The present study aimed to investigate the effect of the shoe’s external insole with different inclination percentages on the knee’s external adduction torque and its impulse in individuals with genu varum. Kinetic and kinematic indices of the knee joint during running calculated by inverse dynamic method with barefoot, no insoles shoes, and shoes having 0, 5, and 10 degrees of external slopes insoles. The results showed a significant difference in the amount of torque peak and adduction torque impulse of the knee, between insoles; as the insoles of 5- and 10-degrees external slopes, caused a significant decrease of variables compared to bare foot, no insoles shoes, and zero-degree slope insoles shoes. Thus, external slope insoles are suggested as an effective and non-invasive approach for preventing musculoskeletal disorders such as osteoarthritis related to inconsistency of genu varum in affected people.
