| 摘 要： | 目的探讨平山病的临床及神经电生理特点。方法观察38例平山病患者的特殊临床表现,检测双侧上肢远端及下肢常规肌电图及周围神经传导速度。结果 38例患者均为青春期起病,病变均表现为上肢远端肌肉、骨间肌、鱼际肌萎缩和双手厥冷无力。肌电图检查示患者受累侧远端肌运动单位平均时限宽,多相波增多,波幅显著增高。结论平山病主要发生在青春期,临床表现和肌电图检查提示局限于下位颈髓的前角病变。

| Abstract: | Objective To investigate the clinical and electromyographic characteristics in patients with hirayama disease（HD）.Methods Special clinical features were observed,routine EMG and peripheral nerve conduction were detected on 38 HD patients.Results 38 patients were young men or women with asymmetric muscular atrophy and weakness of the hand and forearm.Concentric needle EMG revealed long duration,large amplitude polyphasic potentials with poor recruitment.Conclusion Hirayama disease occurs mainly in adolescent age,Clinical features and EMG cue that the lesions are mainly limited at anterior horn. |
