What is the primary purpose of a CPM device?

The primary purpose of a Continuous Passive Motion (CPM) device is indeed to enhance mobility and promote healing. This type of device is designed to move a joint through a controlled range of motion without the patient needing to exert effort. The gentle and continuous movement helps maintain joint flexibility, reduce stiffness, and support the healing process after surgeries, particularly orthopedic procedures. By keeping the joint moving, CPM devices can minimize the risk of complications associated with immobility, such as joint contractures or deep vein thrombosis.

Mobility enhancement is crucial following surgeries or injuries, as it allows for better blood flow and nutrient delivery to the affected tissues, which is vital for effective recovery. The therapeutic benefits of a CPM device play a significant role in rehabilitation, making it an essential tool in post-operative care and treatment plans.

The other options, while related to rehabilitation, do not accurately describe the main function of the CPM device. For example, strength training for remaining limbs is typically addressed through different exercise regimens rather than passive motion devices. Similarly, medication delivery and weight support are functions that would require different types of devices or interventions not directly associated with the purpose of a CPM.
