TcMMEP Responses on Week 5

Displacement	Response rate (%)	Onset latency (msec)	Peak-to-peak amplitude (mV)
0 mm	100	6.3 ± 0.21	15.9 ± 5.3
0.2 mm	100	6.3 ± 0.24	3.9 ± 6.4**
0.4 mm	33.3***	6.2 ± 0.16	0.9 ± 0.8** (**)
0.6–1.2 mm	0***(***)	N/A	N/A

Data are the mean ± SD; n = 5–6/group. For response rate, ***p < 0.001 as compared to 0 and 0.2 mm displacement; ^(***)p < 0.001 as compared to 0.4 mm displacement. For amplitude, **p < 0.01 as compared to 0 displacement, ^(**)p < 0.01 for 0.4 mm compared to 0.2 mm displacement.
