Workers with disabilities are likely to require additional support from another person to assemble or use these devices.

We utilized a noninvasive wearable FMG sensor to capture the radial force exerted by muscles during contractions, and we evaluated the effectiveness of FMG in assessing varying perceived exertion levels. We found a strong correlation between FMG measurements and perceived exertion, which highlights its potential as an indicator of physical effort. Integrating FMG sensors could allow for monitoring of worker exertion, facilitating adjustments to workloads and the design of ergonomic tools and interfaces. Doing so could help identify risks of fatigue and musculoskeletal disorders and provide a valuable metric for refining job design and ergonomics assessments, ultimately contributing to healthier workplaces and enhanced worker productivity.</p>","PeriodicalId":73332,"journal":{"name":"IISE transactions on occupational ergonomics and human factors","volume":" ","pages":"54-63"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144058016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
