Activity Level During Acute Concussion May Predict Symptom Recovery Within an Active Duty Military Population

Objective: To evaluate the impact on symptom resolution of activity acutely following a concussion and the role of acute-phase symptoms on this relationship among active duty service members (SMs). Setting: Three military installations. Participants: Sixty-two SMs aged 18 to 44 years who sustained a concussion within 72 hours of enrollment. Design: Longitudinal design with data collected within 72 hours of injury (baseline, n = 62) and at 1 week (n = 57), 1 month (n = 50), 3 months (n = 41), and 6 months (n = 40) postinjury. Main Measures: Baseline activity level using a 60-item Activity Questionnaire. Symptom level at baseline and during follow-up using Neurobehavioral Symptoms Inventory. Results: Significant interaction (Pi
