Electrodiagnostic criteria for polyneuropathy and demyelination: application in 135 patients with Guillain-Barre syndrome. Dutch Guillain-Barre Study Group.

Since the development of effective but expensive therapeutic strategies for the treatment of Guillain-Barré syndrome, early confirmation of the diagnosis has become very important. Electrodiagnostic criteria were developed for the discrimination of polyneuropathy and in particular for demyelination. The sensitivity and specificity of these criteria were determined in 135 patients with Guillain-Barré syndrome in an early stage of the disease, along with 45 healthy volunteers. The algorithms used to develop our criteria consisted of sets of selected electrodiagnostic variables, each of them rele... Mehr ...
