摘要:

目的　探讨肌电图检查在足下垂神经损伤定位诊断中的临床价值。方法　选择2015年4月至2016年6月在新乡市中心医院就诊的足下垂患者32例为研究对象。应用表面电极检测腓肠神经、腓浅神经感觉传导速度（SCV）和波幅（AMP），腓总神经、胫神经运动传导速度（MCV）和AMP；肌电图检测腓总神经、胫神经、坐骨神经、臀上神经所支配的肌肉和腰椎旁肌。结果　32例患者中，腓总神经损伤18例，坐骨神经损伤5例，腰骶神经丛损伤4例，第5腰神经根损伤5例。腓总神经在腓骨小头处传导阻滞或MCV减慢17例，腓总神经远端AMP降低或伴MCV减慢16例，腓总神经波形缺失6例。胫神经AMP降低或伴MCV减慢14例。腓浅神经SCV减慢或伴AMP降低23例，腓肠神经SCV减慢或伴AMP降低9例。胫骨前肌损害32例，腓骨长肌损害21例，股二头肌短头损害14例，胫骨后肌损害14例，臀中肌损害9例，腰椎旁肌损害5例。结论　肌电图检测可明确足下垂的神经损伤部位，判断其损伤程度。

Abstract:

Objective　To explore the value of electromyography in localization diagnosis of neural damage of footdrop.Methods　Thirty-two patients with footdrop in Xinxiang Central Hospital from April 2015 to June 2016 were selected as research subjects.The sensory conduction velocity（SCV）and amplitude（AMP）of sural nerve，superficial peroneal nerve and the motor conduction velocity（MCV） and AMP of common peroneal nerve，tibial nerve was detected by surface electrode.The muscle which was innervated by common peroneal nerve，tibial nerve，sciatic nerve，superior gluteal nerve and lumbar paraspinal muscle was detected by electromyography（EMG）.Results　Among the 32 patients，there were 18 patients of common peroneal nerve injury，5 patients of sciatic nerve injury，4 patients of lumbosacral nerve plexus injury，five patients of the fifth lumbar vertebra nerve root injury.The conduction block or MCV slowness of common peroneal nerve in the fibular head was observed in 17 patients；the AMP reduction or MCV slowness of distal end of common peroneal nerve was observed in 16 patients；the waveform disappearance of common peroneal nerve was observed in six patients.The AMP reduction or MCV slowness of tibial nerve was observed in 14 patients.The SCV slowness or AMP reduction of superficial peroneal nerve was observed in 23 patients；the SCV slowness or AMP reduction of sural nerve was observed in 9 patients.Among the 32 patients，there were 32 patients of tibialis anterior muscle injury，21 patients of peroneus longus injury，14 patients of short head of biceps flexor cruris muscle injury，14 patients of tibialis muscle injury，9 patients of gluteus medius injury，5 patients of lumbar paraneal muscle injury.Conclusion　EMG detection can clearly identify the location of neural injury of footdrop and determine the degree of neural injury.
