What do continuous passive motion (CPM) machines assist with?

Continuous passive motion (CPM) machines are specifically designed to assist with joint rehabilitation and mobility. These devices are commonly used after surgical procedures, particularly orthopedic surgeries like knee or hip replacements, to promote healing and restore range of motion. By gently moving the joint through its range of motion without the patient having to exert effort, CPM machines facilitate circulation, reduce stiffness, and help maintain the health of surrounding tissues.

The primary goal of a CPM machine is to enhance recovery by keeping the joint functional and preventing complications such as adhesions or contractures. This is accomplished by providing a controlled, continuous movement that encourages synovial fluid production, which is essential for joint lubrication and nourishment.

The other options, while related to healthcare, serve different functions. Monitoring heart rates is typically handled by cardiac monitoring devices, respiratory function is managed with ventilators or spirometers, and drug delivery involves infusion pumps or other mechanisms for administering medications. Each of these plays a significant role in patient care, but they do not relate to the specific function of CPM machines in joint rehabilitation.
