Low back pain (LBP) is prevalent in modern society; back pain not only causes disability in daily life but also degrades the quality of life and can result in psychological problems, including depression and anxiety.Although various causes of CLBP have been reported, muscle weakness and imbalance around the lumbar spine and changes in the lumbar lordosis angle (LLA) are the main causes of CLBP.It is known that exercise intervention not only improves muscle strength around the lumbar spine but also positively changes the LLA.In addition to SSE, abdominal bracing (ABB) is effective in improving lumbar stability.
