Purpose : The purpose of this study is to investigate the effect of squat exercise using a ball on the gap between knees and Q angle of a subject with a genu-varum, and to prove the effect, to provide a clinical basis for developing into a knee correction exercise program.
Methods : As a result of posture measurement through GPS, 26 female with genu-varum with a knee length of 5 cm or more were studied. The group was randomly assigned to 13 squat exercise group using ball(experimental group) and 13 general squat exercise groups(control group). The experimental group placed the ball between both knees in a position where the distance between both feet was slightly wider than the shoulder width on a flat support surface, and fixed the ball, and then squat with the start signal. The control group squats without a ball. Each group performed three sets of exercise three times a week for six weeks. Before their exercise, after three and six weeks, EMG, GPS, digital goniometer measurement, the vastus medialis (VM), the vastus lateralis (VL), and the Q-angle were measured in the squat exercise posture. EMG was measured in squat exercise posture.
Results : The distance between the knees was reduced. EMG is activated in group A, the group B experimental results showed the high activity of the VL. Q-angle had increased. But the experimental group increased more than the control group.
Conclusion : We have confirmed through our experiments that the distance interval between the knees during squat exercises using a ball can be reduced. Furthermore, it would also be helpful to ensure the treatment of genu-varum.
