经络脉冲电刺激治疗腰椎手术失败综合征疗效及机理探讨

A study on electric acupuncture point stimulation for failed back surgery syndrome by pulsed stimulation

目的 :总结脉冲调制中频电刺激对腰椎手术失败综合征的治疗效果 ,探讨其治疗机制。方法 :用多电极脉冲调制中频电同时刺激腰背部及膀胱经委中等腧穴的方法治疗 35例腰椎手术失败综合征患者 ,并与仅刺激腰背部治疗的 2 6例进行对比观察 ,用“腰腿痛治疗成绩评分表”评定疗效。 2 0只家兔分为两组 ,分别将 10 %辣根过氧化物酶 10 0 μl注入兔后腿委中穴或兔一侧腰部 ,在镜下观察HRP标记细胞在腰骶后根神经节及脊髓的分布。 结果 :观察组有效率 94 3% ,对照组有效率 77% ,(P <0 0 5 )。动物实验发现兔委中穴的神经和腰背部肌肉神经投射到后根神经节和脊髓有相重叠部位。结论 :应用多电极脉冲调制中频电对腰腿部及足太阳膀胱经同时进行多穴位电刺激是一种较好的治疗腰椎手术失败综合征的方法 。

Objective:To make a inference of the therapy of failed back surgery syndrome (FBSS) in the light of the Theory of meridian and collaterals.Method:①Patients who had undergone lumbar disc surgery were treated as the case group with pulsed electric current in modulated medium frequency by the apparatus with 6-12 channels. The electrodes were put beside the lumbar vertebrates and on some related acupuncture points along foot taiyang bladder meridian, such as weizhong. The patients of control group were treated at the lumbar only. Then the curative effects were assessed by the Scale Table of Low Back Pain and compare the results between the two groups.②HRP, a neural tracer was injected into weizhong point and beside the lumbar vertebrates of rabbits separately,then examine the distribution of HRP in the spinal cords.Result:The rate of improvement of the case group was 94.3%.It was better than that of the control group and there was significant difference between the two groups ( P <0.05).The distribution of HRP injected from weizhong and the lumbar area was partly overlapping in the spinal cord.Conclusion:It is more effective to stimulate the lumbar area and foot taiyang bladder meridian simultaneously by pulsed current in modulated medium frequency than local therapy.The neurobiologic experiment can provide some evidence.
