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
