Lumbar disc herniation is most common in young adults of working age, and in most cases, it is a chronic process from quantitative to qualitative changes. In daily work and life, improper body position or posture can cause the lumbar discs to be repeatedly subjected to excessive extrusion, torsion and other loads, resulting in microscopic damage to the discs. Long-term repeated accumulative injury can cause the lumbar intervertebral disc damage increasing, the nucleus pulposus of the intervertebral disc degeneration, and then in the case of sudden increase in abdominal pressure such as sneezing or laughing, or sudden force on the waist, lumbar sprain, etc., can make the intervertebral disc with small damage suddenly rupture and prolapse, compressing the lumbar nerve roots, causing severe lumbar pain, and even pain and numbness radiating to one lower limb and other more serious This is the acute attack of lumbar disc herniation. After the lumbar disc herniation, although the symptoms can be relieved after conservative treatment, but the lumbar sustained strain or again after minor trauma can be repeatedly aggravated, so that the condition repeatedly leads to the patient’s pain and suffering, which can seriously affect work and life, and even requires surgery in severe cases. Therefore, for people who have already experienced low back pain or lumbar disc herniation, it is very important to strengthen the protection of lumbar function and functional exercise. Effective functional protection and exercise of the muscles of the low back can help maintain lumbar stability and can effectively prevent acute and chronic lumbar injuries and low back pain, which is especially important for patients who have had acute and chronic lumbar muscle injuries or lumbar disc herniation and are currently in remission. Cold and humidity can stimulate muscle spasm and induce lumbago, which can trigger or aggravate the symptoms of lumbar disc herniation, so attention should be paid to keeping the lumbar area warm, and care should be taken to avoid catching a cold or getting cold; when working in cold and humid conditions, more attention should be paid to the rest and working posture of the lumbar area to prevent overexertion and sprain of the lumbar muscles; attention should be paid to keeping the lumbar area warm during night sleep, and a hard bed should be slept on. For surgical patients, lumbar disc removal only removes the nucleus pulposus that has been deformed and herniated or prolapsed, as well as the fibrotic nucleus pulposus within the annulus fibrosus, and the residual nucleus pulposus may be further degenerated and fibrotic after surgery, and may protrude again along the location of the foreign protrusion under the action of external force. Changes such as joint protrusion and lumbar instability may lead to recurrent attacks of back and leg pain and re-emergence of lumbar disc herniation in patients. As long as we pay attention to the correct use of the waist and careful maintenance, we can reduce the strain on the waist, delay the degeneration of the lumbar spine aging, and effectively prevent the occurrence of lumbar and leg pain symptoms.
