摘　　要：目的:探讨神经电生理检测对非典型腕管综合征(CTS)的诊断价值。方法:对16例CTS患者测定双侧正中神经运动传导速度(MCV)和感觉传导速度(SCV),其中14例用微移法(inchingtechnique)检测腕部正中神经,13例行肌电图(EMG)检查。结果:16例CTS患者中,15例正中神经末端运动潜伏期(DML)延长(≥4.5ms);14例SCV减慢(<46m/s);14例微移法检测患者均有腕部正中神经传导阻滞(≥0.5ms/cm);13例肌电图检测患者中8例有神经源性肌电改变。正中神经微移法检测是4项检查中最为敏感的指标。结论:在临床症状不明显时,神经电生理检查是发现和诊断CTS最有效的方法之一。Objective To study the role of electro-neurophysiological examination in the diagnosis of atypical carpal tunnel syndrome (CTS). Methods Motor conductive velocity (MCV) and sensory conductive velocity (SCV) of median nerve in 16 cases of CTS were determined. Fourteen patients were examined by inching technique of median nerve, and 13 were examined by electromyography. Results In 16 detected cases, distal motor latency (DML) of median nerve prolonged (≥4.5 ms ) in 15 cases; SCV decreased (<46 m/s) in 14 cases. All the 14 cases detected by inching technique had wrist median nerve conducting block (>0.5 ms/cm). In 13 patients detected by electromyography, 8 had abnormality of nervous electromyography. Inching detection of median nerve was the most sensitive method in the 4 methods above mentioned. Conclusions Electro-neurophysiological examination is one of the most effective methods in detecting atypical carpal tunnel syndrome.
