The purpose of this study men and women 20 to 30 of 16 patients wearing thick insoles 5cm before and after squat exercise based on the angle of the knee joint(0-, 60-, 90-degree) was to observe the muscle activities. For this through the analysis of the rectus femoris EMG, vatus medialis vatus lateralis, tibialis anterior, gastrocnemius MVIC were quantified using. The results following results were obtained. After wearing the thick insole standing position(0') had increased EMG activity of vastus lateralis muscle, the knee angle is rectus femoris, vatus medialis, vastus lateralis, tibialis anterior, gastrocnemius muscles were increased muscle activity. thick insole of the ankle joint, causing plantar flexion forward weight distritbution by focusing is normally the body would lead to an array. When an array of everyday life, these abnormalities increases energy consumption, and muscle fatigue, increase will cause an imbalance in the muscles. Therefore, wearing thick insoles by changing the activity of the muscles may cause knee pain.
