Abstract

The aim of this study was to identify the effects of a corrective exercise program on landing ground reaction force characteristics and lower limb kinematics in older adults with genu valgus. Twenty six older male adults with genu valgus were randomized into two groups. An experimental group conducted a 14- week corrective exercise program, while a control group did not perform any exercise. The experimental group displayed lower peak vertical, peak anterior and posterior, and peak medial ground reaction force components during the post-test compared to the pre-test. The vertical loading rate, impulses, and free moment amplitudes were not statistically different between groups. In the experimental group, the peak knee abduction during the post-test was significantly smaller and the peak hip flexion angle was significantly greater than during the pre-test. We suggest that this corrective exercise program may be a suitable intervention to improve landing ground reaction forces and lower limb kinematics in older male adults with genu valgus.
