针刺委中穴对脑梗死后患者坐骨神经体感诱发电位的影响

Influence of acupuncturing acupoint Weizhong on somatosensory evoked potential in patients with ischemic stroke

目的观察针刺委中穴对脑梗死后患者坐骨神体感诱发电位(P40)潜伏期的影响。方法选择100例脑梗死患者,随机分为浅刺组25例(进针0.5寸)、深刺组25例(进针1寸)、过深刺组25例(进针1.5寸)及对照组25例。28d为1个疗程。疗程结束后,以体感诱发电位潜伏期变化为客观评价指标,对数据进行统计学处理。结果治疗前各组患者患侧SEP的P40差异无统计学意义(P>0.05),治疗结束后针刺组能使患者的P40潜伏期缩短,与对照组相比,各组差异有统计学意义(P<0.05)。针刺的深度对患者体感诱发电位P40无明显影响。结论针刺委中穴能使中风患者肢体SEP的P40潜伏期明显缩短。

Objective To study the influence of acupuncturing acupoint Weizhong（BL40） on the latency P40 of somatosensory evoked potential（SEP） in patients with ischemic stroke. Method All 100 patients with ischemic stroke were divided randomly into control group, superficial puncture group puncturing BIA0 0.5 inch, deep puncture group puncturing BIA0 1.0 inch and over-deep puncture group puncturing BL40 1.5 inch, 25 patients per group. After the treatment, SEP was used as the evaluation index. Results Before the treatment, the differences of SEP P40 on diseased side between groups were not statistically significant（P〉0.05）; after the treatment, the latencies of SEP P40 in all treatment groups were shortened compared with control group （P〈 0.01）. Conclusions Acupuncture in BL40 on the affected limbs can significant shorten the latencies of P40.
