The purpose of this study was to evaluate the efficiency of surface electromyography in describing the effects of the rapid palatal expansion (RPE) on Masseter (M) and Temporalis Anterior (T) muscles\u2019 activity in 53 children with different types of malocclusion: bilateral posterior crossbite (BPcb), underdeveloped maxillary complex without crossbite (NOcb) and unilateral posterior crossbite on the right (UPCBr) and on the left (UPCBl). The muscular activities during chewing tasks were assessed bilaterally before and after RPE application and three months after removal. Both the envelope\u2019s peak (\u00b5V) and its occurrence (% of chewing task) were extracted from the surface electromyography signal. Our results showed the presence of statistically significant differences (p &lt; 0.05) on temporomandibular joint muscles, across different assessments, in all the tested populations of subjects. Surface electromyography demonstrated a relationship between the correction of a maxillary transverse discrepancy and the restoration of a muscle\u2019s activation patterns comparable to healthy subjects for both T and M.<\/jats:p>","DOI":"10.3390\/s20072086","type":"journal-article","created":{"date-parts":[[2020,4,8]],"date-time":"2020-04-08T05:59:47Z","timestamp":1586325587000},"page":"2086","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Effects of Rapid Palatal Expansion on Chewing Biomechanics in Children with Malocclusion: A Surface Electromyography Study"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4723-0546","authenticated-orcid":false,"given":"Fabiola","family":"Spolaor","sequence":"first","affiliation":[{"name":"Department of Information Engineering, University of Padova, Via Gradenigo, 6-35121 Padua, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martina","family":"Mason","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, School of Dentistry, University of Padua, Via Giustiniani, 2-35128 Padua, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9087-3953","authenticated-orcid":false,"given":"Alberto","family":"De Stefani","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, School of Dentistry, University of Padua, Via Giustiniani, 2-35128 Padua, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2900-7196","authenticated-orcid":false,"given":"Giovanni","family":"Bruno","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, School of Dentistry, University of Padua, Via Giustiniani, 2-35128 Padua, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ottavia","family":"Surace","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, University of Padova, Via Gradenigo, 6-35121 Padua, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annamaria","family":"Guiotto","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, University of Padova, Via Gradenigo, 6-35121 Padua, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Gracco","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, School of Dentistry, University of Padua, Via Giustiniani, 2-35128 Padua, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2624-5415","authenticated-orcid":false,"given":"Zimi","family":"Sawacha","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, University of Padova, Via Gradenigo, 6-35121 Padua, Italy"},{"name":"Department of Medicine, University of Padova, Via Giustiniani, 2-35128 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"50","DOI":"10.4103\/2278-0203.115085","article-title":"Prevalence of malocclusion in urban libyan preschool children","volume":"2","author":"Bugaighis","year":"2013","journal-title":"J.
