Although the strength of the quadriceps\u2014a muscle used to extend the knee\u2014has been deemed to have a significant effect on postoperative gait function in TKA patients, there are many cases in which gait function does not improve even after quadriceps strength is restored. This raises a need to identify other factors influencing gait function.<\/p>\n\n\n\n
A research team led by Professor Akira Iwata, from the Graduate School of Rehabilitation Science at Osaka Metropolitan University, hypothesized that the movement velocity of knee extension (i.e., knee extension velocity) is a strong determinant of gait function in TKA patients, and tested this hypothesis on 186 elderly patients who underwent TKA. <\/p>\n\n\n\n
Measurements were taken before and at 2 and 3 weeks after surgery and included gait function (gait speed and Timed Up and Go test), knee extension velocity, quadriceps strength, knee range of motion, and knee pain. Multiple regression analysis was performed to analyze the relationship between gait function and other variables.<\/p>\n\n\n\n
The results show that the knee extension velocity on the operated side was the most important predictor of gait function in the participating patients. The findings were published in PLOS ONE<\/em><\/a>.<\/p>\n\n\n\n \u201cThus far, rehabilitation programs aimed at recovering gait function after TKA surgery have focused on training to improve quadriceps strength,\u201d explained Professor Iwata. <\/p>\n\n\n\n \u201cHowever, this study\u2019s results suggest that training to enhance knee extension velocity on the operated side could be effective. We will continue to examine the effects of rehabilitation that concentrates on movement velocity.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":" \u201cSpeed or strength, which is more important?\u201d may be a critical question for not only athletes but also knee surgery patients. <\/p>\n","protected":false},"author":2,"featured_media":23764,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6,17],"tags":[],"class_list":["post-23763","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-health","category-research"],"featured_image_urls":{"full":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy.png",680,524,false],"thumbnail":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy-200x200.png",200,200,true],"medium":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy-519x400.png",519,400,true],"medium_large":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy.png",680,524,false],"large":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy-675x520.png",675,520,true],"1536x1536":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy.png",680,524,false],"2048x2048":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy.png",680,524,false],"ultp_layout_landscape_large":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy.png",680,524,false],"ultp_layout_landscape":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy.png",680,524,false],"ultp_layout_portrait":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy-600x524.png",600,524,true],"ultp_layout_square":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy-600x524.png",600,524,true],"newspaper-x-single-post":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy-680x490.png",680,490,true],"newspaper-x-recent-post-big":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy-550x360.png",550,360,true],"newspaper-x-recent-post-list-image":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy-95x65.png",95,65,true],"web-stories-poster-portrait":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy.png",640,493,false],"web-stories-publisher-logo":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy.png",96,74,false],"web-stories-thumbnail":["https:\/\/www.revoscience.com\/en\/wp-content\/uploads\/2023\/01\/knee-therapy.png",150,116,false]},"author_info":{"info":["RevoScience"]},"category_info":"Health<\/a> Research<\/a>","tag_info":"Research","comment_count":"0","_links":{"self":[{"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/posts\/23763","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/comments?post=23763"}],"version-history":[{"count":0,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/posts\/23763\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/media\/23764"}],"wp:attachment":[{"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/media?parent=23763"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/categories?post=23763"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.revoscience.com\/en\/wp-json\/wp\/v2\/tags?post=23763"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
