We measured CoP and activity of the ankle muscles in several standing conditions. Those include (EO):eyes-open, (EC):eyes-closed, (EOvf):eyes-open with a constant visual feedback target, and (SWAY):the same as EOvf but with a sinusoidally varied target. We showed how the CoP sway patterns and the muscle activity changed depending on the standing conditions. Then possible mechanisms that can reproduce the observed sway and that can cause the condition dependent changes were interpreted using the PD controller model and/or the intermittent controller model. It was suggested that the control strategy during EO/EC condition was better interpreted by the intermittent model, whereas the control strategy changed from the intermittent to PD control as the standing condition changed from EO/EC to EOvf/SWAY. |
