Figure 1.

Schematic representations of the logics of our procedure. (A) Sketch of the kinematics of five joints during the execution of a center-out movement to target P4 (referred to as task T4 in the following). (B) EMG signals from 9 muscles are recorded in each trial with surface EMG devices during movement execution. (C) Muscle synergies are extracted from the whole dataset and the corresponding synergy parameters are computed for each trial. (D) We finally decode which motor task is performed in each trial from the extracted synergies and activation coefficients.
