Evaluating Significance of Guilain-Barre Syndrone in Electrophysiological Detection

Objective To study the distribution and lessions degree of electrophysiological abnormalities of patients with GBS and evaluate and appraise its significance. Methods Fifty-four patients received electrophysiological examination.Distal motor latency(DML),motor conduction velocity(MCV),compound muscle action potential(CMAP) and sensory conductive velocity(SCV) were recorded. Results The abnormal rate of MCV(77.0%) was higher than of SCV(59.4%)(χ2=5.115,P0.05);DML of distal muscles were the same as that of proximal muscles;DMLof muscles of upper limbs were epuly with that of lower limbs;The severe lesion rate of DMLof distal muscles(75.6%) was higher than that of proximal muscles(47.4%)(χ2=14.62,P0.01).Conclusion Electrophysiological changes of GBS are extensive.The motor nerve is easier to be damaged than sensory nerve,and the damage degree is more severe on distal nerve than proximal nerve.
