Since lower extremity dysfunction does not explain all mechanisms that contribute to mobility limitation, more holistic hypotheses that explain reduced mobility in older populations are needed. The shoulders facilitate dynamic stability for ambulation, but the impact of shoulder dysfunction on mobility is poorly understood. This study examined the cross-sectional association of restricted shoulder elevation and external rotation range of motion (ROM) with poor lower extremity function and walking endurance capacity among 613 older adults aged 60\u2009years and older in the Baltimore Longitudinal Study of Aging. Results showed that persons with abnormal shoulder elevation or external rotation ROM were 2.5 to 4.5 times more likely to perform poorly on the expanded Short Physical Performance Battery ( p\u2009&lt;\u2009.050) and the fast-paced 400\u2009m walk test ( p\u2009&lt;\u2009.050), relative to participants with normal shoulder ROM. These findings provide nascent preliminary evidence that shoulder dysfunction is associated with mobility limitation and suggest that future studies are needed to clarify its impact on mobility and to develop novel interventions to improve prevention or mitigation of age-related declines in mobility.<\/jats:p>","DOI":"10.1177\/23337214231179843","type":"journal-article","created":{"date-parts":[[2023,6,7]],"date-time":"2023-06-07T01:35:23Z","timestamp":1686101723000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Association of Shoulder Dysfunction with Mobility Limitation Among Older Adults in the Baltimore Longitudinal Study of Aging"],"prefix":"10.1177","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7315-1825","authenticated-orcid":false,"given":"Derik L.","family":"Davis","sequence":"first","affiliation":[{"name":"University of Maryland School of Medicine, Baltimore, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Sun","sequence":"additional","affiliation":[{"name":"University of Maryland School of Medicine, Baltimore, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eleanor M.","family":"Simonsick","sequence":"additional","affiliation":[{"name":"Intramural Research Program, National Institute on Aging, Baltimore, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,6,6]]},"reference":[{"key":"bibr1-23337214231179843","unstructured":"Baltimore Longitudinal Study of Aging (BLSA).
