107例腕管综合征患者神经肌电图与临床分析

Analysis of the Clinical features and Electroneuromyography Significants in 107 Patients with Carpal Tunnel Syndrome.

目的探讨腕管综合征的神经肌电图表现及其与临床表现的相关性,以明确其神经肌电图对腕管综合征的诊断价值。方法回顾性分析107侧腕管综合征患者的神经肌电图检查结果和临床表现。结果腕管综合征患者拇指和中指至腕的正中神经感觉神经传导速度分别为36.2±5.6和36.5±5.5m/s,其阳性率分别为90.4%和86.7%,正中神经运动电位潜伏期平均为5.8±1.7ms,其阳性率为81.5%,46块拇外展肌记录到2处及以上纤颤电位或正尖波(34.1%)。结论神经肌电图检查对早期发现和诊断腕管综合征有重要意义。

Objective To explore the relationship between the clinical features and electroneurophysiological features in patients with carpal tunnel syndrome （CTS）,and to definite the diagnostic value of electronueromyography in CTS.Methods Retrospective analysis of the results of electronueromyography and clinical features in 107 patients with CTS was carried out.Results The sensory nerve conduction velocities of median nerve from thumb and middle finger to wrist in patients with CTS were 36.2 ± 5.6 and 36.5 ± 5.5m/s respectively,and their positive rate were 90.4% and 86.7%.The distal motor latency of median nerve in patients with CTS was 5.8 ±1.7ms,and its positive rate was 81.5%.The abnormality rate of fibrillation potential or positive sharp wave was 34.1%.Conclusion The electronueromyography examination has important implications for earlier detection and diagnosis of CTS.
