1. CoP shift against initial CoP–XcoM distance, for all unperturbed strides of subject 1 (red dots and green crosses), for strides with a left push at 90% (red circles) and for strides with a right push at 40% (green squares).
CoP shift against initial CoP–XcoM distance, for all unperturbed strides of subject 1 (red dots and green crosses), for strides with a left push at 90% (red circles) and for strides with a right push at 40% (green squares). The negative slope of the points indicates that CoP shift by the ankle strategy partly compensates for inaccurate foot placement by the stepping strategy (see Discussion).
