Progressive return-to-play after concussion: which option describes the correct criterion for advancement?

• A. Advanced only on coach's call
• B. No symptoms with progressive cognitive and physical tasks
• C. Progression based on time elapsed
• D. Progression regardless of symptoms

Answer: (B)

In return-to-play after a concussion, the guiding rule is that progression through each stage happens only if the athlete remains symptom-free as they gradually increase difficulty and intensity. This means you don’t move forward after a fixed time or because someone says to; you move forward only when there are no new or worsening symptoms while you perform progressively challenging cognitive and physical tasks.

Why this is the best approach: symptoms are the clearest signal of whether the brain is tolerating activity. If headaches, dizziness, sensitivity to light or noise, fatigue, or concentration problems appear or worsen, that indicates the brain hasn’t fully healed yet. Waiting until there are no symptoms at a given level ensures you’re exposing the brain to load in a controlled, safe way and helps prevent setbacks or a second injury. The gradual, symptom-guided progression also provides objective feedback for both the clinician and the athlete.

Context that helps understanding: the plan typically starts with very light activity and advances through a series of defined steps (short aerobic work, cognitive loading, sport-specific drills, then full practice) only as symptoms stay absent. If symptoms occur at any step, you pause and return to the previous asymptomatic level until recovery, then resume more slowly.

Other ideas, like advancing based on time alone or on a coach’s call or moving forward regardless of symptoms, don’t align with safety data. Time elapsed doesn’t reflect healing, a coach’s call can be inconsistent with the individual’s brain state, and progressing despite symptoms greatly increases the risk of prolonged recovery or another injury.
