✓ Correct answer: C. Prevention of joint stiffnessAnswer: Prevention of joint stiffness Continuous passive motion (CPM) involves the use of a device to move a joint slowly and continuously through a controlled range of motion. This intervention is beneficial after a total knee arthroplasty by preventing joint stiffness and improving circulation. The remaining options are common effects of other physical therapy interventions. Soft tissue stretching, joint mobilization, and muscle relaxation can be achieved through manual therapy techniques but are not the primary goals of CPM.
