Timing and amplitude characteristics of poststimulus force responses and EMG facilitation and suppression. Onset latency is defined as the earliest time at which the EMG or force recording deviated from baseline activity by >2 ± SD. PStF, poststimulus facilitation; PStS, poststimulus suppression; TTP, time to peak.
