The most important causes of lumbar disc herniation are degeneration itself and trauma. Therefore, how to delay the degeneration of the lumbar disc and avoid trauma is the fundamental way to prevent herniation. 1, strengthen the exercise of the lumbar back muscles: strong lumbar back muscles on both sides can stabilize the spine, reduce the load on the lumbar spine, increase local blood circulation, slow down the process of lumbar disc degeneration, and prevent soft tissue injury and lumbar muscle strain in the lumbar region. The common method of exercise for the lumbar back muscle is the small swallow fly. 2, maintain the correct posture of the lumbar: when the correct posture, the ligaments maintain the static balance of the spine as well as weight bearing, not easy to fatigue, and not easy to strain. In the standing and sitting position, the lower back should be kept flat, so that the waist to avoid excessive convexity. It is best to sit in a hard chair, the chair can neither be too high or too low, too high easy to make the feet off the ground, the back of the thigh muscles under pressure, affecting the relaxation of the pelvis; too low, increasing the hip flexion, so that the pelvis tilted forward, these are easy to cause lumbar muscle strain. Avoid working in a fixed position for a long time. Long-term semi-bending workers, work should keep the lower back flat, so that gravity falls on the hip joint, so that it is not easy to fatigue. 3, avoid excessive bending activities: in daily life and labor, everything should be measured to prevent lumbar sprain. When lifting heavy objects, pay attention to the balance of the body and coordination of movements, do not force to do some of the work that is not capable of. Especially people with lumbar strain should pay more attention. When bending over to take heavy objects, it is best to first bend the knee joint, and then squat to avoid excessive lumbar bending, reduce the load on the lumbar spine and reduce the possibility of disc herniation. When straightening the body, do not violently stretch the waist, to try to stretch the hips, knees, to avoid excessive force on the waist, resulting in injury. 4, pay attention to weight loss: scientific diet, weight control, do not bring excessive burden to the waist because of the body is too heavy.
