Table 1. The PMCT, latency of MEPs, and CMCT of bilateral limbs pre-operation.

	Upper limb				Lower limb
	PMCT (ms)	Latency (ms)	CMCT (ms)		PMCT (ms)	Latency (ms)	CMCT (ms)
Left	13.5	24.1	10.6		14.0	42.3	28.3
Right	13.6	23.5	9.9		15.0	41.7	26.7

PMCT, peripheral motor conduction time; MEPs, motor evoked potentials; CMCT, central motor conduction time.
