Adults post-TTA, however, demonstrate reduced physical activity, predisposing them to adverse health outcomes. Identifying adults at the risk of sedentarism post-TTA via commonly used, objective clinical measures may enhance clinical decisions, including prosthesis prescription. The study\u2019s purpose was to determine whether residual and sound limb hip strength distinguishes between sedentary and nonsedentary adults post-TTA. A secondary analysis of a cross-sectional dataset (<jats:italic toggle=\"yes\">n<\/jats:italic>\u2009=\u200944) was conducted. Participant residual and sound limb hip flexion, extension, abduction and adduction strength were assessed via handheld dynamometry. Physical activity was monitored for 7 days and participants were classified as sedentary (&lt;5000 steps\/day; <jats:italic toggle=\"yes\">n<\/jats:italic>\u2009=\u200913) or nonsedentary (\u22655000 steps\/day; <jats:italic toggle=\"yes\">n<\/jats:italic>\u2009=\u200931). Receiver operating curves revealed that residual and sound limb hip extension, abduction and adduction strength distinguished between sedentary and nonsedentary adults post-TTA (<jats:italic toggle=\"yes\">P<\/jats:italic>\u2009&lt;\u20090.050). Preliminary cut-points for hip strength measures to classify adults at the risk of sedentarism were determined. A hip strength composite score (0\u20136) estimates a 2.2\u00d7 increased odds of being sedentary with each additional hip strength deficit. Post-TTA, residual and sound limb hip strength can help identify adults at risk of sedentarism to aid clinical decision making, including prosthesis prescription.<\/jats:p>","DOI":"10.1097\/mrr.0000000000000520","type":"journal-article","created":{"date-parts":[[2022,2,8]],"date-time":"2022-02-08T08:02:59Z","timestamp":1644307379000},"page":"137-145","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":4,"title":["Residual and sound limb hip strength distinguish between sedentary and nonsedentary adults with transtibial amputation"],"prefix":"10.1097","volume":"45","author":[{"given":"Mayank","family":"Seth","sequence":"first","affiliation":[{"name":"Department of Physical Therapy, Delaware Limb Loss Studies, University of Delaware, Newark DE, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryan T","family":"Pohlig","sequence":"additional","affiliation":[{"name":"Biostatistics Core, University of Delaware, Newark, DE, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emma H","family":"Beisheim-Ryan","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Delaware Limb Loss Studies, University of Delaware, Newark DE, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samantha J","family":"Stauffer","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Delaware Limb Loss Studies, University of Delaware, Newark DE, USA"},{"name":"Independence Prosthetics-Orthotics, Inc., Newark, DE, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John R","family":"Horne","sequence":"additional","affiliation":[{"name":"Independence Prosthetics-Orthotics, Inc., Newark, DE, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregory E","family":"Hicks","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Delaware Spine Studies, University of Delaware, Newark DE, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaclyn Megan","family":"Sions","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Delaware Limb Loss Studies, University of Delaware, Newark DE, USA"},{"name":"Department of Physical Therapy, Delaware Spine Studies, University of Delaware, Newark DE, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","published-online":{"date-parts":[[2022,2,7]]},"reference":[{"key":"R1-20250525","doi-asserted-by":"crossref","first-page":"721","DOI":"10.2165\/11590420-000000000-00000","article-title":"Amputees and sports: a systematic review.","volume":"41","author":"Bragaru","year":"2011","journal-title":"Sports Med"},{"key":"R2-20250525","doi-asserted-by":"crossref","first-page":"186","DOI":"10.1080\/03093640802016514","article-title":"Physical activity and quality of life: a study of a lower-limb amputee population.","volume":"32","author":"Deans","year":"2008","journal-title":"Prosthet Orthot Int"},{"key":"R3-20250525","doi-asserted-by":"crossref","first-page":"1063","DOI":"10.1080\/09638288.2017.1422031","article-title":"Physical activity participation amongst individuals with lower limb amputation.","volume":"41","author":"Langford","year":"2019","journal-title":"Disabil Rehabil"},{"key":"R4-20250525","doi-asserted-by":"crossref","first-page":"895","DOI":"10.1682\/JRRD.2013.06.0152","article-title":"Physical activity barriers and enablers in older Veterans with lower-limb amputation.","volume":"51","author":"Littman","year":"2014","journal-title":"J Rehabil Res Dev"},{"key":"R5-20250525","doi-asserted-by":"crossref","first-page":"280","DOI":"10.1016\/j.ypmed.2009.05.002","article-title":"Physical activity: health outcomes and importance for public health policy.","volume":"49","author":"Haskell","year":"2009","journal-title":"Prev Med"},{"key":"R6-20250525","doi-asserted-by":"crossref","first-page":"801","DOI":"10.1503\/cmaj.051351","article-title":"Health benefits of physical activity: the evidence.","volume":"174","author":"Warburton","year":"2006","journal-title":"CMAJ"},{"key":"R7-20250525","doi-asserted-by":"crossref","first-page":"422","DOI":"10.1016\/j.apmr.2007.11.005","article-title":"Estimating the prevalence of limb loss in the United States: 2005 to 2050.","volume":"89","author":"Ziegler-Graham","year":"2008","journal-title":"Arch Phys Med Rehabil"},{"key":"R8-20250525","doi-asserted-by":"crossref","first-page":"1","DOI":"10.2165\/00007256-200434010-00001","article-title":"How many steps\/day are enough?
