Usually, subjective measures or muscle activity are used for a cumulative evaluation; however, Industry 4.0 wearables allow overcoming the challenges observed in those methods. Thus, the aim of this study is to analyze alterations in respiratory inductance plethysmography (RIP) to measure the asynchrony between thorax and abdomen walls during repetitive work and its relationship with local fatigue. A total of 22 healthy participants (age: 27.0 \u00b1 8.3 yrs; height: 1.72 \u00b1 0.09 m; mass: 63.4 \u00b1 12.9 kg) were recruited to perform a task that includes grabbing, moving, and placing a box in an upper and lower shelf. This task was repeated for 10 min in three trials with a fatigue protocol between them. Significant main effects were found from Baseline trial to the Fatigue trials (p &lt; 0.001) for both RIP correlation and phase synchrony. Similar results were found for the activation amplitude of agonist muscle (p &lt; 0.001), and to the muscle acting mainly as a joint stabilizer (p &lt; 0.001). The latter showed a significant effect in predicting both RIP correlation and phase synchronization. Both RIP correlation and phase synchronization can be used for an overall fatigue assessment during repetitive work.<\/jats:p>","DOI":"10.3390\/s22114247","type":"journal-article","created":{"date-parts":[[2022,6,3]],"date-time":"2022-06-03T08:01:18Z","timestamp":1654243278000},"page":"4247","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Respiratory Inductance Plethysmography to Assess Fatigability during Repetitive Work"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9811-0571","authenticated-orcid":false,"given":"Lu\u00eds","family":"Silva","sequence":"first","affiliation":[{"name":"Laborat\u00f3rio de Instrumenta\u00e7\u00e3o, Engenharia Biom\u00e9dica e F\u00edsica da Radia\u00e7\u00e3o (LIBPhys-UNL), Departamento de F\u00edsica, Faculdade de Ci\u00eancias e Tecnologia, Universidade Nova de Lisboa, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0172-4559","authenticated-orcid":false,"given":"Mariana","family":"Dias","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Instrumenta\u00e7\u00e3o, Engenharia Biom\u00e9dica e F\u00edsica da Radia\u00e7\u00e3o (LIBPhys-UNL), Departamento de F\u00edsica, Faculdade de Ci\u00eancias e Tecnologia, Universidade Nova de Lisboa, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8481-6079","authenticated-orcid":false,"given":"Duarte","family":"Folgado","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Instrumenta\u00e7\u00e3o, Engenharia Biom\u00e9dica e F\u00edsica da Radia\u00e7\u00e3o (LIBPhys-UNL), Departamento de F\u00edsica, Faculdade de Ci\u00eancias e Tecnologia, Universidade Nova de Lisboa, 2829-516 Caparica, Portugal"},{"name":"Associa\u00e7\u00e3o Fraunhofer Portugal Research, Rua Alfredo Allen 455\/461, 4200-135 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1109-7189","authenticated-orcid":false,"given":"Maria","family":"Nunes","sequence":"additional","affiliation":[{"name":"Associa\u00e7\u00e3o Fraunhofer Portugal Research, Rua Alfredo Allen 455\/461, 4200-135 Porto, Portugal"}]},{"given":"Praneeth","family":"Namburi","sequence":"additional","affiliation":[{"name":"Institute for Medical Engineering and Science, Massachusetts Institute of Technology, Cambridge, MA 02139, USA"},{"name":"MIT.nano Immersion Lab, Massachusetts Institute of Technology, Cambridge, MA 02139, USA"}]},{"given":"Brian","family":"Anthony","sequence":"additional","affiliation":[{"name":"Institute for Medical Engineering and Science, Massachusetts Institute of Technology, Cambridge, MA 02139, USA"},{"name":"Device Realization Laboratory, Department of Mechanical Engineering, Massachusetts Institute of Technology, Cambridge, MA 02139, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4618-2474","authenticated-orcid":false,"given":"Diogo","family":"Carvalho","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, R\u012bga Stradi\u0146\u0161 University, 16 Dzirciema iela, LV-1007 R\u012bga, Latvia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8010-6478","authenticated-orcid":false,"given":"Miguel","family":"Carvalho","sequence":"additional","affiliation":[{"name":"Campus de Azur\u00e9m, Minho University, 4800-058 Guimar\u00e3es, Portugal"}]},{"given":"Elazer","family":"Edelman","sequence":"additional","affiliation":[{"name":"Institute for Medical Engineering and Science, Massachusetts Institute of Technology, Cambridge, MA 02139, USA"},{"name":"Brigham and Women\u2019s Hospital, Cardiovascular Division, 75 Francis Street, Boston, MA 02115, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4022-7424","authenticated-orcid":false,"given":"Hugo","family":"Gamboa","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Instrumenta\u00e7\u00e3o, Engenharia Biom\u00e9dica e F\u00edsica da Radia\u00e7\u00e3o (LIBPhys-UNL), Departamento de F\u00edsica, Faculdade de Ci\u00eancias e Tecnologia, Universidade Nova de Lisboa, 2829-516 Caparica, Portugal"},{"name":"Associa\u00e7\u00e3o Fraunhofer Portugal Research, Rua Alfredo Allen 455\/461, 4200-135 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"103142","DOI":"10.1016\/j.apergo.2020.103142","article-title":"Joint moment trade-offs across the upper extremity and trunk during repetitive work","volume":"88","author":"Mulla","year":"2020","journal-title":"Appl.
