Continuous Passive Motion Machine: What Went Wrong
The Continuous Passive Motion Machine is a device designed in the early 1970’s with the idea of helping knee surgery patients regain range of motion. The hope was that hours of moving the leg back and forth would loosen up the knee and allow the patient to gain extension (knee movement up, away from the body) and flexion (knee movement down, back toward the body).
Continuous Passive Motion Machine, Conclusive Results
For people who have had total knee replacement without complications, continuous passive motion has not been shown to provide clinically relevant benefits.
