Performance in the force pulse phase. (a) Polar plot of the maximum distance (cm) the hand moved as a function of the force pulse direction. Data show mean ± s.e.m. across participants. (b) Global EMG before (left) and after (right) the force pulse for the stiff (red) and relaxed (blue) groups. Data show mean ± s.e.m. across participants.
