In TSA and rTSA phase 4 rehab, loading is progressed cautiously based on what factor?

In TSA and rTSA phase 4 rehab, loading is progressed cautiously based on what factor?

• A. Pain
• B. Range of Motion
• C. Strength
• D. Time Since Surgery

Answer: (A)

Loading in the later stages of TSA and reverse TSA rehab is guided by the patient’s pain because pain serves as the best indicator of tissue tolerance. After joint replacement, healing of soft tissues and the surrounding structures continues for weeks to months, and different individuals recover at different rates. Using pain as the primary signal helps ensure you don’t overload healing tissues. If symptoms remain mild and manageable during a movement or loading task, you can safely progress the load. If pain increases or becomes refractory, that signals tissue irritability and loading should be reduced or paused. Range of motion, strength, and time since surgery are important context, but they don’t directly reflect how well tissues will tolerate new stress at a given moment. ROM might be limited by stiffness even when tissues can tolerate added loading, and strength gains don’t always track with tissue tolerance to loading. Time since surgery is an estimate of healing, not a precise measure of current tolerance, which is why pain is the primary guide for progression in phase 4.
