1, long-term engaged in sitting work, easy to cause lumbar fatigue, the study found that in the station, lying down, sitting in three postures, in order to sit lumbar load is the largest. The method of prevention is to work for a period of time, stand up for some lumbar activities or work often change the posture, to avoid certain muscle groups for a longer period of time in a fixed contraction state. In daily life to take a sitting position, it is best to recline chair, because in the sitting position torso leaning forward 20 degrees on the lumbar disc pressure is the greatest. Long-distance car drivers can also be based on the driving situation, as appropriate, to reduce the upper body forward posture, to prevent the occurrence of lumbar disc herniation. The lumbar muscle is weak or older people should try to avoid low sitting position, such as sitting on a short stool, short sofa, soft sofa, lumbar muscle fatigue. 2, engaged in standing work when people stand for a long time, you can step on a foot in front of the counter bar, small stools, etc., so that the hip joints, knee joints, slightly bent, so as to reduce the load on the waist, reduce lumbar strain. 3, engaged in professional sports should pay more attention to the protection of the waist, every strenuous exercise before to do sufficient preparatory activities, exercise should not be immediately after the line of cold water bath, due to the expansion of blood vessels in the body, and there may be a slight muscle injury. In addition, the intensity of the exercise should be gradual, the intensity of the exercise, should be supplemented by the necessary protective measures. 4, hot water bath supplemented by massage can quickly relieve severe lumbar muscle fatigue. This method can accelerate tissue blood circulation and lymphatic reflux, promote metabolism (pain) product elimination, enhance muscle endurance. 5, sleeping position to side lying, keep the hip joints, knee joints appropriate flexion position to prevent lumbar strain is favorable, because lying on the back when the lower limbs straight, can make the lumbar vertebrae was convex position, easy to fatigue. General chronic low back pain patients should not sleep on a softer spring bed. 6, wearing high-heeled shoes will make the abdomen convex, pelvic tilt forward, accelerate the lumbar strain. When young, because of good muscle elasticity, more developed can still be compensated, after middle age, muscle relaxation can increase the burden of lumbar spine small joint capsule and cause lumbago. Especially heavy weight, large abdomen, lumbosacral angle (hip shrug), should not wear high heels. 7, appropriate physical exercise, is an important measure to prevent lumbar and leg pain. Exercise can be based on age, physical fitness, conditions and other discretionary selection of different forms. Such as a variety of gymnastics, ball, tai chi, swimming, etc. can make the muscles strong, increase endurance. Insist on doing back muscle exercises before going to bed and after getting up. Swallow point water back muscle exercises: lying down, both upper limbs on both sides of the thorax, repeatedly do the head up chest, calves and feet point backward posture), not only can prevent lumbar pain, but also on the lumbar disc protrusion after surgery to slow down the lumbar intervertebral joints continue to degenerate to ensure that the long-term efficacy of the permanence of the lumbar vertebrae instability of the symptoms and many degeneration or injury factors resulting in chronic low back pain, is also a proven method. 8, avoid cold and damp environment, pain in any part of the body will be due to cold, damp and other factors lead to local vasoconstriction and increase the pain-causing substances, thus aggravating the symptoms. 9, tall housewives, in cutting vegetables, washing dishes, laundry, pay attention to the appropriate adjustment of the height of the plate (vegetable table, washing utensils), as far as possible to avoid the accumulation of stooping action to accelerate the lumbar spine strain. 10, carrying heavy objects (such as moving laundry tubs, beer boxes) the correct posture should be in the hip and knee flexion state. This part of the force dispersed to the lower limbs, reduce the load on the waist, if the knee straight state, then all the force directly to the lumbar disc, lumbar interspinous and supraspinous ligaments, the greatest damage to the waist.
