Application of Motion Analysis of Upper Limbs to Evaluation of Self-motion in Music Therapy

Abstract

Recently music therapy is used to improve physical and mental condition of people. Since its evaluation is subjective at this moment, establishnment of objective methnod is needed. In this paper, we describe application of motion analysis of upper limbs to music therapy for handicapped children, and discuss on the desirable evaluation for self-motion during music therapy. To reduce influence on subject, two dimensional analysis using single camera was applied, and color tape-shaped marker was attached to the wrist and shoulder of the subject. We peformed analysis in 7 cases of 3 subjects and calculated the amplitude and frequency of motion of the arm. Results well reflectd subjective comment of the therapists, and showed that motion analysis is effective for evaluation of self-motion in music therapy.
