【摘要】 作者观察了电排针治疗41例脊髓灰质炎后遗症的股四头肌肌电图在治疗前后的变化。在治疗前,其肌电图大多数没有运动单位或偶有少量运动单位,但电压低、时限宽;少数有纤颤电位、正锐波。3个疗程后,肌电图的纤颤电位减少或消失;重新出现运动单位;运动单位数量增加,电压增高,时限延长;出现多相电位等。肌电图好转者有32例,有效率为78％,且肌电图变化与临床疗效和肌力变化是一致的。更多还原

【Abstract】 We observed the changes of quadriceps femoris EMGbefore and after treatment on treatment 41 cases of poliomyelitis sequelae with series electro-acupuncture. Before treatment, the changes of EMG were that most had no motor unit potential, some only a few but duration was long, and amplitude decreased markedly, a few had fibrillation or positive sharp wave. After 3 month treatment, the 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 poly phasic potentials etc. Through analysis of EMG, 32 among 41 cases were improved, effective rate was 78%. The EMG changes paralleled those in clinical therapeutic eftect of treatment and changes of muscle strength.更多还原
