EMG activity, EMG latency and Angle latency.

	Experiment 1	Experiment 2	Experiment 3
EMG activity of muscles to be relaxed
TA	43.4 ± 9.9	44.2 ± 12.7	41.8 ± 8.7
SOL	40.2 ± 6.5	39.7 ± 11.0	40.8 ± 10.1
Each value was the root mean square in the 100 ms period just before auditory stimulus (%MVC)
EMG Latency of relaxation onset (ms)
TA	163 ± 32	155 ± 32	159 ± 35
SOL	168 ± 35	166 ± 28	171 ± 32
Angle Latency of relaxation onset (ms)
TA	221 ± 43	217 ± 44	220 ± 45
SOL	230 ± 47	225 ± 42	231 ± 47
