Fig. 7.

Activity of selected limb muscles during 3 complex locomotion tasks. A: typical examples of the averaged activity patterns of muscles whose activity was related to accuracy demands. Each panel shows a representative activity of an individual muscle, which was averaged over 10–25 strides of each locomotion task, all recorded during one session (see methods for stride selection). SDs were similar across all tasks and for clarity are shown for ladder-18 task only. B: typical examples of the averaged activity patterns of flexor and extensor fore- and hindlimb muscles whose activity was not related to accuracy demands.
