Results of electroneuromyographic examinations of 207 patients with hereditary neuromuscular diseases are presented. Patients with neural amyotrophies showed a sharp slowdown of the speed of impulse transmission along the median and the tibial nerves, a lowering of the induced potentials of the muscle and the nerve, and an increase of the M-response. In patients with spinal amyotrophies a slight lowering of the speed of the impulse transmission along the tibial nerves with the transmission speed along the median nerves being normal, a diminution of the amplitude and a shortening of the duration of the M-response, and an increase of the amplitude of the nerve action potentials were revealed. Patients with myodystrophies exhibited a slowdown of the speed of impulse transmission along the afferent fibres, and increase of the motosensor coefficient, a moderate lowering of the maximal with a tendency to a heightening of the minimal amplitude of the M-response and the nerve action potential.
本文呈现了207例遗传性神经肌肉疾病患者的肌电图检查结果。神经源性肌萎缩患者表现出沿正中神经和胫神经的冲动传导速度急剧减慢、肌肉和神经诱发电位降低以及M反应增强。脊髓性肌萎缩患者表现出沿胫神经的冲动传导速度略有降低，而沿正中神经的传导速度正常，M反应的幅度减小、持续时间缩短，以及神经动作电位的幅度增加。肌营养不良患者表现出沿传入纤维的冲动传导速度减慢、运动感觉系数增加、最大M反应幅度适度降低且最小M反应幅度和神经动作电位有升高趋势。
