The classical electromyographic investigations and simultaneous recordings of voluntary activity and M responses from muscles of both the upper and lower branch of the facial nerve were carried out in 5 patients with Bell's palsy. R1 responses were also recorded. All investigations were extended to the healthy side. With the aim of localizing the point of axonostenosis with axonal atrophy we investigated the following parameters: conduction velocity (c.v.) in the fallopian canal, c.v. in the external facial nerve, side difference of R1-M. In one case of amyotrophic lateral sclerosis with previous Bell's palsy signs of collateral sprouting and of ephaptic transmission were detected.
对5例贝尔麻痹患者进行了经典肌电图检查，并同时记录了面神经上下支肌肉的随意活动和M反应。还记录了R1反应。所有检查均扩展至健侧。为了定位伴有轴突萎缩的轴突狭窄点，我们研究了以下参数：面神经管内的传导速度（c.v.）、面神经外的传导速度、R1-M的侧别差异。在1例既往有贝尔麻痹体征的肌萎缩侧索硬化症患者中，检测到了侧支发芽和假突触传递的迹象。
