Four modules are sufficient to reconstruct the EMG envelopes of all the testing conditions with a VAF higher than 90%. Representation of this modular control is organized in three columns, one for each gait speed. Average and standard deviation of the EMG envelopes of the seven muscles (left). Average and standard deviation of motor modules (center). Activation signals (right), with thin gray lines representing the results of each subject of the study, and thick black lines representing the group average.
