Narrowing of the intervertebral space is irreversible and cannot be reversed. Narrowing of the intervertebral space is often accompanied by significant narrowing of the intervertebral space on x-ray radiographs. Patients may also experience a herniated disc on CT or MRI of the lumbar spine. The herniated disc is often caused by degeneration of the intervertebral disc or a decrease in the nutritional status of the intervertebral disc, which develops into a herniated disc at a later stage, and the narrowing of the intervertebral space at a later stage, which is irreversible. In the clinic, if there is obvious narrowing of the intervertebral space during the radiographic examination, it is possible to alleviate the development of the disease through the later maintenance and treatment. For this kind of patients, they can exercise through the rehabilitation function, such as the small swallow exercise, pulling the bar, and exercising the strength of the lumbar and back muscles, and through the exercise, the lumbar and back muscles can be strengthened, which can alleviate the pressure of the vertebrae on the weight of the human body. Usually sleep on a hard board bed, minimize bending over to do heavy work, through this way is completely can shorten its course, once the intervertebral space narrowing recovery is impossible.
