他動底背屈時における足関節粘性トルクの推定

抄録

A model has been proposed to represent the relationship between ankle joint angle and ankle joint torque during passive motion using time-varying elastic modulus. The method assumes the viscosity term to be zero. This leads to modelling errors when the ankle joint is in passive motion at high angular velocities. In this study, a viscous term is added to this model. The validity of the proposed model was evaluated by showing that under experimental conditions with different angular velocities, the elastic torque obtained by subtracting the value of the viscous torque estimated using the identification model from the viscoelastic torque is almost identical.
