Abstract:Objective: To explore the effect of isokinetic exercise combined with proprioceptive training on knee flexion and extensor strength, coordination and limb balance function in patients with knee osteoarthritis. Methods: 60 patients with knee osteoarthritis were selected from the Department of Rehabilitation Medicine, Qingdao Binhai University affiliated Hospital. The patients were randomly divided into 3 groups (n = 20). Group A was treated with physical factor therapy and routine exercise therapy, group B was treated with physical factor therapy and isokinetic concentric combined eccentric muscle strength training, and group C was treated with proprioceptive training on the basis of group B. The peak torque (PT), the ratio of flexion to extensor force (H/Q) and the active angle reappearance value (AAR) were measured by isokinetic tester before and after treatment; balance training instrument was used to measure the time-consuming (Time) and average trajectory error (ATE) before and after treatment; knee joint pain and quality of life were evaluated with VAS and WOMAC scale before and after treatment. Results: After training, the isokinetic index, dynamic balance index, VAS and WOMAC were significantly improved in the three groups(P<0.05). Pairwise comparison of PT and H/Q after treatment, C=B>A. There were significant differences between groups of AAR and Time (P<0.05), C>B>A. After treatment, the ATE value was pairwise compared, C>B=A. The comparison between groups was statistically significant of VAS score and WOMAC score after treatment (P<0.05), C>B>A. There were no adverse reactions in the three groups during the treatment period. Conclusion: Isokinetic concentric combined eccentric training can reduce the pain of patients with knee osteoarthritis, enhance the muscle strength and coordination of knee flexion and extensor, and improve the function of knee joint.
