Physicians often require patients with acute lumbar disc herniation after a period of bed rest or traction therapy, wear a waist cuff when going down to the ground to prevent re-injury of the affected vertebrae, to further consolidate the effect of treatment. In the clinic, there are some misunderstandings about the use of waist cages, which require professional guidance from clinicians. The main role of lumbar cuff is braking and protection, as a kind of external support, the lumbar spine of the forward flexion activities have obvious limiting effect, through part of the limitation of the lumbar spine of the amount of activity and range of motion, so that the local damage tissue can rest, for the recovery of blood flow and repair of damaged tissue to create a favorable environment; at the same time has to strengthen the stability of the lumbar spine, part of the compensation for the lumbar spine due to the degeneration of the disc organization of the lumbar spine caused by the instability of the herniation of the role. The role of the lumbar spine. Whether lumbar disc herniation patients wear should be the degree of lumbar and leg pain as a criterion, acute patients with severe symptoms of lumbar and leg pain should be bed rest, can not wear a waist corset to replace the bed rest, but in the downstairs toilet activities should wear a waist corset to protect the use of pain and discomfort should be carefully adjusted the size of the waist corset, the degree of elasticity. After the acute phase, the symptoms of the relief period should begin to waist and back muscle exercise, and gradually go down to the ground activities, at this time still have to cooperate with the use of waist cuffs. Some patients bed rest also wear waist cuffs do not relax, this practice is wrong, because long-term wear waist cuffs will make the lumbar muscles to varying degrees of wasting atrophy, so that the patient to produce a sense of dependence, once you leave the waist cuffs will appear to exacerbate the feeling of symptoms, is not conducive to the recovery of the patient. Wearing a waist cuff is only a temporary, excessive auxiliary treatment measures, in the selection of waist cuffs can be first wide and then narrow, first hard and then soft, and gradually shorten the use of time wearing a waist cuff, in the wearing method can be first tight and then loose, and gradually get rid of the dependence on the waist cuffs, through the moderate lumbar and dorsal muscle function exercise, and gradually achieve the goal of complete recovery.
