Abstract
The purpose of this study is to establish a quantitative method that can evaluate the motor function of human lower limbs in dynamic situations. As an index of motor function, we focus on the mechanical impedance characteristics of the lower limbs. By controlling these characteristics, humans can improve motion stability and adapt their movement to disturbances in the environment. In this paper, validation was performed using our proposed method to estimate the impedance, whether the impedance is adjusted by changing load during pedaling exercise. In the result, the impedance was adjusted in preparation for changing load unlike in the case of constant load. This agreement suggests that our method could extract a component of human motor control strategy that adjust mechanical impedances during pedaling exercises.
