Lumbar spinal stenosis is one of the common causes of low back pain or low back pain, mostly seen in middle-aged and elderly people. It is actually a group of chronic progressive spinal cord and spinal nerve root disorders. Usually, lumbar spinal stenosis consists of three parts, i.e., the main spinal canal, the neural spinal canal, and intervertebral foraminal stenosis. Lumbar spinal stenosis occurs when various causes of osteophytes or fibrous tissue proliferation and hypertrophy lead to narrowing of the lumbar spinal canal or nerve roots or intervertebral foramina, resulting in compression of the cauda equina or the nerve roots and symptoms. The two qualifiers of chronic and progressive here point out the characteristics of the natural history of lumbar spinal stenosis, and are two points we need to pay attention to: 1. Chronic Lumbar spinal stenosis is a chronic disease, which accumulates year by year, and long-term incorrect postures and less and less exercise all lead to more and more pressure on the cervical spine. Therefore, the protection of spinal health should start at a young age. At the same time, we should be told that the treatment of this disease is a long-term process, especially lifestyle intervention. 2.Progressive Progressive refers to the lumbar spinal stenosis will gradually aggravate, once the spinal stenosis reaches a certain level, the body’s compensatory capacity reaches the limit, then there will be obvious clinical symptoms, at this time conservative treatment will be difficult to succeed, need to consider surgical treatment. Doctors suggest that usual focus on lumbar exercise, pay attention to living and avoiding wind, cold, humidity, appropriate sports, etc., can help prevent the occurrence of lumbar spinal stenosis. If lumbar spinal stenosis has already occurred, patients should actively seek medical treatment.
