Study on parameters identification of dynamic equation of human lower limb for improved estimation of muscular tensions

We have proposed a new rehabilitation support equipment that estimates the muscular tensions of lower limbs in order to offer it to the PTs and the patients in a comprehensible form to realize a biofeedback therapy. The muscular tension is estimated by solving the optimization problem from joint torque of each examinee´s joint during training. This paper reports comparison and its discussion of joint torque of each joint derived by an examinee´s identified parameters of dynamic equation and parameters determined by the average of about 100 peoples. The accuracy of the joint torque is improved by the identified parameters
