目的 探讨腓总神经麻痹患者肌电图及神经电图改变与临床症状、体征不一致的原因。方法 对 7例腓总神经麻痹患者的 14条腓总神经及腓肠神经分别进行运动传导速度 (MCV)、感觉传导速度(SCV)以及两侧胫前肌、腓肠肌及股四头肌等进行肌电图 (EMG)测定。结果 患侧腓总神经MCV潜伏期延长 ,传导速度减慢 ,复合肌肉动作电位 (CMAP)波幅降低 ;同时患肢胫前肌EMG有不同程度的失神经电位 ,但肌电图及神经电图改变与临床症状及体征的严重程度不完全一致。结论 腓总神经麻痹患者临床表现与神经电图不一致原因复杂 ,但肌电图及神经电图检查仍是诊断腓总神经麻痹的一种主要辅助检查手段。
Objective To investigate the causes of the change of electromyogram and electroneurogram in patients with common peroneal nerve paralysis and clinical symptoms and signs. Methods The mean arterial conduction velocity (MCV), sensory conduction velocity (SCV), and the anterior tibialis anterior muscle, gastrocnemius and quadriceps muscle of 7 common peroneal nerve and sural nerve in 7 patients with common peroneal nerve palsy were observed. Electro-graphic (EMG) determination. Results The latency of MCV in the common peroneal nerve was prolonged and the conduction velocity was slowed down and the amplitude of compound muscle action potential (CMAP) was decreased. Meanwhile, EMG of the anterior tibialis anterior limb muscle had different degree of denervation potential. However, the change of EMG and electromyography Clinical symptoms and signs of the severity is not exactly the same. Conclusions The causes of inconsistency between the clinical manifestation and EPG of patients with common peroneal nerve palsy are complex. However, EMG and neuroelectrongraphy are still the main auxiliary examinations for the diagnosis of common peroneal nerve paralysis.
