Abstract

19 ALS patients were submitted to motor evoked potentials (MEP) and F-wave from thenar muscles. Somatosensory evoked potentials (SEP) from median nerve were recorded as well in 16 patients. MEP were bilaterally absent in 4 patients (21%) and monolaterally absent in 6 patients (3.6%). Among patients with recordable waves, MEP and F-wave were significantly delayed. Their upper motor neuron conduction time was clearly abnormal only in one case. In SEP recordings the N9-N13 was significantly delayed, but the N13-N20 was normal. Four patients showed a combined sensory-motor dysfunction (increase of both N19-N13 interval and F-wave latency).

摘要

19例肌萎缩侧索硬化症患者接受了来自大鱼际肌的运动诱发电位（MEP）和F波检查。16例患者还记录了正中神经体感诱发电位（SEP）。4例患者（21%）双侧MEP缺失，6例患者（3.6%）单侧MEP缺失。在可记录到波形的患者中，MEP和F波明显延迟。仅1例患者的上运动神经元传导时间明显异常。在SEP记录中，N9 - N13明显延迟，但N13 - N20正常。4例患者表现为感觉运动联合功能障碍（N19 - N13间期和F波潜伏期均增加）。
