...Sarah N. Fickey; Michael G. Browne; Jason R. Franz ABSTRACT The plantarflexor muscles are critical for forward propulsion and leg swing initiation during the push-off phase of walking, serving to modulate step length and walking speed. However, reduced ankle power output is common in aging and gait...
