The results show specific links between upper limb movements and manipulability, revealing that extreme poses show less manipulability, i.e., when the arms are fully extended or fully flexed. However, there is not a clear correlation between the sEMG signals\u2019 average activity and manipulability factors, which suggests that muscular activity is, at least, only indirectly related to human pose singularities. A possible means to infer these correlations, if any, would be the use of advanced deep learning techniques. We also analyze a set of EMG metrics that give insights into how muscular effort is distributed during the exercises. This set of metrics could be used to obtain good indicators for the quantitative evaluation of sequences of movements according to the milestones of a rehabilitation therapy or to plan more ergonomic and bearable movement phases in a working task.<\/jats:p>","DOI":"10.3390\/bios13070697","type":"journal-article","created":{"date-parts":[[2023,7,3]],"date-time":"2023-07-03T00:53:16Z","timestamp":1688345596000},"page":"697","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Multisensory Evaluation of Muscle Activity and Human Manipulability during Upper Limb Motor Tasks"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2676-117X","authenticated-orcid":false,"given":"Jose M.","family":"Lopez-Castellanos","sequence":"first","affiliation":[{"name":"Human Robotics Group, University of Alicante, 03690 San Vicente del Raspeig, Spain"},{"name":"Department of Systems Engineering, National Autonomous University of Honduras, Tegucigalpa 11101, Honduras"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8635-6061","authenticated-orcid":false,"given":"Jose L.","family":"Ramon","sequence":"additional","affiliation":[{"name":"Human Robotics Group, University of Alicante, 03690 San Vicente del Raspeig, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7523-9118","authenticated-orcid":false,"given":"Jorge","family":"Pomares","sequence":"additional","affiliation":[{"name":"Human Robotics Group, University of Alicante, 03690 San Vicente del Raspeig, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3919-9606","authenticated-orcid":false,"given":"Gabriel J.","family":"Garcia","sequence":"additional","affiliation":[{"name":"Human Robotics Group, University of Alicante, 03690 San Vicente del Raspeig, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3223-025X","authenticated-orcid":false,"given":"Andres","family":"Ubeda","sequence":"additional","affiliation":[{"name":"Human Robotics Group, University of Alicante, 03690 San Vicente del Raspeig, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"187","DOI":"10.1080\/1463922X.2014.930540","article-title":"Postural analysis and workspace design using an analytically derived inverse kinematics model","volume":"16","author":"Alvarez","year":"2015","journal-title":"Theor.
