Muscle Activation Patterns and Extracted Locomotor Muscle Synergies

In the left part, black lines indicate the averaged muscle activation patterns across participants during a gait cycle. Thick lines indicate the average temporal activation patterns, whereas thin lines indicate the SDs. In the right part, five extracted types of locomotor muscle synergies are shown. Average muscle weightings (bars) and corresponding temporal activation patterns (waveforms) across participants in each type of locomotor muscle synergy are shown. Each bar height represents the relative level of activation of each muscle synergy. An enlarged view of the x axis is shown at the bottom. Lines indicate the temporal activation patterns of the muscle synergies. Thick lines indicate average temporal activation patterns, whereas thin lines indicate their SD. See also Table S1.
