Normal curvature of lumbar spine

Our lumbar spine can be said to be very flexible, especially for those who often practice dancing. Their waist can bend 180 degrees. The waist of a normal person can also bend to 90 degrees. But for those who often sit to work and have lumbar diseases, when they bend over, they will feel back pain because bone spurs will cause them severe pain. So what is the degree of bending of the lumbar spine of a normal person?

The straightening of the physiological curvature of the lumbar spine is also called "straightening of the lumbar curvature". It is a change in lumbar lesions that often accompanies various lumbar diseases. It is generally recommended that patients receive physical therapy and traction, or combine physical therapy and traction with acupuncture and massage treatment. This method is more effective. At the same time, patients should avoid sitting for long periods of time, bending less, and not lifting heavy objects.

The straightening of the physiological curvature of the lumbar spine is also called "straightening of the lumbar curvature". It is a change in lumbar lesions that often accompanies various lumbar diseases. Patients with lumbar diseases often find that the physiological curvature of the lumbar spine changes to varying degrees after undergoing lumbar examinations such as X-rays and CT scans. The normal lumbar spine forms a forward curvature in the sagittal plane (i.e. viewed from the side). The physiological curvature of the lumbar spine can make the spine elastic, cushioning and dispersing the vibration impact of movement on the torso. When the physiological curvature of the lumbar spine becomes straight, the patient's trunk is extremely susceptible to vibration and injury. In addition, as the physiological curvature of the lumbar spine becomes straightened, the structure between the lumbar joints will change, resulting in common clinical manifestations of lumbar diseases.

The straightening of the physiological curvature of the lumbar spine will lead to changes in the lumbar structure, which in turn affects the muscles, ligaments, nerves and other tissues near the lumbar spine, resulting in corresponding clinical manifestations. After the physiological curvature of the lumbar spine becomes straightened, the muscles that fix the lumbar structure need to be in a tense and stretched state for a long time in order to continue to maintain the function of fixing the lumbar spine. Therefore, patients whose lumbar spine curvature becomes straight are very likely to experience symptoms of lower back pain and discomfort. When the physiological curvature of the lumbar spine becomes straightened, the nerves, blood vessels and other tissues passing through the lumbar spine are compressed or stimulated, and symptoms such as low back pain, pain, numbness and loss of sensation in the lower limbs will occur. When the lumbar curve becomes straight and the cauda equina is compressed, symptoms such as urinary and bowel dysfunction and incomplete paralysis of the lower limbs may also occur.

The straightening of the lumbar spine's physiological curvature is mostly caused by long-term unreasonable posture. The initial symptoms are just incorrect posture, hunchback and local excessive force, which will cause chronic damage to the soft tissue over time and lead to chronic low back pain such as lumbar muscle strain, so it is also called postural low back pain. The straightening of the physiological curvature of the lumbar spine is the result of further accumulation on this basis. Therefore, correcting posture is the key among the keys, and reasonable posture is the basis and prerequisite for rehabilitation exercises. Otherwise, if the cause of the disease is not resolved, it will only recur, forming a vicious cycle and becoming increasingly serious.

Maintaining a sitting position or other postures for a long time will cause fatigue and damage to the ligaments, muscles and other tissues around the lumbar spine, reduce the stability of the joints between the lumbar vertebrae, and easily induce the straightening of the physiological curvature of the lumbar spine. Therefore, people who work in a fixed posture for a long time should change their body position in time and exercise to effectively prevent the occurrence of straightening of the physiological curvature of the lumbar spine.
