Continuous Passive Motion is a modality that applies an external force to move the joint through a preset arc of motion. It primarily is used postsurgically at the knee, after knee manipulation, or after stable fixation of intra-articular and extra-articular fractures of most joints, such as the hand, wrist, hip, shoulder, elbow, and ankle. What is CPM primarily used for?

It primarily is used postsurgically at the knee, after knee manipulation, or after stable fixation of intra-articular and extra-articular fractures of most joints, such as the hand, wrist, hip, shoulder, elbow, and ankle. What is CPM primarily used for?

• A. Active strengthening
• B. Postoperative joint motion within a preset arc
• C. Thermal therapy
• D. Electrical stimulation to nerves

Answer: (B)

Continuous Passive Motion provides controlled, passive movement of a joint through a predefined arc after surgery. Its primary use is to achieve postoperative joint motion within a preset arc, protecting repairs while preserving mobility. This approach helps prevent stiffness and contractures, supports tissue healing by guiding motion without requiring active muscle contraction, and promotes lubrication and nutrient exchange in the joint. It’s not for active strengthening, nor a thermal therapy method, nor electrical stimulation, and is commonly used after knee surgeries or fixation of fractures across various joints to facilitate early, safe range of motion.
