Straightening of the physiological curvature of the lumbar spine needs to be restored through exercise rehabilitation, which can exercise the muscles around the pelvis and the lumbar spine. Stretching exercises can relax the stiff muscles; strengthening exercises can strengthen the weaker muscles and gradually restore the flexibility and stability of the pelvis and the lumbar spine. The lumbar spine is driven by the contraction movement of the muscles, thus gradually restoring the physiological curvature of the lumbar spine, e.g. supine abdominal flexion exercise, clam stretching, cobra stretching exercise etc. However, if structural changes have occurred, such as compression and flattening of the vertebral body, resulting in kyphosis and flat back deformity, then surgery is needed to correct the problem, otherwise, the effect of simple exercise rehabilitation is not very satisfactory. It is recommended that patients seek timely medical attention and follow the doctor’s instructions, and do not blindly exercise on their own to avoid delaying their condition.
