L4/5 and L5/S1 disc herniation is the best site for lumbar disc herniation, and its incidence accounts for about 95% of all lumbar disc herniations. The human body has five lumbar vertebrae, and there is a cushion between each two lumbar vertebrae, which is composed of three parts: the nucleus pulposus, the fibrous ring, and the cartilage plate. Due to chronic strain or acute injury, the fibrous ring of the intervertebral disc ruptures and the nucleus pulposus protrudes from the fibrous ring rupture or protrudes into the spinal canal, resulting in pressure or irritation of the adjacent spinal nerve roots, resulting in lumbar pain and radiating pain to one or both lower extremities, and a series of clinical symptoms such as hyperalgesia or hypokinesia of the lower extremities. Once these diseases appear, traction exercises for the lumbar back muscles should be done in bed. For more serious patients, surgery may be required to relieve the compression of the nerve roots caused by the herniated lumbar disc.
