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. The human spine is composed of a number of vertebrae, two vertebrae have a disc-shaped elastic pad, surrounded by fibrous rings and ligaments fixed, this disc-shaped pad is what we call the intervertebral disc. It can play the role of cushioning pressure. Humans are upright animals, the intervertebral discs are subjected to greater pressure when standing, especially the lumbar intervertebral discs are more pronounced, and therefore have more chances of being injured. The human body with age or acute trauma and chronic accumulation of trauma and other reasons leading to the rupture of the annulus fibrosus, resulting in intervertebral disc prolapse compression of the spine on both sides of the nerve root surface caused by sciatica and a series of low back and leg pain symptoms is a common orthopedic disease – lumbar intervertebral disc herniation. This disease is not unfamiliar to our readers. Patients feel that it is very painful, difficult to treat and easy to recur. Starting from daily life, keep away from lumbar disc herniation. In daily life, study and work, need a variety of different activities posture, developed their own habits, its correctness or not has an important impact on the human body. Therefore, we are required to pay attention to the reasonableness of our usual standing, sitting and labor postures, as well as sleeping postures. 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 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 correct or not also play a 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, so that the lumbar spine to maintain a natural state of flexion, the 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 vertebrae ligaments are prone to strain injury after sitting for long periods of time; sitting straight back, lumbar muscle is in a state of contraction, sitting for a long time lumbar and back muscles continue to contraction, prone to strain injury, 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 medium-low, and there is a certain angle of inclination of the backrest, such as the lumbar part of the 3-5CM thick back support. There are 3-5CM thick support is better. This posture is suitable for car drivers sitting. 2, the correct labor posture can prevent lumbar disc herniation: labor from the ground to lift heavy objects, such as posture is not correct, is most likely to cause lumbar disc injury action. The correct action should be like weightlifters lift a barbell, squatting first, and then arms holding the weight after standing up, and then move the legs to carry to the designated location, and then squatting 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, strengthen the lumbar back muscle exercise: lumbar back muscle exercise methods are many, but in the family can do, and more focused on the following three methods: ① space car ② back to walk ③ prone position back muscle exercise. Lumbar disc herniation home simple treatment 1, bed rest: the use of bed rest to treat lumbar disc herniation, the method is relatively simple, the patient does not need too much professional knowledge, can be carried out at home. However, there are still many problems that should be paid attention to in bed rest, and if they are not solved well, the therapeutic effect cannot be guaranteed. ① Bed rest requires a hard bed. Specifically, it is a wooden bed with a thin mattress or cushion, the harder brown bed can also be. ② patients lying on their backs, you can add another thin pad in the waist or make the knees, hips to maintain a certain degree of flexion, so that the muscles can be fully relaxed. Prone position, the mattress should be flat, so as to avoid excessive lumbar extension. ③ Bed rest should be strictly adhered to. Even after the symptoms are relieved for a period of time to wear a waist cuff to get out of bed, can not do any lumbar flexion. If the patient is unable to insist on bed rest due to the inconvenience of life, the therapeutic effect will be affected. ④ The most difficult thing to adhere to in bed rest is to urinate and defecate in bed. If the patient can not accept the flat lying position to urinate and defecate, you can support the crutches or be assisted to go down to the toilet. Do not sit up in bed to defecate, because then the lumbar excessively forward flexion, the disc is more likely to protrude back. Of course, after a period of time in bed, such as with massage, acupuncture, physiotherapy and other methods of integrated treatment, will achieve better results. 2, their own lumbar traction: this kind of lumbar traction does not need traction equipment, but from their own body weight to achieve lumbar traction role is simple and easy to grasp. ① bed own traction ② sofa own traction lumbar traction above are about 15-20 minutes appropriate.
