It was the objective of our study to find a simple and reliable method for the electroneurographic examination of the sural nerve of patients suffering from polyneuropathy. As a first step, the normal values of persons not affected by this disease were taken by orthodromic technique and surface electrodes. The results were as follows: nerve conduction velocity: 59,44 m/s +/- 5,05; amplitude of the nerve action potential: 6,58 microV +/- 3,05; duration of the amplitude: 2,08 ms +/- 2,7; prolongation of latency after double stimulation: 3,37% +/- 0,77. Then potentials were stimulated by surface- and needle electrodes on the patients affected by polyneuropathy and recorded. Comparing the results gained by the different methods, we found that they correlated in a highly significant way, which means that all the methods are equally applicable. The stimulation and recording by surface electrodes, however, has apart from its reliability the additional advantage of being a simple, quick, and gentle method of examination. There is little objection to applying it repeatedly to the same patient. Further information about polyneuropathy can be obtained by the examination of the relative refractory period.
我们研究的目的是找到一种简单可靠的方法，用于对患有多发性神经病患者的腓肠神经进行神经电图检查。第一步，采用顺向技术和表面电极获取未患此病者的正常值。结果如下：神经传导速度：59.44米/秒±5.05；神经动作电位幅度：6.58微伏±3.05；幅度持续时间：2.08毫秒±2.7；双刺激后潜伏期延长：3.37%±0.77。然后，用表面电极和针电极刺激患有多发性神经病的患者并记录电位。比较不同方法获得的结果，我们发现它们具有高度显著的相关性，这意味着所有方法同样适用。然而，表面电极刺激和记录除了具有可靠性外，还具有简单、快速且温和的检查方法这一额外优点。对同一患者反复应用该方法几乎没有异议。通过检查相对不应期可获得有关多发性神经病的更多信息。
