Analysis of Isokinetic Muscle Strength Measurement on the Influence of High Altitude Knee Osteoarthritis on the Knee Flexing and Stretching Muscle Groups
Objective To detect the isokinetic muscle strength characteristics of the knee joint in Tibetan patients with severe KOA and compare their differences with healthy individuals.Methods Through the isokinetic muscle strength testing and training system,For 20 patients with unilateral right knee osteoarthritis(observation group)and 20 healthy individuals(control group)were tested for isokinetic centripetal muscle strength at different angles of the knee joint(60°/s and 180°/s),and the observation indicators were compared and analyzed.Results Under different angular velocities,the PT of the flexor and extensor muscles in the right knee(affected side)of the observation group was lower than that in the left knee(healthy side)and control group,the differences between groups were statistically significant(P＜0.05);the PT and BW of the 180 °/s flexor and extensor muscle groups in both groups were lower than those in the 60 °/s flexor and extensor muscle groups,the differences between groups were statistically significant(P＜0.05).Conclusion The muscle function of both healthy and affected knee joints in patients is worse than that of healthy individuals,with the most significant decrease in muscle function of the affected knee joint being the flexor muscle.
