Results are expressed as medians (25-75% percentile). EMG (% of reference voluntary contraction), electromyography signals of paralytic dorsiflexor muscle, EMG signals of maximum voluntary isometric contraction/EMG signals of reference voluntary contraction); TUG (sec), timed up and go; 10 MWT (sec), 10 m walking test.
