Office family, teachers, salesmen, farmers …… involved in all walks of life of the population almost all have occurred lumbar discomfort, even lumbar muscle strain or lumbar disc herniation and so on. According to statistics, lumbar intervertebral disc herniation has appeared in recent years the trend of aging, the current incidence of lumbar intervertebral disc herniation has been nearly 15%, leading to lumbar intervertebral disc degenerative changes in the main reason for the long-term chronic cumulative strain, in addition to the occupational reasons, diseases or external injuries caused by their own health care awareness is not strong, usually occur in life habitual use of the wrong waist is more than a few cases. 1, office workers, car drivers and other sedentary people sedentary, coupled with incorrect posture is one of the prominent causes of lumbar spine disease. The load of the lumbar spine when sitting is greater than when standing, when the pelvis is tilted back, the lumbar vertebrae anterior convexity disappeared, the center of gravity of the body moved to the front of the spine, the intervertebral discs are under great pressure. Studies have shown that the human body in the forward leaning 20 degrees sitting position, the lumbar intervertebral discs within the maximum pressure. This is exactly the posture often maintained when working at a desk. Scientists have found that the intrinsic frequency of the lumbosacral region and the vibration of the driver’s seat are in the same low-frequency range, so the lumbar spine can easily resonate with the car when driving. This resonance means that the spine is constantly being compressed and stretched, while the surrounding tissues and muscles are also followed by fatigue, will accelerate the degeneration of the lumbar spine, deformation. Correct sitting posture should be the upper body straight, abdominal, sedentary, it is best to every 40 minutes or so activities, such as chest expansion exercise, backward waist, upward pulling and so on. In addition, the lumbar disc protrusion (bulging) patients should not sit below 20 centimeters of the short stool, it is recommended to sit in a chair with a lumbar support, the lumbar anterior convex close to the upright position, the load is also relatively small, so that the lumbosacral region will not be too fatigue. 2, teachers, salesmen and other people standing for a long time as a teacher, often need to board books, and need to side waist from time to time to turn waist and student interaction. The salesman, work regulations must stand service, need to side waist at any time to turn waist and customer communication or take goods. At the same time to adapt to the height of the podium or counter, long time to keep bending or waist forward posture, lumbar load increases, lumbar muscle is also in a state of tension for a long time. When suddenly twisting the waist often may damage the lumbar muscles and lumbar intervertebral discs. This group of people should try to avoid wearing high heels, so as not to shift the center of gravity of the body forward. At the same time, chest and abdomen, to keep the body upright. If you need to keep bending or leaning forward for a long time, you can use both upper limbs to support the weight of the upper body and reduce the load on the lower back. If you have been tortured by back pain, you should also check whether the height of the podium or counter is appropriate, generally should be matched with their height, standing height and hip level is appropriate. 3, farmers and other farmers to maintain a stooped posture Farmers planting, housewives do housework, often have to maintain a stooped posture, over the years it is easy to cause cumulative damage, and evolved into chronic symptoms. These patients are prone to fatigue due to excessive stretching of the back muscles, resulting in sore back pain, as if someone is pulling on the muscles. It is recommended to use long-handled tools, such as plowing, mopping the floor will appear bending action, you can choose a longer handle, try to use the elbow movement to compensate for the angle of bending needed. If the work takes a long time, about 20 minutes or so, then get up and do a simple stretching exercise and then continue, so as to avoid long-term muscle tension, you can get a chance to relax. Lifting heavy objects should be straight back, bed rest should lie flat on a hard bed, when lying on his back on a bed, the spine in the role of the bed to maintain physiological curvature, the lumbar muscles in a state of rest, can get a good recovery, will not aggravate the spinal injury, it is worth advocating. In the face of the increasingly large group of patients with low back pain, it is recommended that the golden treatment period is within 3 months of the onset of the disease, before seeking timely help from a doctor to treat the most likely to recover.
