A total of 37 women with fibromyalgia participated in the study. Participants completed the 30 s arm curl test and 30 s chair stand test in both simple and dual-task conditions. These tests were repeated after seven days. In the 30 s chair stand dual-task test the reliability was low to good whereas that of the total performance variable was low to moderate. The reliability in both the 30 s arm curl dual-task test and the total performance variable were good to moderate. Both the 30 s chair stand test and 30 s arm curl test under dual-task conditions and the total performance variables had good test\u2013retest reliability. However, it is necessary to consider the fluctuations of the intraclass correlation coefficient (ICC).<\/jats:p>","DOI":"10.3390\/ijerph16244971","type":"journal-article","created":{"date-parts":[[2019,12,6]],"date-time":"2019-12-06T10:41:44Z","timestamp":1575628904000},"page":"4971","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Strength Assessment Under Dual Task Conditions in Women with Fibromyalgia: A Test\u2013Retest Reliability Study"],"prefix":"10.3390","volume":"16","author":[{"given":"Juan Luis","family":"Leon-Llamas","sequence":"first","affiliation":[{"name":"Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0784-1753","authenticated-orcid":false,"given":"Santos","family":"Villafaina","sequence":"additional","affiliation":[{"name":"Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alvaro","family":"Murillo-Garcia","sequence":"additional","affiliation":[{"name":"Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5140-465X","authenticated-orcid":false,"given":"Daniel","family":"Collado-Mateo","sequence":"additional","affiliation":[{"name":"Centre for Sport Studies, Rey Juan Carlos University, 28943 Fuenlabrada, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francisco Javier","family":"Dom\u00ednguez-Mu\u00f1oz","sequence":"additional","affiliation":[{"name":"Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jes\u00fas","family":"S\u00e1nchez-G\u00f3mez","sequence":"additional","affiliation":[{"name":"Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Narcis","family":"Gusi","sequence":"additional","affiliation":[{"name":"Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"600","DOI":"10.1002\/acr.20140","article-title":"The American College of Rheumatology preliminary diagnostic criteria for fibromyalgia and measurement of symptom severity","volume":"62","author":"Wolfe","year":"2010","journal-title":"Arthritis Care Res."},{"key":"ref_2","first-page":"519","article-title":"Prevalence and impact of fibromyalgia on function and quality of life in individuals from the general population: Results from a nationwide study in Spain","volume":"26","author":"Mas","year":"2008","journal-title":"Clin.
