Method : We Investigate the acupuncture points that was correlated with the location of thoracolumbar junction area. And We tried to find out a common point between thoracolumbar junction and back-su points, Hwatahyeopcheok points for treatment of low back pain. Results and Conclusion : 1. It is considered that these points such as $BL_{20}$, $BL_{21}$, $BL_{22}$, and Hwatahyeopcheok points that are located from 11th thoraic spinous process to 2nd lumbar spinous process are correspond to the thoracolumbar junction area. 2. It is suggested that acupuncture treatment on $BL_{20}$, $BL_{21}$, $BL_{22}$, and Hwatahyeopcheok points can release the tenderness of the muscles, recover autonomic nervous function and release smooth muscles and vascular contraction, so it can treat low back pain caused by thoracolumbar junction.
