What is a key purpose of progression criteria in rehabilitation?

• A. They are optional and not essential.
• B. They serve to document the injury history.
• C. They act as general guidelines without testing.
• D. They determine when it is safe to progress loading and tasks.

Answer: (D)

Progression criteria are objective checkpoints that tell you when it’s safe to increase loading or advance activities in rehab. They ensure the healing tissue can tolerate higher demands and that the athlete’s functional capacity meets the requirements of the next stage. By using specific targets—such as pain-free range of movement, adequate strength symmetry, absence of swelling, and successful performance on functional tests—the rehab plan progresses only when the body is ready, reducing the risk of re-injury. These criteria are essential and evidence-based, not merely records of injury history or vague guidelines. They guide safe, staged progression rather than guessing when to push harder.
