简介:目的将为第三腰部的横向的过程症候群观察不同频率的electroacupuncture(EA)的临床的效果。有第三腰部的横向的过程症候群的80个盒子全部的方法A被使随机化进二个组,40在每个组。Ashi点在中等频率的electroacupuncture(EA)与K8832-T处理设备被连接组织,而Ashi点在传统的EA组与G6805-2电的激发器被连接。药品效果在10个处理会议以后被评估。结果在中等频率的EA组的治疗学的功效比传统的EA组的显著地好(P<0.05)。另外,在中等频率的EA组的管分数的改进比传统的EA组的更著名(P<0.05)。中等频率的EA是为第三腰部的横向的过程症候群并且因此值得推广有益于病人的容易、有效的治疗的结论。
