脊髓灰质炎又称小儿麻痹症

属中医“痿症”

是由脊髓灰质炎病毒损害脊髓前角细胞而致的急性传染病。临床上常因无特殊和及时的治疗

留有四肢或单肢肌肉弛缓型瘫痪后遗症。我们通过应用电排针治疗脊髓灰质炎后遗症1000例的临床观察

结果基本痊癒369例

显效340例

好转260例

无效40例

总有效率为96%

发现疗效与病情

病程有明显的反比关系

与疗程成正比

与年龄关系不明显

发现疗效与主要的瘫痪肌肉有关

说明电排针治疗脊髓灰质炎确有一定疗效。为了进一步明确疗效

本研究应用肌电图检查作为脊髓灰质炎的诊断和疗效观察的客观指标

现总结如下:We observed the changes of quadriceps femoris EMG before and after treatment on treatment 41 cases of poliomyelitis sequelae with series electro-acupuncture.In 41 patients muscles strength of quedriceps femoris before treatment in 35 cases was below 0 degree and 1 degree.The changes of EMG

Most had no motor unit potential

some only a few but duration was long

and amplitude decreased markedly.A few had fibrillation or positive sha(?)p wave.The changes in EMG accorded with the diagnosis of poliomyelitis sequelae. After 3 month treatment

tee EMG findings were decreasing or there was loss of fibrillation

appearance of motor unit potentials

increase of the amount of motor unit potentials

prolongation of duration and increasing of amplitude of motor unit potentials

appearance of polyphasic potentials etc. Through analysis of EMG

32 among 41 cases were improved

effective rate was 78%

P<0.01.EMG indices indicate the efficacy of seriesmg electro-acupuncture in treating the sequelas of poliomyelitis and confirm the clinical therapeutic effect of the treatment.The indices indicate that the pathological changes of damaged anterior horn cells of the spinal cord were decreased and partial recovery of nervous function.The EMG changes paralleled those in clinical therapeutic effect of treatment and changes of muscle strength.
