Screening Test Method for Motor Functional Decline of Shoulder Joint Function Based on Force Measurement

Abstract

　The final aim of this research is to develop a quantitative evaluation system of shoulder joint function using the three-dimensional force display robot. In this paper, we proposed a screening test method for motor functional decline of shoulder joint function. Firstly, we proposed an estimation method of joint angles of upper extremity during the constant velocity section by measuring the force exerted by a subject. Secondly we proposed a screeing test method by analying the motion of therapist's manual test. Lastly, by comparing the test results of the proposed method and the test results by the therapist, we confimed the screening accuracy of the porposed method.
