Lumbar disc herniation is a common clinical disease, and currently 15-20% of manual laborers in China suffer from this disease. Lumbar intervertebral disc herniation is the most common clinical cause of low back pain. It should cause us to pay enough attention. In daily life, study and work, need a variety of different activities posture, developed their own habits, its correct or not on the human body has an important impact. Therefore, we are required to pay attention to the reasonableness of the usual standing posture, sitting posture, labor posture, and sleeping posture. Correct bad posture and habits, strengthen exercise, enhance physical fitness, especially strengthen the lumbar and back muscle function exercise. Because appropriate exercise can improve muscle blood circulation, stimulate metabolism, increase muscle reflection and strength, correct the spinal column internal balance and external balance of the imbalance, improve the stability of the lumbar vertebrae, flexibility and durability, thereby preventing lumbar intervertebral disc herniation. 1, the relationship between sitting posture and lumbar disc herniation In many cases, people’s sitting posture does not depend entirely on the person himself, sitting equipment on the sitting posture of the correct or not also play a certain role. Inappropriate sitting equipment can also cause back pain. Sitting on a stool, because there is no backrest, people or natural bending sitting, or sitting straight back, can make the lumbar spine to maintain a natural flexion state, lumbar muscle is relatively in a state of relaxation, at this time the stability of the lumbar spine by the lumbar spine around the ligament to maintain the lumbar lumbar vertebrae around the lumbar spine ligament easy to occur after a long period of time after sitting; straight back to sit, lumbar muscle is in a state of contraction, sitting for a long time after the lumbar and back muscles continue to contract, easy to occur, the above two situations can produce low back pain. The elderly and patients with a history of lumbar disc herniation lumbar back muscles, ligament elasticity and endurance is poor, with varying degrees of degeneration or injury, is not suitable to sit on a stool, especially not suitable to sit too low stool. Young adults are better suited to sitting on a stool because of the good elasticity and endurance of the muscles and ligaments. Chair because of the backrest, can bear part of the body’s gravity, so that the low back muscles in a relatively relaxed state, but also does not aggravate the burden of ligaments around the lumbar spine, can reduce the chance of strain. When sitting in a chair, you should pay attention to the lumbar back as close as possible to the back of the chair, work, you should pull the chair as far as possible to the table, shorten the distance between the table and chair. Since the sitting and lumbar disc herniation has a certain relationship, then what kind of sitting more appropriate? Some people have done research in this area shows that: the angle of the lumbar back rest and the lumbar have no support to rely on, on the disc pressure has a direct relationship. That is, from the state of sitting at right angles to backward tilt 120 degrees, you can make the disc pressure significantly lower, and then in the lumbar part of the 3CM thick support, can make the disc pressure to further reduce, such as this support to increase to 5CM thick, then the pressure in the disc can be reduced to -0.3Mpa. Therefore, the more appropriate seating requirements of the height of the moderate, and there is a certain angle of inclination of the backrest, such as in the lumbar part of the back of the 3-5CM thick. There are 3-5CM thick support is better. This posture is suitable for automobile drivers. 2, the correct labor posture can prevent lumbar disc herniation when laboring from the ground to lift heavy objects, such as the posture is not correct, is the most likely to cause lumbar disc injury action. The correct action should be like lifting a weightlifter to lift a barbell, squatting first, and then arms holding the weight after standing up, and then move the legs to the designated place, and then squatting to put down the weight. The incorrect action is to bend over with straight legs and hold the weight tightly with both arms, and then lower the weight after lifting it with the strength of the waist. Especially lifting at the same time in addition to the body rotation, then the lumbar spine injury is more serious. 3, lumbar disc herniation home simple treatment bed rest; own lumbar spine index.
