ヒトの筋の粘弾性変化の推定

Abstract

In order to study the dynamics of the human arm experimentally, at first we developed an adjustable mechanical impedance device acts as a mecanical load for testing the dynamic characteristics of the manipulatory systems. The device consists of a pair of electromagnetic powder cultches and geared motors. It shows good linear characteristics in the visco-elastic motin and performs high speed low inertial motion. The second, we carried out some ramp target tracking experiments on the wrist joint of man using the device. Then we got results showing that visco-elastic coefficient of the human muscle is regulated by its activity,
