Can incorrect standing posture lead to back pain?

Poor standing posture, especially spinal deformity, will cause uneven stress on the intervertebral disc, which is the hidden source of disc herniation. The correct standing posture should be eye-level, jaw miniature, chest out, waist straight, calf miniature and legs upright. The distance between the feet is about the same as the width of the pelvis, so that the whole pelvis will lean forward, so that the whole body's gravity will be evenly transferred from the spine and pelvis to the lower limbs, and then from the lower limbs to the feet, thus becoming a real "down-to-earth". At this time, the gravity line of the human body just passes through the lumbar body or the back of the intervertebral disc, which can effectively prevent the nucleus pulposus from protruding again.

When working, the standing posture should be: the knee joint is slightly flexed, the gluteus maximus is miniaturized, and the abdominal muscles naturally contract, which can make the pelvis slightly backward and the lumbar spine slightly straight, reduce the angle of lumbosacral angle, increase the support of the spine, and reduce the burden of the intervertebral disc.

It is impossible to stand for a long time in one posture, so it can be changed to a "at ease" posture, that is, one foot spans half a step forward, so that the weight is placed on one lower limb, the other lower limb takes a short rest, and the two sides alternate. Standing time should not be too long, and proper in-situ activities, especially waist and back activities, should be carried out to relieve muscle fatigue in the back. Once the bad standing posture is found, it should be corrected in time. A good standing posture can prevent the nucleus pulposus from protruding again to some extent.
