对６３例临床确诊的格林－巴利综合征（ＧＢＳ）患者进行了连续电生理观察，发现与经典的ＧＢＳ不同。而本组病例表现，运动神经末端潜伏期、Ｆ波潜伏期、运动传导速度正常或轻微异常，运动诱发波幅明显降低，感觉传导速度和感觉神经电位正常，符合运动轴索的损害。病理证实为周围运动神经的瓦勒氏样变性。 63 cases of clinically diagnosed Guillain-Barre syndrome (GBS) patients were observed by electrophysiological changes and found that the classic GBS different. In this group of patients, motor nerve terminal latency, F wave latency, motor conduction velocity was normal or mild abnormalities, exercise-induced amplitude was significantly reduced, sensory conduction velocity and sensory nerve potential were normal, consistent with motor axonal damage. The pathology was confirmed by Wallerian-like degeneration of the surrounding motor nerves.
