Which condition is an indication for the use of CPM?

• A. Limited ROM
• B. Severe infection
• C. Unstable fracture
• D. Open wound

Answer: (A)

Continuous passive motion is used to preserve and gradually improve joint mobility after injury or surgery by delivering controlled, painless movement to the joint without active muscle effort. It helps prevent stiffness and adhesions, promotes circulation, and supports the healing of articular structures by continually stimulating synovial fluid distribution. When a patient has limited range of motion after immobilization or a procedure, CPM can be started to gradually increase movement and reduce the risk of arthrofibrosis. Conversely, conditions like active infection, an unstable fracture, or the presence of an open wound require immobilization and protection, because movement could worsen infection, destabilize the fracture, or impair wound healing. Therefore, limited range of motion is the situation that indicates the use of CPM.
