本文对20例格林-巴利综合征(GBS)病人进行了肌电图(EMG)、运动、感觉传导速度(MCV、SCV)及F潜伏期的测定。测了70块肌肉的EMG,发现EMG能诊断神经源性损害者占90％;测了125条MGV及58条SCV,MCV减慢占66.4％,其均值比正常人下降24.3～37.8％,SCV减慢占51.7％,其均值比正常人下降13.4～22.2％,这反映了GBS病人的周围神经脱髓鞘特点,运动神经的末梢潜伏期减慢占48.5％,感觉神经的未梢潜伏期减慢占83.3％。其次,测MCV时的诱发电位波幅高下降占88.9％,这项指标变化明
In this study, electromyography (EMG), motor, sensory conduction velocity (MCV, SCV) and F latency were measured in 20 patients with GBS. The muscle EMG of 70 muscles was measured and found that EMG can diagnose neurogenic damage accounted for 90%; measured 125 MGV and 58 SCV, MCV slowed down accounted for 66.4%, the mean decreased 24.3 ~ 37.8% than normal, SCV Slowed down 51.7%, the mean decreased 13.4 ~ 22.2% than normal, which reflects the characteristics of GBS patients with peripheral nerve demyelination, nerve endings slowed down the latency accounted for 48.5%, sensory nerve of the slow decline in latency 83.3%. Second, the measured amplitude of evoked potential amplitude of MCV decreased 88.9%, the indicators change
