对１２例格林─巴利综合征患者进行磁刺激运动诱发电位（ＭＥＰ）测定，记录电极分别放置在肢体近端肌肉（三角肌、肱二头肌、股四头肌）及远端肌肉（小指展肌、胫前肌）上，将二者的结果相比较，并与同时进行的肌电图、神经传导速度、Ｆ波进行比较，发现ＭＥＰ阳性率最高，利于早期发现病变；肢体近远端记录的ＭＥＰ阳性率相近，但近端ＭＥＰ对以近端无力为主的ＧＢＳ患者更为敏感。
Magnetic induction motor evoked potentials (MEP) were measured in 12 patients with Guillain-Barre syndrome. The recording electrodes were placed on the proximal limb muscles (deltoid, biceps, quadriceps) and distal muscles Muscular and tibialis anterior muscle), compared with the results of the two, and compared with simultaneous EMG, nerve conduction velocity, F wave, and found that the highest positive rate of MEP, which will help early detection of lesions; limbs near and far The positive rates of MEP were recorded, but the proximal MEP was more sensitive to GBS patients with mainly proximal weakness.
