Fig. 2From: Paretic versus non-paretic stepping responses following pelvis perturbations in walking chronic-stage stroke survivorsPositions of the COM of the feet relative to the whole body COM. a Locations of the COM of both the leading and the trailing foot relative to the whole-body COM, at the instant of heel strike, for steps made with the paretic leg. b Same as in A, for steps made with the non-paretic leg. Triangles show subject averages and indicate the perturbation direction. Ellipses represent subject standard deviations. Colors indicate the perturbation magnitudes as a fraction of the subject’s body weightBack to article page
