It is reported that low back pain is related to erector spinae muscle. The purpose of this study was to investigate that between subjects who have low back pain and who don't have low back pain on four different sit positions that have stability difference by comparing for effect on the thickness change of erector spinae muscle. The study collects 15-people who were diagnosed that was not operated because of a medical or surgical disease without low back pain and who were diagnosed. It measures the thickness of erector spinae muscle by real-time ultrasonopaphy, according to prone position, sitting on a chair position, sitting on a gymball position and sitting on a gymball with left leg rising. There were significant difference for the thickness of erector spinae muscle in prone position, sitting on a chair, sitting on a gymball (p<.05). However, there were no significant difference in sitting on a gymball with left leg rising (p>.05). This study demonstrated that the lower stability position, the more effects on the thickness of erector spinae muscle.
