Figure 1.

Experimental stages for single-intervention and sequentially combined trials. Each experiment involved 23 min of uninterrupted walking, including 15 min of training. Baseline and post-adaptation stages did not involve rhythmic cues, and lasted for 3 and 5 min, respectively. Average asymmetry during late adaptation was obtained over 15 strides before the end of adaptation (demonstrated in blue hatch patterns), and average asymmetry during early post-adaptation was obtained over 15 strides after the beginning of the post-adaptation stage (demonstrated in green crosshatch pattern).
