【摘要】：目的观察电针和经皮穴位电刺激(TEAS)前后体感诱发电位(SEP)的变化。方法 2015年10月至2016年4月本科实习生10例,采用自身前后对照研究,每例受试者均随机接受电针和TEAS治疗,间隔1周。治疗前后检测SEP的N20、N9潜伏期及波幅。结果电针治疗后,刺激侧N20潜伏期明显延长(Z=-2.620,P0.01);非刺激侧N9潜伏期延长(Z=-2.454,P0.05),N9波幅降低(Z=-2.330,P0.05)。TEAS治疗后,刺激侧和非刺激侧N9潜伏期均明显延长(Z2.695,P0.01)。两组治疗前后刺激侧及非刺激侧N20和N9潜伏期、波幅差值均无显著性差异(Z1.817,P0.05)。结论单次电针及TEAS治疗均可对SEP的N20、N9潜伏期及波幅产生影响,两种治疗对SEP的影响组间无明显差异。
[Abstract]:Objective to observe the changes of somatosensory evoked potential (SEP) before and after electroacupuncture and transcutaneous electrical stimulation of (TEAS). Methods from October 2015 to April 2016, 10 intern students were treated with electroacupuncture and TEAS at random, with an interval of 1 week. The N 20 N 9 latency and amplitude of SEP were detected before and after treatment. Results after electroacupuncture treatment, the incubation period of N20 in the stimulatory side was significantly prolonged (ZF- 2.620, P0.01), while in the non-stimulative side, the latency of N9 in the non-stimulative side was prolonged (P05). The amplitude of N9 in the non-stimulative side was decreased (ZTEAS, P0.05). After treatment, the latency of N9 in both the stimulative and non-stimulative sides was significantly prolonged (Z2.695, P0.01). There was no significant difference in the latency and amplitude of N20 and N9 between the two groups before and after treatment (Z1.817 P 0.05). Conclusion both single electroacupuncture and TEAS can affect the N20N9 latency and amplitude of SEP, but there is no significant difference between the two groups.
