The sit-to-stand (STS) task primarily uses the strength of the knee extensor muscles. The five times sit-to-stand test (FTSST) is often applied to determine lower limb function and the results are related to lower extremity muscle strength. This study explored the cut-off point for knee extensor muscle strength in patients with iSCI to independently determine their FTSST results and the correlation between knee extensor muscle strength and FTSST results.  Methods: Forty-four participants were assessed for knee extensor muscle strength using a hand-held dynamometer (HHD) and the FTSST.  Results: The data indicated that knee extensor muscle strength \u2265 53.06 Newton was the best independent predictor of the FTSST results (sensitivity 72.7%, specificity 72.7%). Moreover, knee extensor muscle strength was significant and correlated with the FTSST results (r = \u25000.45, P = 0.035).  Conclusion: The findings offer a cut-off point for the knee extensor muscle strength measured while standing up from a chair that may help medical professionals set rehabilitation goals for patients with iSCI.<\/jats:p>","DOI":"10.21315\/mjms2022.29.5.8","type":"journal-article","created":{"date-parts":[[2022,11,3]],"date-time":"2022-11-03T06:46:42Z","timestamp":1667458002000},"page":"74-82","source":"Crossref","is-referenced-by-count":4,"title":["Knee Extensor Muscle Strength to Measure the Ability of Five Times Sit to Stand Independently in Patients with Incomplete Spinal Cord Injury"],"prefix":"10.21315","volume":"29","author":[{"name":"School of Physical Therapy, Faculty of Associated Medical Sciences, Khon Kaen University, Khon Kaen, Thailand","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lugkana","family":"Mato","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Improvement of Physical Performance and Quality of Life (IPQ) Research Group, Khon Kaen University, Thailand","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nanniphada","family":"Chankavee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"School of Physical Therapy, Faculty of Associated Medical Sciences, Khon Kaen University, Khon Kaen, Thailand","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Improvement of Physical Performance and Quality of Life (IPQ) Research Group, Khon Kaen University, Thailand","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sugalya","family":"Amatachaya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"School of Physical Therapy, Faculty of Associated Medical Sciences, Khon Kaen University, Khon Kaen, Thailand","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Improvement of Physical Performance and Quality of Life (IPQ) Research Group, Khon Kaen University, Thailand","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thiwabhorn","family":"Thaweewannakij","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"School of Physical Therapy, Faculty of Associated Medical Sciences, Khon Kaen University, Khon Kaen, Thailand","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Improvement of Physical Performance and Quality of Life (IPQ) Research Group, Khon Kaen University, Thailand","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"8963","published-online":{"date-parts":[[2022,10,28]]},"container-title":["Malaysian Journal of Medical Sciences"],"original-title":[],"deposited":{"date-parts":[[2022,11,3]],"date-time":"2022-11-03T06:46:53Z","timestamp":1667458013000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.mjms.usm.my\/MJMS29052022\/MJMS29052022_08.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,10,28]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2022,10,28]]}},"URL":"https:\/\/doi.org\/10.21315\/mjms2022.29.5.8","relation":{},"ISSN":["1394-195X","2180-4303"],"issn-type":[{"value":"1394-195X","type":"print"},{"value":"2180-4303","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,10,28]]}}}
