The purpose of wearing lumbar braces for patients with lumbar disc herniation is to reduce the load on the lumbar spine and to brake it. The pathological change of lumbar disc herniation is that the protruding disc compresses the nerve root, and the nerve root undergoes inflammation and edema and produces a series of symptoms. Since the lumbar spine bears most of the weight of the upper body when a person is standing upright, in the force structure of the lumbar spine, the small joints of the lumbar spine bear a small portion of the weight, and the most important is still the vertebral body – intervertebral disc – vertebral body. If a patient with a herniated disc has to stand up, the majority of the weight of the upper body is pressed on the herniated disc, which can aggravate the degree of herniation, especially when the activity, the impact on the herniated disc is even greater. Wearing a proper waist corset can transfer part of the weight of the upper body through the ribs – waist corset – iliac bone, the waist corset produces wrapping force tension abdominal muscles, can also transfer the weight. In this way, the lumbar vertebrae – intervertebral disc – lumbar spine of the force is greatly reduced, the intervertebral disc on the nerve root of the compression can be significantly alleviated, in favor of the intervertebral disc of the return and the nerve root inflammation, edema absorption. Another role of lumbar cuff is braking, that is, limiting the activities of lumbar vertebrae, especially limiting the activities of lumbar vertebrae such as forward flexion and lateral flexion, reducing the stimulation of intervertebral discs and alleviating the stress of lumbar muscle groups, so as to create the conditions for the early recovery of the organism. Lumbar circumference is an essential adjunctive treatment for lumbar disc herniation, and there are requirements for its size, hardness and material. Lumbar disc herniation patients use waist cushion, generally choose leather or artificial leather made of leather, the length of the waist cushion and the patient’s waist length in line with the width in the middle, that is, the lumbar vertebrae to be wider in the middle of about 20. m. In the middle of about 30cm long position, that is, the lumbar vertebrae back, built-in 4-6 pieces of 20cm long, 2m wide, steel or bamboo plate vertical support. The two ends, that is, between the coercive ribs and the anterior (posterior) upper iliac spine and the abdominal position, with a width of 10-15cm, can be slightly softer, and the whole waist circumference outside the bundle of an ordinary belt reinforcement, which can make the patient easy to use. This not only restricts the movement of greater mobility, but also does not affect the patient’s appropriate activities, suitable for lumbar disc herniation patients to carry out daily work, walking, traveling, etc.. Lumbar perimeter in the treatment of lumbar disc herniation in the process of the use of a wider range, but wear and use is not arbitrary, should pay attention to the following issues: lumbar perimeter wear and use should be flexible according to the condition. After the patient has been vigorously traction or long-term bed-ridden treatment, the patient should strictly follow the doctor’s instructions to wear a waist cuff on the ground to consolidate the therapeutic effect. When the condition is reduced, the symptoms disappear, 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 vertebrae support and protection role. Otherwise, long-term unprincipled wear waist corset will make the lumbar back muscle disuse atrophy and joint ankylosis, the patient will not be able to get away from the waist corset, otherwise the symptoms worsen the phenomenon, which is harmful to the treatment of lumbar disc herniation. The specification of waist cinching should be adapted to the patient’s body type, generally up to the lower rib arch, down to the iliac crest, the back side should not be too convex, and the front side should not be tied too tightly, and good physiological curvature of the lumbar vertebrae should be maintained. If the specification of the waist cuff is not appropriate, not only will the patient feel uncomfortable after wearing it, but also can not play its proper role.
