More push from your push-off: Joint-level modifications to modulate propulsive forces in old age - Fig 5

<p>Group average hip and ankle joint powers by condition across time for RR_Low (left) and RR_High (right). Dashed grey lines represent young preferred walking as reference. An X on each curve provides a reference for the timing of peak F_P. Asterisks (*) represent a significant main effect (p<0.05) of F_P biofeedback on peak hip power during early stance (i.e., H1) and push-off (i.e., H3) and on peak ankle power.
