Motor conduction studies in Miller Fisher syndrome with severe tetraparesis

Some patients with Miller Fisher syndrome (MFS) have a severe tetraparesis such as that observed in Guillain--Barré syndrome (GBS). To determine whether pathophysiologic differences exist between the tetraparesis in MFS and that in GBS, we compared clinical and motor conduction findings in 4 MFS patients who developed severe tetraparesis with those in 5 MFS patients without tetraparesis, and 14 GBS patients. MFS patients with or without...
