Figure 4From: Changes in the activation and function of the ankle plantar flexor muscles due to gait retraining in chronic stroke survivorsChange in PF activation vs. peak knee flexion from pre- to post-intervention (A). Post-training forward center of mass acceleration by the plantar flexors vs. post-training self-selected walking speed (B). Change in plantar flexor percent activation vs. change in self-selected walking speed from pre- to post-intervention (C).Back to article page
