Onset latency and amplitude of the movement of the foot, and latencies and durations of the EMG bursts in the leg movement task

Measurement	Control	Test
Onset latency of footMOV	237.6 ± 98.0	122.6 ± 25.3*
Magnitude of footMOV	209.2 ± 92.8	244.1 ± 102.5
Onset of pmsp in TRS	130.2 ± 46.8	68.5 ± 8.4*
Duration of pmsp in TRS	114.6 ± 57.1	60.9 ± 17.0*
Interval from onset of pmsp to onset of the TA burst	54.2 ± 22.2	46.2 ± 11.1
Duration of TA burst	81.8 ± 32.7	77.9 ± 12.4
Interval between EMG onset in TA and EMG onset in TRS	62.0 ± 18.1	53.3 ± 16.0

Values are the mean ± S.D. of the measurements listed in the left column. FootMOV, foot movement; TRS, triceps surae; TA, tibialis anterior; pmsp, premovement silent period. All data are given in milliseconds, except for amplitude of foot movement, which is given in arbitrary units.
