FIG. 2.

Kinematic data from the ipsilateral (left) hindlimb following injury during obstacle negotiation. Stick figures of one representative swing phase when the limb trajectory was not modified (A, other), during the stumbling corrective response (B), and during a complete clearance (C). Arrow indicates direction of movement (A–C). Waveform graphs depict post-injury changes in hip (D, E), knee (F, G), and ankle joints (H, I). Long-lasting changes in joint angles were seen even out to the most chronic time point (16 wks). The gray shaded area represents the position of the obstacle. The thin line indicates the division between stance and swing.
