There are several exosuits available for industrial work, which might be adapted to the needs of older persons to support STS transfers. However, objective measures to quantify and evaluate such systems are needed. The aim of this study was to quantify the possible support of an exosuit during the STS transfer of geriatric patients. Twenty-one geriatric patients with a median age of 82 years (1.\u20133.Q. 79\u201384 years) stood up at a normal pace (1) from a chair without using armrests, (2) with using armrests and (3) from a bed with pushing off, each condition with and without wearing an exosuit. Peak angular velocity of the thighs was measured by body-worn sensors. It was higher when standing up with exosuit support from a bed (92.6 (1.\u20133.Q. 84.3\u2013116.2)\u00b0\/s versus 79.7 (1.\u20133.Q. 74.6\u201398.2)\u00b0\/s; p = 0.014) and from a chair with armrests (92.9 (1.\u20133.Q. 78.3\u2013113.0)\u00b0\/s versus 77.8 (1.\u20133.Q. 59.3\u2013100.7)\u00b0\/s; p = 0.089) compared to no support. There was no effect of the exosuit when standing up from a chair without using armrests. In general, it was possible to quantify the support of the exosuit using sensor-measured peak angular velocity. These results suggest that depending on the STS condition, an exosuit can support older persons during the STS transfer.<\/jats:p>","DOI":"10.3390\/s23021032","type":"journal-article","created":{"date-parts":[[2023,1,16]],"date-time":"2023-01-16T04:57:19Z","timestamp":1673845039000},"page":"1032","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Effect of a Passive Exosuit on Sit-to-Stand Performance in Geriatric Patients Measured by Body-Worn Sensors\u2014A Pilot Study"],"prefix":"10.3390","volume":"23","author":[{"given":"Ulrich","family":"Lindemann","sequence":"first","affiliation":[{"name":"Department of Clinical Gerontology, Robert-Bosch-Hospital, 70376 Stuttgart, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jana","family":"Krespach","sequence":"additional","affiliation":[{"name":"Department of Clinical Gerontology, Robert-Bosch-Hospital, 70376 Stuttgart, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Urban","family":"Daub","sequence":"additional","affiliation":[{"name":"Biomechatronic Systems, Fraunhofer Institute for Manufacturing Engineering and Automation IPA, 70569 Stuttgart, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc","family":"Schneider","sequence":"additional","affiliation":[{"name":"Department of Clinical Gerontology, Robert-Bosch-Hospital, 70376 Stuttgart, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9972-904X","authenticated-orcid":false,"given":"Kim S.","family":"Sczuka","sequence":"additional","affiliation":[{"name":"Department of Clinical Gerontology, Robert-Bosch-Hospital, 70376 Stuttgart, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5987-447X","authenticated-orcid":false,"given":"Jochen","family":"Klenk","sequence":"additional","affiliation":[{"name":"Department of Clinical Gerontology, Robert-Bosch-Hospital, 70376 Stuttgart, Germany"},{"name":"Institute of Epidemiology and Medical Biometry, Ulm University, 89081 Ulm, Germany"},{"name":"Study Center Stuttgart, IB University of Health and Social Sciences, 70178 Stuttgart, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"304","DOI":"10.1093\/rheumatology\/23.4.304","article-title":"Designing chairs for the disabled arthritic","volume":"23","author":"Chamberlain","year":"1984","journal-title":"Br.
