Figure 3. Mean ± standard deviation of the medio-lateral avoidance displacement (A), the medio-lateral COM trajectory (B), and the rotation angle on the vertical axis of trunk, pelvis and foot (C) during walking and avoiding from moving or stationary walker. The * symbol indicates a significant difference between avoidance strategies from moving and stationary walker.
