摘　　要：目的探讨腕尺管综合征的肌电图表现。方法对13例腕尺管综合征患者行肌电图检测,包括尺神经运动潜伏期、运动波幅、尺神经小指感觉传导速度、感觉波幅等,与其健侧对照比较,评估肌电图表现差异。结果腕尺管综合征患者其患侧肌电图与健侧比较,尺神经运动潜伏期延长(P<0.01),运动波幅缩小(P<0.01),尺神经小指感觉传导速度减慢(P<0.01)、感觉波幅缩小(P<0.01),小指展肌、第Ⅰ骨间肌肌电图也出现静息状态及重收缩状态的改变。结论腕尺管综合征患者存在肌电图的多项改变,早期检测对于其诊断及其治疗具有重要意义。Objective To explore the findings of electromyogram in patients with carpal ulnar tunnel syndrome. Methods The examination of electromyogram including motor latency and amplitude of motor wave of ulnar nerve digitus minimus manus, velocity of sensory conduction and amplitude of sensory wave of ulnar nerve digitus were examined in 13 patients with carpal ulnar tunnel syndrome, and they were compared with those of uninjured side and their discrepancy was evaluated. Results In comparison with uninjured side, the motor latency of ulnar nerve was significantly prolonged （ P 〈 0.01 ）, the amplitude of motor wave was significantly decreased （ P 〈 0.01 ）, velocity of sensory conduction of ulnar nerve digitus minimus manus was slower and amplitude of sensory wave was decreased （ P 〈 0.01 ）. There were changes in electromyogram in abductor digital minimal muscle and interosseal muscle in quiescent and recontract condition. Conclusion There are electromyographic changes in patients with carpal ulnar tunnel syndrome, and it is important to examine electromyogram for its diagnosis and treatment in patients with this syndrome.
