Which principle guides rehabilitation progression after injury?

• A. Time-based progression by days
• B. Criterion-based progression using objective milestones
• C. Progression based on coach's preference
• D. Progression based on patient desire

Answer: (B)

Progression after an injury should be guided by objective milestones that reflect actual recovery, not simply by a calendar or personal preferences. Criterion-based progression advances only when measurable criteria are met, such as reduced pain and swelling, restored range of motion, sufficient strength, and the ability to perform controlled, sport-specific tasks without symptoms. This approach adapts to each athlete’s healing timeline, ensuring the tissue is ready to handle progressively higher loads and demands, which helps prevent re-injury and supports functional return.

Relying on a fixed number of days can be misleading because healing rates vary between individuals and injuries, so a strict timetable may push too soon or stall progress longer than necessary. Decisions based on a coach’s preference or a patient’s desire ignore the underlying tissue status and safety considerations, potentially risking setbacks. By grounding progression in objective milestones, rehabilitation stays patient-specific, evidence-informed, and focused on restoring true function.
