Distal limb muscles showed more frequent EMG abnormalities than proximal muscles. EDX yield was found to be higher in the limb where weakness began and when clinical signs of LMN dysfunction were evident. Adoption of the Awaji criteria significantly increased the yield of EMG\u2010positive segments in the cervical (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.0005) and lumbosacral (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.0001) regions, and upgraded 19 patients into the probable category and 1 patient into the definite category. <jats:italic>Discussion<\/jats:italic>: EMG abnormalities are predominant in the distal limb in early\u2010stage ALS. A redefinition of an EDX\u2010positive cervical or lumbosacral segment, with an emphasis on distal limb muscles, may result in an earlier ALS diagnosis. <jats:italic>Muscle Nerve<\/jats:italic> <jats:bold>58<\/jats:bold>: 389\u2013395, 2018<\/jats:p>","DOI":"10.1002\/mus.26158","type":"journal-article","created":{"date-parts":[[2018,5,9]],"date-time":"2018-05-09T23:50:33Z","timestamp":1525909833000},"page":"389-395","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Distal Predominance of Electrodiagnostic Abnormalities in Early\u2010Stage Amyotrophic Lateral Sclerosis"],"prefix":"10.1002","volume":"58","author":[{"given":"Luay","family":"Shayya","sequence":"first","affiliation":[{"name":"Neuromuscular Center, Department of Neurology Cleveland Clinic Foundation 9500 Euclid Avenue, Cleveland Ohio 44195 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suma","family":"Babu","sequence":"additional","affiliation":[{"name":"Department of Neurology, Neurological Clinical Research Institute, Harvard Medical School Massachusetts General Hospital Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erik P.","family":"Pioro","sequence":"additional","affiliation":[{"name":"Neuromuscular Center, Department of Neurology Cleveland Clinic Foundation 9500 Euclid Avenue, Cleveland Ohio 44195 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianbo","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Quantitative Health Sciences, Lerner Research Institute Cleveland Clinic Foundation Cleveland Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuebing","family":"Li","sequence":"additional","affiliation":[{"name":"Neuromuscular Center, Department of Neurology Cleveland Clinic Foundation 9500 Euclid Avenue, Cleveland Ohio 44195 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,8,23]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/146608200300079536"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2007.09.143"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.25444"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.880171115"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.10356"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000260965.20021.47"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pmr.2012.08.022"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.20-07-02534.2000"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00401-017-1708-8"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nbd.2007.07.003"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.57.8.1171"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.25662"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.2009.197434"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/ana.22380"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.3109\/21678421.2014.887118"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0000000000002988"}],"container-title":["Muscle &amp;
