Which indicates readiness to progress a strengthening program in rehab?

• A. Increased swelling
• B. Pain-free ROM gains
• C. Muscle fatigue after exercise
• D. Pain on resisted movement

Answer: (B)

Tissue tolerance to loading is the key idea. When you’re ready to progress a strengthening program, you want to see movement through the full range without pain and without new symptoms. Pain-free ROM gains show the joint and surrounding tissues have recovered enough to handle the added load, and function has improved without irritation.

Increased swelling suggests ongoing inflammation or edema, which makes loading risky. Muscle fatigue after exercise can occur as you start a new program, but it isn’t by itself a reliable sign of readiness and can reflect insufficient recovery or overloading. Pain on resisted movement indicates the tissue is still irritable and not ready to tolerate strengthening loads.

So, pain-free ROM gains are the best indicator that you can safely progress to strengthening.
