With the popularity of mechanization and office computers, people who work in a sitting position are becoming more and more popular. In order to prevent low back pain, some sedentary people often put a cushion on the car chair, sofa and stool. The doctor reminded that using cushions to prevent low back pain should also pay attention to methods.

The doctor pointed out: First of all, the cushion must be placed on the waist, and it is not correct to put it on the back. This is because the normal human body has a total of 5 lumbar vertebrae. Due to physiological requirements, they do not grow in a straight line, but a convex shape that protrudes forward from the middle. From the side, the lumbar vertebrae is like a gently sloping packet. Due to this physiological feature, the waist and back cannot be placed in the same plane. Therefore, the correct sitting posture should be, chest up, when the chair is needed, the waist is straight, leaving the back of the chair, sitting on the sofa as much as possible. Let the hips sit on the bottom of the sofa and the back against the back of the sofa. If a cushion is placed on the waist, the waist can be effectively supported, maintain the flexion of the lumbar vertebrae, balance the pressure of the lumbar vertebrae and lumbar muscles, reduce strain, increase the comfort of the body, prevent and improve lumbar discomfort, and stabilize the spine. benefit. Secondly, the cushions should not be too thick. It is better to use a cushion of 10 cm height. In this way, the human body presses backward, just compressing 5-8 cm, which is most suitable for the physiological lordosis of the lumbar spine. Too thick will cause excessive flexion of the lumbar spine.
