Abstract
Because medical caregivers are short, Continuous Passive Motion (CPM) devices are used for rehabilitation of the fingers of a patient. However, it is difficult to effectively flex the finger joints due to a gap between the device and the finger. So, we measured and discussed the gap for realizing the more effective rehabilitation of the fingers. We made a CPM device which had a link mechanism on the lateral surface of the right index finger, and analyzed three-dimensional motion of the index finger and the link mechanism during the flexion of the finger. Three methods to mount the finger with the device were tested; by some bands, by a net, and by a finger cot. We compared the maximum flexion angle and the range of motion of the finger joints among three methods.
