Stability is also known as “balance” for the spine, and any balance is relative and conditional. Stability of the spine is also a relative stability, a prerequisite and basic condition for proper spinal function. The stability of the spine depends on both internal and external aspects. Internal is mainly the curvature and neutrality of the spine, vertebrae, intervertebral discs, small joints, and paravertebral ligaments; external is mainly muscles and fascia. (1) the internal balance of the spine (1) the curvature and neutrality of the spine: the basic physiological function of the spine determines that the spine needs to grow in accordance with DNA information into a neutrality with S-shaped physiological curvature, perpendicular to the center of gravity, so as to ensure that the spine can be in a stable state in both static and dynamic conditions; (2) vertebrae: the basic unit of the spine, the shape, structure and position of each vertebrae (3) intervertebral discs: the vertebral body of the vertebrae and the vertebral body of the vertebrae are tightly fixed together by the intervertebral discs, which can also effectively absorb shocks, and the intervertebral discs play a very important role in stabilizing the spine; (4) small joints: also known as synovial joints, are important weight-bearing and supporting structures at the back of the spine (5) paravertebral ligaments: the ligaments start and end at the adjacent vertebral structures, which play an important role in spinal motion and stability, and the role of the ligaments in limiting excessive displacement between vertebrae is very obvious. 2, the external balance structure of the spine Muscles and fascia around the spine: muscles and fascia are closely linked and are the only external factors related to the stability of the spine. Changes in the stability of the spine are very closely related to the muscles around the spine, and any changes in muscle strength and movement disorders related to spinal movement will lead to changes in the stability of the spine. 3, the importance of the balance of the spine and stability of the structure of the spine balance is an important condition for maintaining human health. The spine is located in the middle of the body, supporting the head, sitting on the pelvis, outreach limbs, spinal nerves through which. In front of the spine there are three chambers of the body: the heart and lungs are on top, the liver, gallbladder and spleen on both sides, the stomach, small intestine, pancreas and kidneys on the back, and the bladder and uterus on the bottom, each in its own place. The spine has nerve connections with various organs, is connected by blood vessels, and is supported by muscles and ligaments. When the spine is affected by degeneration, injury, exertion, inflammation, tumors, and poor movement, it inevitably becomes twisted and deformed. When the spine is out of balance, the spinal ligaments and visceral ligaments twist, blood flow in the blood vessels is obstructed, nerves are stimulated or compressed, and this series of changes inevitably causes abnormal function of the visceral organs and, in the long run, can cause organic lesions of the organs. Theoretically, a balanced spine and healthy internal organs will result in a naturally graceful and proportionate physique and a light and steady gait.
