The Tai Chi group exhibited a significantly greater reduction in initial double stance time during stair descent compared with the balance and posture control training group under both single\u2010task (<jats:italic>F<\/jats:italic>\u00a0=\u00a08.177, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.006, <jats:italic>\u03b7<\/jats:italic><jats:sup>2<\/jats:sup>\u00a0=\u00a00.143) and dual\u2010task (<jats:italic>F<\/jats:italic>\u00a0=\u00a05.007, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.03, <jats:italic>\u03b7<\/jats:italic><jats:sup>2<\/jats:sup>\u00a0=\u00a00.093) conditions. Meanwhile, the balance and posture control training group showed significant reductions in the dual\u2010task cost values of cadence (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.003) and speed (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.038), although no significant between\u2010group differences were observed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>Both Tai Chi and balance and postural control training alleviated pain and improved spatiotemporal parameters during stair negotiation in participants with knee osteoarthritis. However, improvements in dual\u2010task cost of cadence and speed were limited, potentially due to insufficient intervention or gait strategy adaptations. Only the balance and postural control group showed a significant reduction in dual\u2010task cost during stair descent, indicating its advantage in maintaining stability under cognitive load.<\/jats:p><jats:p><jats:bold>Trial Registration:<\/jats:bold> ChiCTR1800018028<\/jats:p><\/jats:sec>","DOI":"10.1002\/pri.70075","type":"journal-article","created":{"date-parts":[[2025,6,12]],"date-time":"2025-06-12T07:33:55Z","timestamp":1749713635000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Comparison Between Tai Chi and Balance Training on Spatiotemporal Parameters and Dual\u2010Task Costs During Stair Negotiation in Participants With Knee Osteoarthritis: A Randomized Controlled Trial"],"prefix":"10.1002","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-9739-0394","authenticated-orcid":false,"given":"Hanjing","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Rehabilitation Medicine Fujian University of Traditional Chinese Medicine  Fuzhou China"},{"name":"Key Laboratory of Orthopedics &amp; Traumatology of Traditional Chinese Medicine and Rehabilitation Ministry of Education Fujian University of Traditional Chinese Medicine  Fuzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiaqi","family":"Zheng","sequence":"additional","affiliation":[{"name":"College of Rehabilitation Medicine Fujian University of Traditional Chinese Medicine  Fuzhou China"},{"name":"Key Laboratory of Orthopedics &amp; Traumatology of Traditional Chinese Medicine and Rehabilitation Ministry of Education Fujian University of Traditional Chinese Medicine  Fuzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yatai","family":"Chai","sequence":"additional","affiliation":[{"name":"College of Rehabilitation Medicine Fujian University of Traditional Chinese Medicine  Fuzhou China"},{"name":"Key Laboratory of Orthopedics &amp; Traumatology of Traditional Chinese Medicine and Rehabilitation Ministry of Education Fujian University of Traditional Chinese Medicine  Fuzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaofei","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Rehabilitation Medicine Fujian University of Traditional Chinese Medicine  Fuzhou China"},{"name":"Key Laboratory of Orthopedics &amp; Traumatology of Traditional Chinese Medicine and Rehabilitation Ministry of Education Fujian University of Traditional Chinese Medicine  Fuzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1293-8755","authenticated-orcid":false,"given":"Xiangbin","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Rehabilitation Medicine Fujian University of Traditional Chinese Medicine  Fuzhou China"},{"name":"Key Laboratory of Orthopedics &amp; Traumatology of Traditional Chinese Medicine and Rehabilitation Ministry of Education Fujian University of Traditional Chinese Medicine  Fuzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4830-5615","authenticated-orcid":false,"given":"Meijin","family":"Hou","sequence":"additional","affiliation":[{"name":"Key Laboratory of Orthopedics &amp; Traumatology of Traditional Chinese Medicine and Rehabilitation Ministry of Education Fujian University of Traditional Chinese Medicine  Fuzhou China"},{"name":"National\u2010Local Joint Engineering Research Center of Rehabilitation Medicine Technology  Fuzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,6,12]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0268\u20100033(95)91394\u2010t"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eclinm.2020.100587"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532\u20105415.2011.03829.x"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2008.09.566"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinbiomech.2016.09.009"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/acr.21617"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1177\/0269215511421028"},{"issue":"3","key":"e_1_2_11_9_1","first-page":"4","article-title":"Long\u2010Term Tai Chi Training Is Associated With Better Dual\u2010Task Postural Control and Cognition in Aging Adults","volume":"32","author":"Jor\u2019dan A.
