The herniated disc is not the only cause of back and leg pain, the key is the change of vertebral curvature. Because the intervertebral disc is without its own motion force, the nucleus pulposus in the intervertebral disc of the cervical and lumbar spine is stable in the middle of the vertebral body when it is newborn, and then with the formation of the lumbar curve and cervical curve, the nucleus pulposus slides to the front of the vertebral body under the vertebral body compressive stress, and space appears in the original position, and water enters to form the nucleus pulposus in a liquid-like carrier to slide with the vertebral body forward and backward. Therefore, the protrusion of the intervertebral disc in adulthood, but also under the vertebral body rotation, tilt compressive stress to protrude. Therefore, the first cause of low back pain is the displacement of the vertebral body osteoarthritis, followed by the displacement of the upper and lower vertebrae and the change of vertebral curvature. There are three main causes of low back pain: vertebral curve change, foraminal stenosis of the lateral saphenous fossa, disc herniation and secondary lumbar muscle injury. Therefore, there are four major hazards of only treating the intervertebral discs without adjusting the vertebral curvature: First, the motor function cannot be restored. Second, symptoms recur and bone and joint displacement. Third, the emergence of a variety of spinal origin diseases, such as male hypogonadism, female dysmenorrhea, chronic pelvic inflammatory disease, as well as gastrointestinal disorders, panic, chest tightness, insomnia, chronic pharyngitis, etc.. Fourthly, there is spinal stenosis, etc. Three steps in the treatment of cervical and lumbar spondylosis: Rational tendon Spinal strain disease is not a sudden trauma, but a long-term unilateral injury to a muscle group leading to misalignment of the spinal joints. Almost all clinical spinal strain disorders originate from vertebral flexural disorders. The origin of vertebral bending disorders is the imbalance of the four-dimensional muscle forces that maintain vertebral bending, so to correct the bone and adjust the bending, we must first manage the tendons. The method of tendon management mainly includes acupuncture, medicine ironing, massage, etc. Adjustment can be made through suspension traction to reset the displaced vertebrae, to achieve tendon soft bone, so that the disorder of the vertebral curve is restored or improved, satisfactory clinical results. Exercise for modern white-collar sedentary disease, we summarized the three simple exercise methods: straddle leg press, supination, chest expansion, are fully mobilize the force of the lumbar muscles in concert with the vertical spinal muscles to maintain the stability of the vertebral curve. There are also some self-exercises that can be used both for treatment and prevention. For example, hold the head flexion and extension of the cervical spine, flexion and shrugging shoulder shaking double shoulder type, chest expansion scapula back together type, two hands holding the shoulders turn chest type. These four easier to perform chest expansion exercises, adhere to the exercise for 10-20 minutes a day, can adjust the balance of thoracic back muscle force, to prevent the thoracic spine one-way scoliosis. In addition, in the daily exercise, it is recommended that more swimming, especially breaststroke and other exercises to maintain spinal balance, avoid frequent one-way sports such as badminton.
