes across exercise intervention studies using hierarchical Bayesian models (brms/Stan), providing stronger inferential support for clinical guidelines.
