CPM is an abbreviation for Continuous Passive Motion, which is used for rehabilitation exercises of the range of movement like shoulder joint inflammation. In my case, 5 times for both arms per a week.
At first it hurts much, but I have got used to it. The frozen my arms which moved gradually moved.
The appearance is masochistic torture. But this precise passive rehabilitation saves me than hand massage, also from analgesic addiction.
