Sensory evoked potentials in Guillain-Barré polyneuropathy.
In 11 patients with acute Guillain-Barré polyneuropathy examined within 2 weeks of the onset of the paralysis, sensory evoked potential techniques were able to demonstrate a proximal conduction delay between Erb's point and the cervical cord in 10 subjects; while sensory conduction distal to Erb's point was much more commonly normal in the early period. Sensory evoked potential techniques provide therefore a valuable way to demonstrate proximal conduction velocity slowing early in the course of this disease.
