Continuous Passive Motion (CPM) for Total Knee Replacement (TKR)
— Does prolongued use help?
Wednesday, May 7th, 2008
Researchers in the Netherlands set about to answer this question. . .
“What is the effect on range of motion and functional status of prolonged use of a continuous passive motion device at home in addition to PT, compared to PT alone, in patients with limited flexion range of motion (less than 80°) of the knee at discharge from the hospital after total knee arthroplasty?”
They used a blinded, randomized controlled trial. All participants received the following four day in-hospital protocol: CPM treatment of 2 consecutive hours, 2x/day (total 4 hours) plus 20 minutes of PT treatment.
