神经电生理检查对无明诱因足趾背伸功能障碍的诊断价值

THE DIAGNOSTIC VALUE OF NEURAL ELECTROPHYSIOLOGICAL EXAMINATION IN PATIENTS WITHOUT INCENTIVE TOE DORSIFLEXION DYSFUNCTION

目的:目的:探讨无诱因足趾背伸功能障碍的病因及电生理检查对其鉴别诊断的临床意义。方法:对100例无明显诱因致足趾背伸无力的患者进行电生理检查,内容包括腓总神经、胫神经、尺神经等运动神经传导速度(motor nerve conduction velocity,MNCV),腓浅神经、腓肠神经、尺神经感觉传导速度(sensory nerve conduction velocity,SNCV),腓总神经、胫神经、尺神经支配肌肌电图(electromyogram,EMG)。结果:100例中腓骨小头处腓总神经卡压17例,30例神经根受腰椎间盘压迫,42例多发性周围神经病,7例PMP22基因重复所致的CMT-1A型(HNPP),1例髂腹股沟处肿块卡压致高位坐骨神经损伤,1例脑部肿瘤患者。电生理检查所得结果阳性率为98%。结论:神经电生理检查可以为无明确诱因引起的足趾背伸无力患者提供客观的指标,对患者的病因诊断提供重要的参考价值。

Objective： To explore the disease＇s cause of no cause leading to toe dorsiflexion dysfunction and discuss the clinical significance of electrophysiological examination in the differential diagnosis. Methods： The electrophysiological examination was perfomed in 100 patients without incentive toe dorsiflexion dysfunction, including motor nerve conduction velocity （MNCV） for common peroneal nerve, tibial nerve and ulnar nerve, sensory nerve conduction velocity （SNCV） for superficial peroneal nerve, sural nerve and ulnar nerve, and electromyogram （EMG） on muscle for common peroneal nerve, tibial nerve and ulnar nerve. Results： Seventeen cases were of the head of fibula and common peroneal nerve compression, 30 cases nerve root compression of lumbar intervertebral disc, 42 cases polyneuropathy, 7 cases CMT-1A type PMP22 gene duplication, 1 cases high sciatic nerve injury caused by mass in the groin, and 1 cases patient with brain tumor. Conclusion： The Nerve electroneurophysiological examination can provide objective indicators for patients without incentive toe dorsiflexion dysfunction, with providing some important reference value for etiological diagnosis
