- Abstract
- The present study was designed to identify the sequential electrophysiological findings ant to determine the prognostic values of electrophysiological and clinical pararneters in patients with Guillain-Barre syndrome (GBS). Severely affected 42 subjects (Grade D,E). Who fulfilled the diagnostic criteria of GBS were selected. Twentynine patients were followed up at least 6 months (range 6-24 months) from the onset of neurologic syrnptorns. We analyzed 83 electrodiagnostic studies from 42 subjects. The sequential electrophysiological abnorrnalities were most marked at 3-4 weeks after the onset. At that time the most significant change was a decrease of CMAP amplitude. By stepwise discriminant analysis of several electrophysiological parameters, the three variables, of CMAP amplitude, distal conduction velocity; and F-wave latency were deterrnined to be significant pararneters. The accuracy of predicting the prognosis at 6 months was 82. 8%, when the classification functions were applied. Nlerefore the findings of early electrophysiological studies would be irnportant in understanding the serial pathophysiological changes and assessing the clinical outcorne of Guillain-Barre syndrorne
