Very early Guillain-Barré syndrome: A clinical-electrophysiological and ultrasonographic study

Using recent optimized electrodiagnostic criteria sets, we primarily aimed at verifying the accuracy of the initial electrophysiological test in very early Guillain-Barré syndrome (VEGBS), ≤4 days of onset, compared with the results of serial electrophysiology. Our secondary objective was to correlate early electrophysiological results with sonographic nerve changes. This is a retrospective study based on consecutive VEGBS patients admitted to...
