A comprehensive description of the electromyographic (EMG) findings in AMD is lacking. The purpose of this study is to describe the EMG features in adult\u2010onset AMD, focusing on the distribution of EM. <jats:italic>Methods<\/jats:italic>: A retrospective chart review of AMD patients diagnosed at Mayo Clinic over age 18 years. <jats:italic>Results<\/jats:italic>: Thirty\u2010seven patients were included. Twenty\u2010eight (76%) had EM in at least 1 muscle, and EM was more common in paraspinal and proximal limb muscles. The tensor fasciae latae (TFL) was equally sensitive to the paraspinals for EM. Three of 4 patients had EM identified in the diaphragm. <jats:italic>Conclusions<\/jats:italic>: Approximately three\u2010quarters of adult\u2010onset AMD patients display EM on EMG. The paraspinal muscles and TFL are the most likely to demonstrate EM, and EM can be detected in the diaphragm of adult onset AMD patients. <jats:italic>Muscle Nerve<\/jats:italic>, 2015 <jats:italic>Muscle Nerve<\/jats:italic> <jats:bold>51<\/jats:bold>:759\u2013761, 2015<\/jats:p><\/jats:sec>","DOI":"10.1002\/mus.24620","type":"journal-article","created":{"date-parts":[[2015,2,23]],"date-time":"2015-02-23T07:39:13Z","timestamp":1424677153000},"page":"759-761","source":"Crossref","is-referenced-by-count":32,"title":["Electromyographic findings in 37 patients with adult\u2010onset acid maltase deficiency"],"prefix":"10.1002","volume":"51","author":[{"given":"Charles D.","family":"Kassardjian","sequence":"first","affiliation":[{"name":"Department of Neurology Mayo Clinic 200 1<sup>st<\/sup> Street SW Rochester MN USA 55905"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew G.","family":"Engel","sequence":"additional","affiliation":[{"name":"Department of Neurology Mayo Clinic 200 1<sup>st<\/sup> Street SW Rochester MN USA 55905"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric J.","family":"Sorenson","sequence":"additional","affiliation":[{"name":"Department of Neurology Mayo Clinic 200 1<sup>st<\/sup> Street SW Rochester MN USA 55905"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,3,31]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.55.8.1122"},{"key":"e_1_2_6_3_1","first-page":"382","article-title":"Acid maltase deficiency: comparison of infantile, childhood, and adult types","volume":"20","author":"Engel AG","year":"1970","journal-title":"Neurology"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.880160614"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/CND.0b013e3181d7c323"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/93.3.599"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.20722"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.21615"},{"key":"e_1_2_6_9_1","first-page":"406","article-title":"Acid maltase deficiency: clinical and laboratory features of adult\u2010onset cases","volume":"114","author":"Read K","year":"2001","journal-title":"N Z Med J"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0000000000000163"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.23.1.95"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nmd.2007.06.002"}],"container-title":["Muscle &amp; Nerve"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fmus.24620","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mus.24620","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,4]],"date-time":"2023-10-04T05:56:45Z","timestamp":1696399005000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/mus.24620"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,3,31]]},"references-count":11,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2015,5]]}},"alternative-id":["10.1002\/mus.24620"],"URL":"https:\/\/doi.org\/10.1002\/mus.24620","archive":["Portico"],"relation":{},"ISSN":["0148-639X","1097-4598"],"issn-type":[{"value":"0148-639X","type":"print"},{"value":"1097-4598","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,3,31]]}}}
