Research Abstract	We verified whether woman with knee pain have physiology changes of lower extremity muscle during one leg standing motion. This research had become clear as following things. 1.We had observed SSP of Gluteus medius during one leg standing motion. However, we had identified variability at the incidence of SSP among individuals. 2.During one leg standing motion, Gluteus medius EMG increased in in subjects with knee pain. There were no differences in SSP variables between subjects with knee pain and control subjects. Further investigation is warranted regarding SSP changes at elderly women with knee pain.
