Published criteria for differentiation into GBS subtypes focus on cutoff values, but other items receive less attention, although they may influence EDx subtyping: (a) extensiveness of EDx testing, (b) nerve\u2010specific considerations, (c) distal compound muscle action potential (CMAP)\u2010amplitude requirements, (d) criteria for conduction block and temporal dispersion. The aims of this study were to investigate how these aspects were approached by neuromuscular EDx experts in practice and how this was done in previously published EDx criteria for GBS. A completed questionnaire was returned by 24 (of 49) members of the electrophysiology expertise group from the International GBS Outcome Study. Six published EDx criteria for GBS subtyping were compared regarding these aspects. The indicated minimal number of motor nerves to study varied among respondents and tended to be more extensive in equivocal than normal studies. Respondents varied considerably regarding usage of compression sites for subtyping (median\/wrist, ulnar\/elbow, peroneal\/fibular head): 29% used all variables from all sites, 13% excluded all sites, and 58% used only some sites and\/or variables. Thirty\u2010eight percent of respondents required a minimal distal CMAP amplitude to classify distal motor latency as demyelinating, and 58% did for motor conduction velocity. For proximal\/distal CMAP\u2010amplitude ratio and F\u2010wave latency, a requisite minimal CMAP amplitude was more often required (79%). Also, the various published criteria sets showed differences on all items. Practical use of EDx criteria for subtyping GBS vary extensively across respondents, potentially lowering the reproducibility of GBS subtyping.<\/jats:p>","DOI":"10.1111\/jns.12504","type":"journal-article","created":{"date-parts":[[2022,6,14]],"date-time":"2022-06-14T19:09:15Z","timestamp":1655233755000},"page":"197-205","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Electrodiagnostic subtyping in <scp>Guillain\u2010Barr\u00e9<\/scp> syndrome: Use of criteria in practice based on a survey study in <scp>IGOS<\/scp>"],"prefix":"10.1111","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4279-4657","authenticated-orcid":false,"given":"Samuel","family":"Arends","sequence":"first","affiliation":[{"name":"Department of Neurology Erasmus University Medical Center  Rotterdam The Netherlands"},{"name":"Department of Neurology Haga Teaching Hospital The Hague  The Hague The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2165-6573","authenticated-orcid":false,"given":"Judith","family":"Drenthen","sequence":"additional","affiliation":[{"name":"Department of Neurology Erasmus University Medical Center  Rotterdam The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1954-4617","authenticated-orcid":false,"given":"Peter Y.K","family":"Van den Bergh","sequence":"additional","affiliation":[{"name":"Department of Neurology University Hospital St\u2010Luc  Brussels Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9702-0256","authenticated-orcid":false,"given":"Robert D.M.","family":"Hadden","sequence":"additional","affiliation":[{"name":"Department of Neurology King's College Hospital  London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nortina","family":"Shahrizaila","sequence":"additional","affiliation":[{"name":"Department of Neurology University of Malaya  Kuala Lumpur Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mazen M.","family":"Dimachkie","sequence":"additional","affiliation":[{"name":"Department of Neurology The University of Kansas Medical Center  Kansas City Kansas USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerardo","family":"Guti\u00e9rrez Guti\u00e9rrez","sequence":"additional","affiliation":[{"name":"Department of Neurology Hospital Universitario Infanta Sofia  San Sebastian Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hans","family":"Katzberg","sequence":"additional","affiliation":[{"name":"Department of Neurology, Toronto General Hospital University Health Network  Toronto Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lynette","family":"Kiers","sequence":"additional","affiliation":[{"name":"Clinical Neurophysiology, Department of Neurology The Royal Melbourne Hospital  Parkville Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6205-2293","authenticated-orcid":false,"given":"Helmar C.","family":"Lehmann","sequence":"additional","affiliation":[{"name":"Department of Neurology University Hospital of Cologne  Cologne Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yann","family":"P\u00e9r\u00e9on","sequence":"additional","affiliation":[{"name":"Department of Clinical Neurophysiology, Reference Centre for Neuromuscular Disorders AOC, Filnemus, Euro\u2010NMD University of Nantes  Nantes France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ricardo C.","family":"Reisin","sequence":"additional","affiliation":[{"name":"Department of Neurology Hospital Brit\u00e1nico  Buenos Aires Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonino","family":"Uncini","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, Imaging and Clinical Sciences University \u201cG.
