Eight healthy subjects participated in the study. Electrode\u2013skin impedance was evaluated in the rectus abdominal muscle every five minutes, over a total period of 50 min. A reduction of 13.23% in the impedance values was observed in minute 10 (p = 0.007), and a reduction of 9.02% was observed in minute 15 (p = 0.029). No statistically significant differences were observed in the other instants evaluated. The findings obtained in the present study demonstrate a decrease in electrode\u2013skin impedance from minute 5 to minute 15, followed by a stabilization period with a low percentage of variation till minute 50.<\/jats:p>","DOI":"10.3390\/s23208582","type":"journal-article","created":{"date-parts":[[2023,10,19]],"date-time":"2023-10-19T07:15:36Z","timestamp":1697699736000},"page":"8582","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Long-Term Electrode\u2013Skin Impedance Variation for Electromyographic Measurements"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9528-1463","authenticated-orcid":false,"given":"Andreia","family":"Sousa","sequence":"first","affiliation":[{"name":"Center for Rehabilitation Research (CIR), ESS, Polytechnic of Porto, rua Dr. Ant\u00f3nio Bernardino de Almeida, 4200-072 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2590-962X","authenticated-orcid":false,"given":"Andreia","family":"Noites","sequence":"additional","affiliation":[{"name":"Center for Rehabilitation Research (CIR), ESS, Polytechnic of Porto, rua Dr. Ant\u00f3nio Bernardino de Almeida, 4200-072 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4422-8440","authenticated-orcid":false,"given":"Rui","family":"Vilarinho","sequence":"additional","affiliation":[{"name":"Center for Rehabilitation Research (CIR), ESS, Polytechnic of Porto, rua Dr. Ant\u00f3nio Bernardino de Almeida, 4200-072 Porto, Portugal"},{"name":"FP-I3ID, Escola Superior de Sa\u00fade-Fernando Pessoa, 4200-253 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7394-7604","authenticated-orcid":false,"given":"Rubim","family":"Santos","sequence":"additional","affiliation":[{"name":"Center for Rehabilitation Research (CIR), ESS, Polytechnic of Porto, rua Dr. Ant\u00f3nio Bernardino de Almeida, 4200-072 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"345","DOI":"10.1016\/j.neucli.2008.10.001","article-title":"Posture, dynamic stability, and voluntary movement","volume":"38","author":"Bouisset","year":"2008","journal-title":"Neurophysiol.
