Muscle responses evoked distally and proximally were recorded in median and in peroneal nerves from controls and patients with polyneuropathies of different origin. The following parameters were studied in the individual muscle response: 1. the amplitude of the potential, measured peak to peak, 2. the amplitude of the negative phase, 3. the total duration of the potential, 4. the duration of the negative phase, 5. the area covered by the negative phase. Results of the proximal measurements were divided by those of the distal records. Distal motor latencies and nerve conduction velocities were also determined. In controls a loss of amplitude of 10-15% and an equal reduction of the area covered by the negative phase was noted in proximally evoked responses and the duration of the negative phase was increased by 2-7% when compared with distal measurements. In some polyneuropathies these parameters showed significantly pathological changes, although distal motor latency, amplitude and nerve conduction velocity were still within the normal range. Comparison of distally and proximally evoked muscle potentials may thus lead to further information about the mode of conduction in altered motor nerves.
在对照组以及患有不同病因多发性神经病的患者的正中神经和腓总神经中，记录了远端和近端诱发的肌肉反应。在个体肌肉反应中研究了以下参数：1. 峰峰值测量的电位幅度；2. 负相的幅度；3. 电位的总持续时间；4. 负相的持续时间；5. 负相覆盖的面积。近端测量结果除以远端记录结果。还测定了远端运动潜伏期和神经传导速度。在对照组中，与远端测量相比，近端诱发反应中观察到幅度损失10 - 15%，负相覆盖面积同等减少，负相持续时间增加2 - 7%。在一些多发性神经病中，尽管远端运动潜伏期、幅度和神经传导速度仍在正常范围内，但这些参数显示出明显的病理变化。因此，比较远端和近端诱发的肌肉电位可能会获得有关改变的运动神经传导模式的更多信息。
