Matched open-chain dorsiflexion movements with E-stim turned ON vs. OFF. Ankle dorsiflexion angle (top) and linear envelope of rectified vEMG from TA muscle (bottom) during an open-chain ankle movement task. The E-stim was turned off after 10 seconds (dashed vertical line). Note that for the same range and timing of ankle kinematics, the vEMG was lower with assistance from the aEMGcFES.
