Spinal stenosis is caused by local strain and degeneration that leads to osteophytes at the posterior edge of the vertebral body, disc herniation, thickening of the ligamentum flavum and the posterior longitudinal ligament, resulting in a decrease in the internal diameter of the spinal canal, or the presence of congenital developmental spinal stenosis, which is more likely to cause nerve compression symptoms due to acquired degenerative factors. For spinal stenosis itself, drugs and physical exercise do not play a therapeutic role, but rather aggravate the symptoms of nerve compression, especially for cervical and thoracic spinal stenosis, and the movement has the risk of forming quadriplegia. For spinal stenosis, especially in the cervical and thoracic segments, local protective braking is required, and treatment can only be done by surgery.
