They have a markedly longer disease duration before a diagnosis was made, which could also be the result of difficulty in eliciting motor root conduction block as a sign of proximal demyelination as observed in every patient. Pain is a universal feature as is sensory nerve conduction abnormality. None responded to immunotherapy, but disease stabilization was observed over the chronic course.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Although rare, these unique observations in Asian patients with LSS differ from those reported in Western literature. The presence of motor root conduction block demonstrated for the first time is instrumental in establishing a diagnosis.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1097\/cnd.0b013e31820d4f43","type":"journal-article","created":{"date-parts":[[2011,2,12]],"date-time":"2011-02-12T10:36:19Z","timestamp":1297506979000},"page":"158-162","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Motor Root Conduction Block in the Lewis-Sumner Syndrome"],"prefix":"10.1097","volume":"12","author":[{"given":"Yew Long","family":"Lo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang-Fang","family":"Dan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yam-Eng","family":"Tan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teng-Hee","family":"Leoh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-9-20240808","doi-asserted-by":"crossref","first-page":"2010","DOI":"10.1093\/brain\/awh222","article-title":"Follow-up study and response to treatment in 23 patients with Lewis-Sumner syndrome.","volume":"127","author":"Viala","year":"2004","journal-title":"Brain"},{"key":"R2-9-20240808","doi-asserted-by":"crossref","first-page":"582","DOI":"10.1016\/0013-4694(86)90145-8","article-title":"Electrical stimulation over the human vertebral column: which neural elements are excited?","volume":"63","author":"Mills","year":"1986","journal-title":"Electroencephalogr Clin Neurophysiol"},{"key":"R3-9-20240808","doi-asserted-by":"crossref","first-page":"770","DOI":"10.1136\/jnnp.53.9.770","article-title":"Magnetic and electrical stimulation of cervical motor roots: technique, site and mechanisms of excitation.","volume":"53","author":"Schmid","year":"1990","journal-title":"J Neurol Neurosurg Psychiatry"},{"key":"R4-9-20240808","doi-asserted-by":"crossref","first-page":"88","DOI":"10.1002\/mus.20236","article-title":"Lewis-Sumner syndrome and multifocal motor neuropathy.","volume":"31","author":"Verschueren","year":"2005","journal-title":"Muscle Nerve"},{"key":"R5-9-20240808","doi-asserted-by":"crossref","first-page":"586","DOI":"10.1136\/jnnp.66.5.586","article-title":"Motor root conduction block in neuralgic amyotrophy: evidence of proximal conduction block.","volume":"66","author":"Lo","year":"1999","journal-title":"J Neurol Neurosurg Psychiatry"},{"key":"R6-9-20240808","doi-asserted-by":"crossref","first-page":"559","DOI":"10.1002\/mus.1041","article-title":"Conduction block in neuralgic amyotrophy.","volume":"24","author":"Watson","year":"2001","journal-title":"Muscle Nerve"},{"key":"R7-9-20240808","doi-asserted-by":"crossref","first-page":"1303","DOI":"10.1002\/(SICI)1097-4598(199710)20:10<1303::AID-MUS13>3.0.CO;2-3","article-title":"Chronic relapsing brachial plexus neuropathy with persistent conduction block.","volume":"20","author":"Amato","year":"1997","journal-title":"Muscle Nerve"},{"key":"R8-9-20240808","doi-asserted-by":"crossref","first-page":"91","DOI":"10.1016\/j.jns.2004.08.009","article-title":"Motor root conduction block in traumatic brachial plexopathy.","volume":"227","author":"Lo","year":"2004","journal-title":"J Neurol Sci"},{"key":"R9-9-20240808","doi-asserted-by":"crossref","first-page":"530","DOI":"10.1212\/01.WNL.0000150582.80346.2C","article-title":"Radiculoplexopathy with conduction block caused by acute Epstein-Barr virus infection.","volume":"64","author":"Vucic","year":"2005","journal-title":"Neurology"},{"key":"R10-9-20240808","doi-asserted-by":"crossref","first-page":"1123","DOI":"10.4065\/72.12.1123","article-title":"Subacute diabetic proximal neuropathy.","volume":"72","author":"Pascoe","year":"1997","journal-title":"Mayo Clin Proc"}],"container-title":["Journal of Clinical Neuromuscular Disease"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/00131402-201103000-00009","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T18:54:36Z","timestamp":1786042476000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/00131402-201103000-00009"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,3]]},"references-count":10,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2011]]}},"URL":"https:\/\/doi.org\/10.1097\/cnd.0b013e31820d4f43","relation":{},"ISSN":["1522-0443"],"issn-type":[{"value":"1522-0443","type":"print"}],"subject":[],"published":{"date-parts":[[2011,3]]}}}
