Results of processed sEMG signals and US imaging-derived MT signals from both LGS and SOL muscles during the treadmill walking experiments at different speeds on Participant Sub01. The mean and one SD values of the plantarflexor muscles on the right shank during recorded stance phase cycles (from the heel-strike instant to the toe-off instant in the same gait cycle) are represented by the solid lines and the light shadowed areas, respectively
