A CPM (continuous passive motion) machine is a device that is used to gently flex and extend the knee joint. A knee replacement patient can spend several hours a day in this machine. The foot rests in the end and the leg is placed along the length of the machine. When turned on the machine bends and straightens the knee again and again and again.
It doesn't look too painful with all the cushioned, soft padding. But let me tell you, being strapped in the machine for FOUR HOURS EVERY DAY is not so fun. What else isn't so fun? Physical therapy. One week with a new joint and a couple dozen staples running down the knee and I'm walking on a treadmill? Doing exercises on a balance board? Ouchy!
But it'll all be worth it when I can walk again. I continue to be hopeful for the future and grateful for the present.
