We have developed a system measuring a range of motion of hand, using image analysis of the monitor image transfered by a tele-rehabilitation-system. Occupational therapists and physical therapists reported that this system was useful enough when it was applied for healthy individuals.
However, we also pointed out that it was still insufficient to evaluate the progress toward recovery of patients. The authors examined the detection axis model by the cluster analysis, to examine patients with rehabilitation in high precision. Our past methods of measuring a range of motion involved two axes, one on basic level and the other on movement level. The proposed method uses three axes. We added an axis based on the palm. We have compared these two measuring methods which are the two axes model and the three axes current one. We have compared them in measuring a range of motion with nine patients.
The result shows that the three axes method has enough capabilities to detect a range of motion of hand with sufficient precision.
