A deep depression in the posterior lumbar region may be physiologic, and does not require treatment if there are no uncomfortable symptoms; it may also be related to abnormalities in the physiologic curvature of the lumbar spine, and requires a choice of treatment options based on the resulting clinical symptoms, such as exercise therapy, physical factor therapy, or surgical treatment. The normal human lumbar spine has a physiological curvature, and a certain depression in the posterior lumbar region is physiological and does not require treatment if there are no abnormal symptoms. If the depression is deep and accompanied by discomfort such as lumbar pain, it may be related to the abnormal change of lumbar spine curvature and can be treated according to the doctor’s instructions. 1. Exercise therapy: the core muscles of the lumbar spine can be trained, and at the same time, the muscles and soft tissues around the lumbar spine can be pulled appropriately, so as to correct the phenomenon of abnormal depression of the lumbar spine. 2. Physical factor therapy: you can choose the method of intermediate frequency electrical stimulation with local magnetic heat therapy to relax the muscles and promote blood circulation, which can relieve the pain. 3. Surgical treatment: If the depression in the lower back is very deep, and obvious structural changes of the lumbar spine have occurred, and the patient has functional problems such as limited lumbar spine movement, it is necessary to consider corrective treatment through surgical methods to rebuild the structure of the lumbar spine. The treatment of deep lumbar depression needs to be carried out under the guidance of professional physicians, and usually pay attention to maintaining good posture in daily life, so as not to affect the therapeutic effect.
