The sural-sparing pattern in clinical variants and electrophysiological subtypes of Guillain-Barré syndrome.

Background:  Guillain-Barré syndrome (GBS) is the most common cause of acute flaccid paralysis worldwide and can be classified into electrophysiological subtypes and clinical variants.

Objective:  This study aimed to compare the frequency of the sural-sparing pattern (SSP) in subtypes and variants of GBS.

Methods:  This retrospective cohort study analyzed clinical and electrophysiological data of 171 patients with GBS hospitalized in public and private hospitals of Natal, Rio Grande do Norte, Brazil, between 1994 and 2018; all cases were followed up by the same neurologist in a reference neurology center.
