Continuous passive motion (CPM) is contraindicated in which scenario?

• A. Inc in pain after use
• B. Improved ROM
• C. Reduced edema
• D. Pain relief

Answer: (A)

The situation being tested is when CPM should not be used. Continuous passive motion is meant to help joints move gently to prevent stiffness and aid healing. It is typically beneficial when the device leads to improved range of motion, reduced swelling, and either pain relief or stable comfort.

However, if using CPM causes an increase in pain after the session, that indicates tissue stress or overloading, suggesting the joint or surrounding tissues aren’t ready for motion or there may be an issue with the setup. In that case, continuing CPM can hinder healing or worsen inflammation, so it is Contraindicated in this scenario.

The other responses describe favorable outcomes (better ROM, less edema, pain relief), which are not contraindications.
