Motor Evoked Potentials after Supraspinal Stimulation in Pre- and Postoperative Evaluations of Patients with Cervical Radiculopathy

Table 3

Correlation (Spearman’s rank correlation coefficient rs) between root conduction time parameter (RxCT), RxMEP latency, and F conduction time (FCT). Recordings from the MEP abductor pollicis brevis muscle (APB) and abductor digiti minimi muscle (ADM) were compared.

	N	muscle		p
RxCT vs. RxMEP latency	35	APB	-0.17	0.4032
	35	ADM	-0.23	0.2468
RxCT vs FCT	35	APB	0.33	0.0898
	35	ADM	0.32	0.1008
