The sit\u2010to\u2010stand (STS) movement is a fundamental daily activity, and biomechanical parameters derived from STS capture quantitative aspects of mobility. However, their association with LS severity remains unclear. We aimed to examine whether STS parameters are associated with LS severity in this cross\u2010sectional study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We analyzed 1047 adults (619 males, 428 females; median age 54\u2009years) who underwent musculoskeletal health screening. LS stage was classified into non\u2010LS, LS1, LS2, and LS3 using the stand\u2010up test, two\u2010step test, and the 25\u2010question Geriatric Locomotive Function Scale. STS performance was measured with the STS force analyzer, and three parameters were derived: maximum ground reaction force normalized to body weight (F\/w), rate of force development normalized to body weight (RFD\/w), and stabilization time (ST). Associations between LS stage and these parameters were assessed using ordinal logistic regression adjusted for age, sex, and body mass index.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among participants, 47.0% were non\u2010LS, 46.0% LS1, 5.8% LS2, and 1.1% LS3. Compared with non\u2010LS, both F\/w and RFD\/w were significantly lower in LS1 and LS2, while ST was significantly longer in LS1. In ordinal logistic regression analysis, only RFD\/w remained significantly associated with LS stage after adjustment (odds ratio: 0.84; 95% CI: 0.76\u20130.94;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.002).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our findings revealed that only lower RFD\/w was independently associated with LS severity, suggesting that RFD\/w could complement conventional LS risk tests.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/ggi.70314","type":"journal-article","created":{"date-parts":[[2026,1,5]],"date-time":"2026-01-05T10:24:01Z","timestamp":1767608641000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Rate of Force Development During Sit\u2010to\u2010Stand Movement Is Associated With Locomotive Syndrome Severity: A Cross\u2010Sectional Study"],"prefix":"10.1111","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-6352-5925","authenticated-orcid":false,"given":"Takashi","family":"Seya","sequence":"first","affiliation":[{"name":"Department of Orthopaedics Graduate School of Medical Science, Kyoto Prefectural University of Medicine Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9405-8462","authenticated-orcid":false,"given":"Naoki","family":"Okubo","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Graduate School of Medical Science, Kyoto Prefectural University of Medicine Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuji","family":"Nakagawa","sequence":"additional","affiliation":[{"name":"Department of Sports and Para\u2010Sports Medicine Graduate School of Medical Science, Kyoto Prefectural University of Medicine Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taisuke","family":"Kunitomo","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Kyoto Tanabe Central Hospital Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kanako","family":"Iinuma","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Graduate School of Medical Science, Kyoto Prefectural University of Medicine Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazufumi","family":"Hisamoto","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Graduate School of Medical Science, Kyoto Prefectural University of Medicine Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soshi","family":"Hirata","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Graduate School of Medical Science, Kyoto Prefectural University of Medicine Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Graduate School of Medical Science, Kyoto Prefectural University of Medicine Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,1,5]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.aat0497"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/14397595.2018.1452173"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12891-021-04539-4"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12018-016-9208-2"},{"key":"e_1_2_11_6_1","unstructured":"Council LC \u201cLocomotive syndrome.
