Abstract
Rheumatoid arthritis (RA) patients in Japan are about eight hundred thousand. 80-90% of RA patients develop to the hands and wrist. When developing these, causing the dislocation and deformation of the finger. As treatment for subluxation due to RA, there is a rehabilitation by hand therapy, but therapist is not enough. Therefore a device for rehabilitation of thumb MP joint subluxation has been developed. To improve the device, it is necessary to clear the dynamics of hand therapy. Therefore, the authors tried to measurement four kind of rehabilitation by using motion capture and contact force sensor, and we will try develop the simulation function model for curative effect evaluations of hand therapy for RA. To develop simulation model, we think method of modeling of joint in rehabilitation and estimating the model parameters using measured data.
