What is the hallmark of an appropriate return-to-activity protocol for concussion?

• A. Advancing if patient reports fatigue
• B. Advancement based solely on time since injury
• C. All athletes return on same schedule regardless of symptoms
• D. Symptom-free at each stage before advancing

Answer: (D)

The hallmark is moving to the next stage only after the individual is symptom-free at the current level. This symptom-guided, stepwise approach reflects that concussion recovery varies and hinges on whether exertion or cognitive load provokes symptoms. By requiring no symptoms before advancing, you reduce the risk of relapse, prolongation of recovery, or complications if another head impact occurs. Time alone, or advancing based on fatigue or a fixed schedule regardless of how the person feels, can miss ongoing problems and expose the athlete to unnecessary risk. Returning all athletes on the same timetable also ignores individual recovery and can push someone forward while still symptomatic. So, the best answer emphasizes progression only when the athlete is symptom-free at each stage.
