Fig. 4. Knee (
knee) and ankle (
ankle) joint
angles during the two subsequent stance phases. (A,C) Both knee and ankle do
not adapt in preparation for the following step as the mean values are within
the mean area ±1 s.d. of the reference run. (B,D) Both adapt in the
disturbed second contact as the initial contact joint angle
(
knee,TD,
ankle,TD) as well as the minimum
joint angle (
knee,min,
ankle,min) decrease.
For detailed values see Table
