Many patients with lumbar disorders, such as lumbar disc herniation and lumbar spine fracture, will have the experience of wearing a waist cuff under the guidance of a doctor or purchasing one on their own. Waist cuffs can relieve pain and prevent further aggravation of the disease, and have indeed achieved a certain therapeutic effect in the clinic. However, some patients take the waist cuff as a cure for all diseases of the magic weapon, the waist of the slightest discomfort to wear, do not dare to move, thinking that it can stop the pain, cure the disease. Do not know, long-term do not only can not play a role in curing diseases, and on the waist muscles, spine has a great role in injury. Waist is commonly used in orthopedics in a support, generally made of leather or canvas (sometimes lined with steel), in China more than a thousand years ago in ancient times, there are bamboo wrapped around the waist to treat lumbar vertebrae fracture and dislocation of the experience. The main role of the lumbar girdle, to put it bluntly, is to brake and protect the lumbar vertebrae and muscle ligaments. (1) Braking effect. When worn, the upper part reaches the lower rib arch, the lower part covers the iliac crest, and the anterior part is tightened. Therefore, when wearing a lumbar girdle, the activities of the lumbar spine, especially forward flexion activities will play a role in limiting the lumbar spine, so that the local lumbar spine tissues can get relatively full rest, relieve muscle spasm, so that the damage to the bones, muscles, soft tissues and other soft tissues to have a certain amount of time to repair, dissipate and reduce the release of inflammatory pain-causing substances, so that inflammatory reactions around the nerve root and intervertebral joints can be reduced or disappeared. (2) Protective effect. Because the lumbar region supports the weight of the upper body and has to cooperate with various activities of the human body, it is easy to be injured. The structure of the waist is mainly composed of the lumbar spine and muscle ligaments, this structure makes the lumbar activities flexible but easy to be injured, waist cushion makes the spinal muscles and so on into a whole, can strengthen the stability of the lumbar vertebrae, reduce the amount of lumbar activities. The use of waist circumference is wider, but its wear and use is not arbitrary, should pay attention to according to the condition of flexibility. In the lumbar acute period should be strictly bed rest, strengthen their own lumbar back muscle exercise, do not have to wear a waist cuff; and when by vigorous traction or long-term bed treatment, the condition is reduced, pain relief, should strictly comply with the doctor’s instructions to wear a waist cuff down to consolidate the therapeutic effect. If the pain still exists, you should have the courage and confidence to overcome the disease and get out of bed under the protection of waist circumference, and you should know that it is unrealistic to exercise completely without pain. At the same time, should not produce a sense of dependence on the waist cushion, should be removed in a timely manner, to strengthen their own lumbar back muscle exercise, in order to strengthen their own muscle strength to the lumbar spine of the support and protection role. Otherwise, long-term unprincipled wear waist corset will make the lumbar back muscle atrophy and joint ankylosis, the patient will appear a remove the waist corset, feel the waist as if there is no support, there is a “loose” feeling.
