Comparing Persisting Post-Concussion Symptoms in Emergency Department Versus Clinical Rehabilitation Samples

This observational study compared characteristics of adults with persisting post-concussion symptoms (3-18 months post-injury) across two samples: 92 participants followed prospectively from an emergency department and 106 patients referred to outpatient rehabilitation. The clinical rehabilitation sample showed greater symptom severity, worse functional outcomes, and lower return-to-work rates, suggesting treatment-seeking patients represent a more severely affected subgroup.
