Objective To observe the effect of isokinetic training of knee flexors and extensors on walking ability in patients with knee osteoarthritis (KOA). MethodsFrom December, 2016 to June, 2017, 120 patients with KOA in our hospital were randomly divided into blank group (n=40), control group (n=40) and observation group (n=40). All the groups were injected with sodium hyaluronate intraluminally, and received joint mobilization. The control group added conventional strength training, including isotonic and isometric static squat exercise of muscles around the knee. The observation group received knee isokinetic training additionally, the training mode was ordinary isokinetic/centripetal mode. Before and four weeks after treatment, the peak torque (PT), the Lysholm score and Visual Analogue Scale (VAS) for pain, ten-meter walking time and six-minute walking distance were tested. ResultsAfter treatment, the PT value of knee flexors and extensors, the scores of VAS and Lysholm, ten-meter walking time and six-minute walking distance significantly improved in all groups (P<0.05), among which the observation group was the best (P<0.05).ConclusionIsokinetic muscle strength training of knee flexors and extensors can improve the walking ability of patients with KOA.
