Nowadays, aging is rapidly proceeding in Japan. We can predict that there will be many accidents of falls of the elderly. So we pay attention to the prevention of falling. In this paper, we model quiet posture with simple inverted pendulum model and identify ankle viscoelasticity during quiet stance using sway of the center of pressure measured by force plate. We examined the change of ankle viscoelasticity when the subject's visual conditions were changed or the ankles were stretched. Visual conditions were open eyes, closed eyes, and biofeedback of the center of pressure. While we found that sway of center of pressure increased as the result of change of visual conditions and ankle joints stretching, we found that ankle viscoelasticity did not change.
