There are many different types of lumbar spondylosis and the causes are complex. Some of the causes are not fully understood, but degeneration of the lumbar spine and intervertebral disc itself plus trauma undoubtedly play an important role in the pathogenesis. Therefore, slowing down lumbar spine and disc degeneration and avoiding trauma is the key to preventing lumbar spondylosis. Prevention should begin with school, family, work and pre-vocational training to understand the physiology of the normal spine, maintain proper posture and pay attention to labor protection. Emphasis on early prevention, from adolescence should pay attention to avoid the occurrence of potential factors of lumbar spondylosis; perseverance, from the work environment, habits of life and other aspects to take the necessary measures; early prevention of disease, prevention and treatment combined, the early stages of lumbar spondylosis of various treatment methods of good efficacy, low recurrence rate, in the treatment process, to prevent the impact of some adverse factors, strengthen functional exercise to consolidate the effectiveness of treatment. Specific preventive measures are as follows: 1. Regular health checkups Regular health checkups, especially for adolescents, should be carried out to check for congenital or idiopathic deformities, such as idiopathic scoliosis or vertebral arch collapse. If there are such conditions in the future prone to lumbar degeneration and premature appearance of low back pain. For people who are already engaged in strenuous lumbar activities, attention should be paid to the occurrence of vertebral arch fractures, etc. If there is such a structural defect, back protection should be strengthened to prevent repeated injuries. 2, improve posture, work and rest combination Pay attention to self-regulation, avoid doing repeated fixed movements for a long time, the labor department should specify the maximum load to avoid overloading the spine, so as not to promote and accelerate degeneration. Some people who need to bend over for a long time or work for a long time, the pressure on the lumbar intervertebral disc is more than double the general standing, the incidence of low back pain and lumbar disc herniation will increase accordingly. You can change the sitting posture by constantly adjusting the height of the chair and desktop, and insist on interval exercises to restore the fatigued muscles. Correct the bad reading and writing posture of adolescents. At present, adolescents due to heavy learning load, there are generally bad reading and writing posture, if not corrected for a long time, will affect the normal development of the spine, may become the cause of low back pain in adulthood. When the human body is sitting, it is usually in two positions, namely the posterior sitting position and the anterior sitting position. Posterior sitting position, the line of gravity in the sciatic tuberosity and the back of the hip joint, the back must have a chair, this position is not easy to fatigue, suitable for rest, conversation or for reading books, but not for ambulatory writing, portrayal, etc.. When sitting in the front position, the upper body line of gravity through the front of the sciatic tuberosity or hip joint, the back muscles need to be tense to maintain the balance of sitting, which is the most commonly used sitting position. Body parts are naturally relaxed, the torso thoracic section forward about 15 degrees, the head and then from the torso forward 15 degrees, the waist lightly against the back of the chair, forearms on the table, but the elbow does not bear the weight of the torso, only to play a stabilizing role. This position can meet the needs of writing, painting, tracing and other ambulatory work, but also to reduce fatigue. Of course, the duration should not be too long, an hour can raise the head for some activities, such as hands on both sides of the waist, waist back back stretch, hands force up and down or rotate to press and push, each repeated practice 20 to 30 times, so that the practice is safe and sound, good results. When working and studying, you can constantly change position, such as moving the hips back and forth on the chair, moving the body, upper limbs and head and neck, etc., can also change the height of the chair, so that by constantly adjusting the sitting posture can reduce fatigue. 3, strengthen the spine exercise life is in motion, health is in motion. Chinese medicine has long recognized the role of physical exercise in the prevention. Modern medicine has proved that exercise can enhance the function of the heart, lungs and nervous system, so that the body is strong, energetic, and prolong life. Exercise also has a good effect on the skeletal muscle system, such as muscle attachment of the bone protrusion increases, bone density increases, muscle strength increases. Exercise improves the blood circulation of the bones, joints and ligaments, increases the metabolic process, increases the organic component of the bones, reduces the inorganic component, increases the strength and toughness of the bones, and delays the degenerative changes of the bones. Strong back muscles can prevent soft tissue damage to the low back, abdominal muscles and intercostal muscles exercise, can increase intra-abdominal pressure and thoracic pressure, help reduce the load on the lumbar spine. 4, prevention in family life Diet is an important guarantee of life and health, the spleen is the origin of the day, the main transport and transformation, the main muscle, limbs. Poor diet and damage to the spleen and stomach often affect the production of qi and blood in the body, which leads to weakness of qi and blood, loss of nourishment of tendons and bones and muscle atrophy, and can contribute to the occurrence of disease. Living is also a guarantee of human health, should be up and down sometimes, the house is moderate, so as not to lose kidney energy, loss of essence and fluid, resulting in deficiency of kidney essence, brain marrow loss of nourishment, and the occurrence of back pain disease. Domestic work should be measured, avoiding long periods of bending and bending to carry heavy objects. When ironing clothes, the height of the table should be appropriate to avoid too much bending. When lifting heavy objects, you should take a squatting position to avoid bending or twisting the waist, these are measures to reduce the load on the waist.
