银质针治疗腰椎间盘突出症的临床肌电图观察

ELECTROMYOGRAPHY BEFORE AND AFTER SILVER NEEDLE ACUPUNCTURE TREATMENT IN PATIENTS WITH PROTRUSION OF THE LUMBAR INTERVERTEBRAL DISC

摘要:

本文对１２例腰椎间盘突出症采用银质针刺疗法治疗前后进行腰部骶棘肌临床肌电图对照检查，以观察该症引起的腰部神经肌肉功能变化与治疗效果的关系。结果提示治疗前全部病 有自发性电活动，经银质针疗法后７例减少，４例消失，３例患者治疗前运动单位平均时限低于正常的８０％，为肌源性损害表现，治疗后全部恢复正常；６例患者治疗后一周检查最大用力收缩动作电位出现混合相，单纯混合相、单纯相波形，与治疗后临床出现短暂的下肢

Abstract:

Patients with protrusion of the lumbar intervertebral disc were examined by electromyogram (EMG) before and after silver needle acupuncture treatment. Changes of the patients' neuromuscular function were observed. All patients' spontaneous potential were decreased or vanished after treatment. Three patients with marked decrease of the duration of motor unit potential were found to restore to normal level. Mixed pattern or mixed simple patterns of electromyogram were observed 1 week after treatment in 6 patients, which was in accord with the transient lower limb myasthenia. We thought that the result of EMG follow up study could reflect changes in neuromuscular function, and explicit the recovery of the protrusion of the lumbar intervertebral disc, therefore has considerable clinic value. Silver needle acupuncture treatment has notable effect on patients with chronic extravertebral soft tissue lesion, particularly its long term loosening effect on myospasm. The mechanism of acupuncture treatment needs further study.
