Lumbar disc herniation is a common clinical condition that currently affects 15-20% of manual workers in China. Lumbar disc herniation is the most common cause of back and leg pain in clinical practice. It should cause us enough attention. The human spine is composed of several vertebrae, and there is a disc-shaped elastic cushion between two vertebrae, which is fixed by the fiber ring and ligaments around it, and this disc-shaped cushion is what we call intervertebral disc. It can play the role of cushioning pressure. Humans are upright animals, the greater the pressure on the intervertebral disc when standing, especially the lumbar intervertebral disc is more obvious, so the chance of injury is more. The human body with the growth of age or acute trauma and chronic accumulation of trauma and other reasons lead to rupture of the annulus fibrosus, resulting in disc prolapse compression of the nerve root surface on both sides of the spine caused by a series of sciatica and other symptoms of low back pain, is a common orthopedic disease – lumbar disc herniation. This disease is not new to our readers. Patients feel that it is very painful, difficult to treat and easy to recur. Start from daily life to stay away from lumbar disc herniation. In daily life, study and work, a variety of different activity postures are required, and the respective habits are developed, the correctness of which has an important impact on the human body. Therefore, we are required to pay attention to the rationality of our usual standing, sitting, and labor postures, as well as sleep postures. Correct bad posture and habits, strengthen exercise, enhance physical fitness, especially to strengthen the functional exercise of the lumbar and back muscles. Because proper exercise can improve muscle blood circulation, stimulate metabolism, increase muscle reflectivity and strength, correct the imbalance between the intrinsic and extrinsic balance of the spine, improve the stability, flexibility and durability of the lumbar spine, thus playing a preventive role against lumbar disc herniation. 1, sitting posture and the relationship between lumbar disc herniation: In many cases, the person’s sitting posture does not depend entirely on the person himself, sitting tools also play a role in the correct sitting posture or not. Inappropriate seating equipment can also cause lumbar pain. When sitting on a stool, because there is no backrest, people or naturally bend over, or straight waist sitting, can make the lumbar vertebrae to maintain a natural flexion state, lumbar muscle is relatively in a relaxed state, the stability of the lumbar vertebrae by the ligaments around the lumbar vertebrae to maintain, ligaments around the lumbar vertebrae after sitting prone to strain; straight waist sitting, lumbar muscle in a contracted state, after sitting lumbar back muscle continues to contract, prone to strain, both of these cases can produce lumbago. Older people and patients with a history of lumbar disc herniation lumbar back muscles, ligament elasticity and endurance is poor, there are varying degrees of degeneration or injury, not suitable for sitting stool, especially not suitable for sitting too low stool. Young adults are more suitable for sitting on a stool because of the elasticity and endurance of muscles and ligaments. Chair because of the backrest, can bear part of the body’s gravity, so that the lumbar muscles in a relatively relaxed state, but also does not increase the burden of ligaments around the lumbar spine, can reduce the chance of strain injury. When sitting in a chair, attention should be paid to the lumbar back as close as possible to the back of the chair, when working, the chair should be pulled as far as possible to the table, shorten the distance between the table and chair. Since the sitting furniture and lumbar disc herniation has a certain relationship, then what kind of sitting furniture is more appropriate? Some people have done research in this area: the angle of the lumbar back at rest and the waist with or without support to rely on, the disc pressure has a direct relationship. Therefore, the more suitable sitting furniture requires a moderate height, and a certain inclination of the backrest, such as in the waist There are 3-5CM thick support is better. This posture is suitable for car drivers sitting posture. 2, the correct labor posture can prevent lumbar disc herniation: labor from the ground to lift heavy objects, such as incorrect posture, is the most likely to cause lumbar disc injury action. The correct action should be like a weightlifter lifting a barbell, first squatting, then standing up after holding the weight with both arms, then moving the legs to the designated place, then squatting to put down the weight. Incorrect action is straight legs bent over arms grip after the weight, the strength of the waist to lift the weight after the drop. Especially lifting things at the same time in addition to 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 methods are the following three: ① space bike ② back to walk ③ prone position back muscle exercise. The simple home treatment of lumbar disc herniation 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 expertise, you can do at home. However, there are still many problems that should be noted in bed rest, and if they are not solved properly, the therapeutic effect cannot be guaranteed. ① Bed rest requires a hard bed. Specifically, a thin mattress or mat on a wooden bed, or a hard brown bed is also acceptable. ② When the patient is lying on his back, he can add another thin pad at the waist or keep the knees and hips in a certain degree of flexion, so that the muscles can be fully relaxed. In prone position, the mattress should be flat to avoid excessive lumbar back extension. ③ Bed rest should be strictly adhered to. Even after the symptoms are relieved for a period of time, wear a waist brace and get out of bed, you should not do any waist flexion. If the patient cannot adhere to bed rest due to inconvenience in life, it will affect the efficacy of treatment. ④ The most difficult part of bed rest to adhere to is defecating and urinating in bed. If the patient can’t accept the flat position to defecate or urinate, he can hold the crutches or be assisted to go down to the toilet. Do not sit up in bed to defecate, because then the waist is excessively forward-flexed, the intervertebral disc is more likely to posterior protrusion. Of course, after a period of time in bed, such as with massage, acupuncture, physical therapy and other methods of comprehensive treatment, will achieve better results. 2, self-lumbar index: this kind of lumbar index does not need indexing apparatus treatment, but from their own weight to achieve the lumbar indexing role is simple and easy to grasp. ① bed self-index ② sofa self-index
