Abstract: Objective To explore the effect of electroacupuncture and transcutaneous electrical acupoint stimulation (TEAS) on somatosensory evoked potential (SEP) of the upper extremity in healthy subjects. Methods From October, 2015 to April, 2016, ten healthy young volunteers were selected. Each of the subjects was randomly treated with electroacupuncture and TEAS. Before and after treatment, the latency and amplitude of N20 and N9 of SEP were detected. Results After electroacupuncture, the latency of N20 prolonged in the stimulated side (Z=-2.620, P<0.01); the latency of N9 prolonged (Z=-2.454, P<0.05), and the amplitude of N9 decreased (Z=-2.330, P<0.05) in the non-stimulated side. After TEAS, the latencies of N9 both in the stimulated side and the non-stimulated side prolonged (Z>2.695, P<0.01). There was no significant difference in the D-value of latency and amplitude of N20 and N9 in both two sides between two treatments (Z<1.817, P>0.05). Conclusion Both electroacupuncture and TEAS could affect the latency and amplitude of N20 and N9, and no difference was found between two treatments.

Key words: electroacupuncture, transcutaneous electrical acupoint stimulation, somatosensory evoked potential
