Figure 3.

Reference synergies extracted during BL. Four unilateral synergies were extracted for both the left and right legs (A). Weights for each synergy are represented as average and standard deviation across the two experiments of all the subjects. The activation patterns are represented both individually (thin lines) and as an average across the two experiments of all subjects (bold line). Shaded areas represent the swing phase of the left (green) and right (grey) gait cycles, respectively. Four muscle synergies were also extracted in the bilateral analysis (B) that appeared to result from the combination of the unilateral synergies.
