Furthermore, when performing two tasks at the same time, people with fibromyalgia showed a higher dual-task cost compared to a single task than healthy people. This may result in poorer performance of activities of daily living that are commonly presented as a combination of two or more tasks. Transcranial direct current stimulation (tDCS) is a promising nonpharmacological therapy. However, there is controversy regarding the intensities and the effectiveness of this therapy. Thus, the present study will aim: (1) to compare the effectiveness and the impact of two tDCS intensities (1 mA and 2 mA) on cognitive, motor, brain functions, and cardiac autonomic modulation; (2) to study the impact of tDCS on the dual-task performance and creativity after applying tDCS in dorsolateral prefrontal cortex. In this study, 26 women will participate and will be divided into two groups: women with fibromyalgia (n = 13), and healthy controls (n = 13). A reduction in cognitive-motor interference in dual-task performance is expected, as well as a modification in neurophysiological parameters and an improvement in cardiac autonomic modulation. Lastly, no different effects are expected depending on the stimulation intensity applied. The obtained results will help to determine if tDCS in the dorsolateral prefrontal cortex could improve the occupational performance of women with fibromyalgia.<\/jats:p>","DOI":"10.3390\/bs12020037","type":"journal-article","created":{"date-parts":[[2022,2,6]],"date-time":"2022-02-06T20:36:47Z","timestamp":1644179807000},"page":"37","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Effects of Transcranial Direct Current Stimulation on Brain Electrical Activity, Heart Rate Variability, and Dual-Task Performance in Healthy and Fibromyalgia Women: A Study Protocol"],"prefix":"10.3390","volume":"12","author":[{"given":"Mari Carmen","family":"Gomez-Alvaro","sequence":"first","affiliation":[{"name":"Physical Activity and Quality of Life Research Group (AFYCAV), 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":"Physical Activity and Quality of Life Research Group (AFYCAV), Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0757-5937","authenticated-orcid":false,"given":"Juan Luis","family":"Leon-Llamas","sequence":"additional","affiliation":[{"name":"Physical Activity and Quality of Life Research Group (AFYCAV), Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0410-6051","authenticated-orcid":false,"given":"Alvaro","family":"Murillo-Garcia","sequence":"additional","affiliation":[{"name":"Physical Activity and Quality of Life Research Group (AFYCAV), Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda","family":"Melo-Alonso","sequence":"additional","affiliation":[{"name":"Physical Activity and Quality of Life Research Group (AFYCAV), 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":"Physical Activity and Quality of Life Research Group (AFYCAV), Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pablo","family":"Molero","sequence":"additional","affiliation":[{"name":"Physical Activity and Quality of Life Research Group (AFYCAV), Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricardo","family":"Cano-Plasencia","sequence":"additional","affiliation":[{"name":"Clinical Neurophysiology, San Pedro de Alc\u00e1ntara Hospital, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1001-8883","authenticated-orcid":false,"given":"Narcis","family":"Gusi","sequence":"additional","affiliation":[{"name":"Physical Activity and Quality of Life Research Group (AFYCAV), Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"},{"name":"International Institute for Innovation in Aging, University of Extremadura, 10003 C\u00e1ceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,4]]},"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","doi-asserted-by":"crossref","first-page":"e25","DOI":"10.1183\/20734735.019717","article-title":"Cardiorespiratory fitness among adults with fibromyalgia","volume":"14","author":"Gaudreault","year":"2018","journal-title":"Breathe"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"293","DOI":"10.1016\/S1297-319X(02)00373-1","article-title":"Muscle performance in patients with fibromyalgia","volume":"69","author":"Maquet","year":"2002","journal-title":"Jt.
