摘　　要：目的分析无创性神经传导技术在振动性神经病中的应用价值。方法采用随机抽样的方式,在某磨光车间随机抽取从事手传振动作业工人15名作为观察对象,应用Nicolet viking quest神经肌电图机,分别采用传统针电极、皮肤表面电极两种记录方法对同一观察对象进行神经传导功能的检查,对比分析左右正中神经、尺神经运动传导末端潜伏期、波幅及传导速度有无差异。结果两种记录方法所得结果中,左侧正中神经运动传导波幅、右侧正中神经运动传导末端潜伏期差异有统计学意义(P<0.05),但参照北京协和医院的正常参考值,差异不影响对诊断结果的判断;其余差异均无统计学意义。可认为采用两种记录方法所得到的15名观察对象的神经电图检查结果全部一致。结论表面电极可以取代针电极,无创性神经传导功能检查在振动性神经病的临床诊治方面有较为广阔的应用前景。Objective To analyze the clinical value of non-invasive nerve conduction examination in diagnosis of vibration- induced neuropathy. Methods A total of 15 workers exposed to hand-arm vibration in a polishing workshop were randomly selected as the observation object. The Nicolet Viking quest electromyography was applied to examine nerve conduction function with traditional needle electrodes and the skin surface electrodes respectively. The results getting from these two methods were compared, including the conduction distal latency, amplitude and conduction velocity of median nerve and ulnar motor nerve of both sides. Results There were statistical differences in the amplitude of the left median nerve CMAP and distal motor latency of right median nerve after compared with two teams （P 〈 0.05 ）. However, the differences didn＇t affect the diagnosis according to the normal reference value recomnended by Peking Union Medical College Hospital, and the other inspection data had no significant differences （P 〉 0.05） . It could be considered that the results of 15 subjects showed there was no difference between using traditional needle electrodes and skin surface electrodes. Conclusion Surface electrodes can replace the needle electrode. Noninvasive nerve conduction function examination in clinical diagnosis of vibration neuropathy has a broad application.
