Changes in MUNIX values due to E1 electrode position, number of surface electromyography interference pattern (SIP) epochs, SIP epoch duration, force of contraction, and outlier data points were investigated.\n Results:<\/jats:italic>\n MUNIX depends on optimized compound muscle action potential (CMAP) amplitude. Individual muscles showed variations when the number of epochs was low or when the SIP duration was short. Longer SIP duration allowed better recognition of artifacts. MUNIX results were affected by SIP values at all force levels but was more affected when SIP area was low.\n Discussion:<\/jats:italic>\n We recommend changing the E1 electrode position to maximize CMAP amplitude. Twenty or more SIP signals of 500\u2010ms duration should be recorded by using force levels ranging from slight to maximum. Traces should be reviewed to identify and exclude signals with tremor or solitary spikes.\n Muscle Nerve<\/jats:italic>\n 58<\/jats:bold>\n : 374\u2013380, 2018\n <\/jats:p>","DOI":"10.1002\/mus.26099","type":"journal-article","created":{"date-parts":[[2018,2,10]],"date-time":"2018-02-10T16:02:38Z","timestamp":1518278558000},"page":"374-380","source":"Crossref","is-referenced-by-count":59,"title":["Motor unit number index: Guidelines for recording signals and their analysis"],"prefix":"10.1002","volume":"58","author":[{"given":"Sanjeev D.","family":"Nandedkar","sequence":"first","affiliation":[{"name":"Natus Medical Incorporated, Hopewell Junction New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul E.","family":"Barkhaus","sequence":"additional","affiliation":[{"name":"Medical College of Wisconsin Milwaukee Wisconsin USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erik V.","family":"St\u00e5lberg","sequence":"additional","affiliation":[{"name":"University Hospital Uppsala Sweden"},{"name":"Institute of Neurosciences Uppsala Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph","family":"Neuwirth","sequence":"additional","affiliation":[{"name":"Kantonsspital St Gallen St Gallen Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus","family":"Weber","sequence":"additional","affiliation":[{"name":"Kantonsspital St Gallen St Gallen Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,3,3]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/TBME.2004.834281"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.21824"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.21707"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2012.01.004"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.24292"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2015.12.002"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2015.12.023"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.21878"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1080\/146608200300079536"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-510X(99)00210-5"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2011.02.017"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.medengphy.2015.11.002"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004691-199505010-00004"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.20798"},{"issue":"4","key":"e_1_2_7_16_1","first-page":"235","article-title":"Influence of the surface EMG electrode on the compound muscle action potential","volume":"46","author":"Barkhaus PE","year":"2006","journal-title":"Electromyogr Clin Neurophysiol"},{"key":"e_1_2_7_17_1","volume-title":"Single fiber EMG","author":"Stalberg E","year":"2011"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0153948"}],"container-title":["Muscle & Nerve"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fmus.26099","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mus.26099","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,16]],"date-time":"2023-09-16T02:43:19Z","timestamp":1694832199000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/mus.26099"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,3,3]]},"references-count":17,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2018,9]]}},"alternative-id":["10.1002\/mus.26099"],"URL":"https:\/\/doi.org\/10.1002\/mus.26099","archive":["Portico"],"relation":{},"ISSN":["0148-639X","1097-4598"],"issn-type":[{"value":"0148-639X","type":"print"},{"value":"1097-4598","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,3,3]]}}}
