Fig. 8

Kinematic data for late swing perturbation lowering strategy responses. Each plot depicts a different kinematic variable with the first row depicting the contralateral limb (i.e., support limb) hip, knee and ankle angle from left to right, the second row depicting ipsilateral limb (i.e., perturbed limb) hip, knee, and ankle angle from left to right, and the third row depicting ipsilateral thigh frontal plane angle (i.e., abduction) and trunk sagittal plane angle from left to right. Warm colored lines (red and yellow) depict non-MPK users and cool lines (cyan, purple, blue and green) depict C-Leg users. Solid lines represent a successful recovery, while dashed lines represent a fall. The red circle represents when the perturbation occurs, the black circles represent heel strikes, the black rings represent toe offs, and the red rings represent when a fall occurs
