Figure 3

Muscle activation patterns of 1 l trunk movement tasks. The concatenated EMG envelope of 1 l trunk stability and movement tasks is shown. The mean of the EMG envelopes for 16 participants is plotted as a line and the standard deviation as a shading around it. The amplitude is normalized to the maximum value for each muscle over all tasks and standardized to have a unit variance to equally weight the EMG activity across all muscles before each synergy extraction procedure.
