In order to simplify the procedure of its execution in our pendulum-test, an examiner had supported the lower-leg of the subject in a sitting situation manually until just before its start. The supporting force had however been apt to remain for a short time after its start. This study analyzed the influence of the residual supporting force on the lower-leg motion. It was assumed that the residual force decreased linearly with time. A simulator for the analysis was constructed by supplementing the function of the residual force to the existing one under such assumption. The influence on the lower-leg motion was investigated by comparing simulated waveforms with measured ones. Time when the force disappears was determined by means of reverse simulation of the measured waveform, so that both waveforms agreed as much as possible. As the results, the accuracy of the simulator increased dramatically.
