However, it was unclear which parts of the upper- or lower-limb PhA were involved. This study investigated the differences in the PhA of the upper and lower extremities and their relationships with frailty, locomotive syndrome indices, and motor function in community-dwelling older adult participants. This study was a cross-sectional observational study. In 69 community-dwelling older adults, the PhA at each measurement site (whole body, upper limbs, and lower limbs), motor function, Kihon Checklist (KCL), and 25-Geriatric Locomotive Function Scale (GLFS-25) were measured. This study examined differences in each PhA and its relationship with motor function and geriatric diseases. Multiple regression analysis was performed using GLFS-25 as the dependent variable and sex and lower-limb PhA as independent variables. In this cohort (mean age: 72.3 \u00b1 5.7 years; 18 males and 51 females), lower-limb PhA was significantly lower than upper-limb PhA. Unlike other PhAs, lower-limb PhA was related to grip strength, TUG, F\/w, and GLFS-25. Multiple regression analysis showed that the lower-limb PhA was independently related to GLFS-25. Cellular health of the lower extremity is associated with gait, standing function, and indicators of locomotive syndrome.<\/jats:p>","DOI":"10.3390\/geriatrics8060121","type":"journal-article","created":{"date-parts":[[2023,12,14]],"date-time":"2023-12-14T03:58:02Z","timestamp":1702526282000},"page":"121","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Associations of Lower-Limb Phase Angle with Locomotion and Motor Function in Japanese Community-Dwelling Older Adults"],"prefix":"10.3390","volume":"8","author":[{"given":"Daisuke","family":"Homma","sequence":"first","affiliation":[{"name":"Division of Orthopaedic Surgery, Niigata University Graduate School of Medical and Dental Sciences, Niigata 951-8510, Japan"},{"name":"Department of Rehabilitation, Niigata Bandai Hospital, Niigata 950-0909, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Izumi","family":"Minato","sequence":"additional","affiliation":[{"name":"Division of Orthopaedic Surgery, Niigata Rinko Hospital, Niigata 950-0051, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2289-7499","authenticated-orcid":false,"given":"Norio","family":"Imai","sequence":"additional","affiliation":[{"name":"Division of Comprehensive Musculoskeletal Medicine, Niigata University Graduate School of Medical and Dental Sciences, Niigata 951-8510, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dai","family":"Miyasaka","sequence":"additional","affiliation":[{"name":"Division of Orthopaedic Surgery, Niigata Bandai Hospital, Niigata 950-0909, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoji","family":"Horigome","sequence":"additional","affiliation":[{"name":"Division of Comprehensive Musculoskeletal Medicine, Niigata University Graduate School of Medical and Dental Sciences, Niigata 951-8510, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hayato","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Division of Orthopaedic Surgery, Niigata University Graduate School of Medical and Dental Sciences, Niigata 951-8510, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoichiro","family":"Dohmae","sequence":"additional","affiliation":[{"name":"Division of Orthopaedic Surgery, Niigata Bandai Hospital, Niigata 950-0909, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoto","family":"Endo","sequence":"additional","affiliation":[{"name":"Division of Orthopaedic Surgery, Niigata Prefectural Tsubame Rosai Hospital, Tsubame, Niigata 959-1228, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"604","DOI":"10.46234\/ccdcw2021.160","article-title":"Major Trends in Population Growth Around the World","volume":"3","author":"Gu","year":"2021","journal-title":"China CDC Wkly."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"104220","DOI":"10.1016\/j.archger.2020.104220","article-title":"National Prevalence of Frailty in the Older Japanese Population: Findings from a Nationally Representative Survey","volume":"91","author":"Murayama","year":"2020","journal-title":"Arch.
