Wearing a medical peri-waist is an essential adjunctive treatment for lumbar disc herniation, but sometimes it is difficult to explain the use of a peri-waist to a patient in an outpatient clinic in a few words, so many doctors simply suggest it, or simply do not mention it, making such a tool for conservative treatment of lumbar herniation not play its proper role. There are many types of peri-waist, how to choose a correct peri-waist, how to wear correctly, to avoid misunderstandings hope that this small science can be helpful to lumbar disc herniation sufferers. 1, the principle of medical peri-waist treatment of lumbar disc herniation First of all, the main purpose of wearing a lumbar peri-waist for patients with lumbar disc herniation is braking, which is to limit the movement of the lumbar spine such as flexion, extension and rotation. The benefits of lumbar spine braking are: (1) to reduce the risk of aggravating the herniated disc due to lumbar spine activities; (2) to reduce the nerve irritation of the herniated disc due to lumbar spine activities; (3) to reduce muscle spasm and inflammatory irritation in the lumbar region of patients with lumbar disc herniation, to reduce the burden on the lumbar spine ligaments, and to reduce low back pain. Secondly, wearing a lumbar circumference has a certain support and weight-bearing effect. When a patient with a herniated lumbar disc stands up, the vast majority of the weight of the upper body is pressed against the herniated disc, which can aggravate the degree of protrusion, especially when moving around, the impact on the herniated disc is greater. Wearing the appropriate waist circumference, part of the upper body weight can be transferred down through the ribs – waist circumference – iliac bone, the waist circumference generated by the wrapping force and tension of the abdominal muscles can also transfer weight. In this way, the force on the lumbar vertebrae – intervertebral discs – lumbar vertebrae is greatly reduced, and to a certain extent, the pressure in the intervertebral space is relieved and improved, and the compression of the intervertebral discs on the nerve roots can be significantly relieved. Third, after wearing the waist circumference, will strengthen the strength of the abdominal muscles, reduce the lumbar vertebrae convexity, so that the center of gravity as a whole backward shift, reduce lumbar back muscle strain. Fourth, some circumference waist with magnetic therapy, infrared, heat therapy and other auxiliary functions, can help relieve lumbar back muscle spasm and inflammation of the fascia, reduce low back pain. 2, what people are suitable for wearing medical waist? Acute period of lumbar disc herniation; acute lumbar sprain; acute period of lumbar muscle strain; early period after minimally invasive or open surgery of the lumbar spine 3.How to choose the right peri-waist? (1) common waist recommendation index: ★★★★★ advantage: the length of the waist girth and the patient’s waist girth length in line, easy to use. This not only limits the movement of greater activity, but also does not affect the appropriate activities, suitable for patients with lumbar disc herniation for daily life. Disadvantages: the braking and supporting effect of the girth on the lumbar spine is relatively weak (2) lengthened girth Recommendation index: ★★★★ Advantages: the lengthened girth plays a stronger braking and supporting role, the treatment effect is exact. Disadvantages: not beautiful enough, has a certain impact on daily life. (3) inflatable waist Recommendation index: ★ Advantages: claim to have a certain traction effect after inflation. Disadvantages: the use of trouble; the amount of inflation will affect the effect of braking and support. (4) multi-functional waist Recommendation index: ★★★ Advantages: increase the magnetic therapy, infrared, heat therapy and other auxiliary functions Disadvantages: due to the need to fill the magnetic therapy, heat therapy and other built-in items, the original braking and support role is weakened. 4.How to wear the waist? How long is it appropriate to wear? When the symptoms of lumbar pain are heavy, you should wear it strictly and put it on when you get up and stand up, don’t take it off at will; for patients with light conditions, you can put it on when you go out, especially when you have to stand or sit in one position for a long time, and then take it off when you sleep and rest. The waistband should not be worn for a long time, otherwise it will lead to disuse atrophy of the muscles of the low back, weakness of the low back muscles and dependence on the waistband. Therefore, after the symptoms have gradually subsided, you should remove the waist circumference, and start to gradually resume the normal activities of the waist, and take the initiative to strengthen their own waist and back muscle exercise. Generally the entire use of time to 4 to 6 weeks is appropriate, the longest do not exceed 3 months. 5, common misconceptions about wearing a waist Myth 1, wearing a waist can safely go down to the ground activities Acute lumbar disc herniation patients with severe symptoms of lumbar pain should be bed rest, can not wear a waist belt to replace bed rest, but in the toilet or necessary activities should wear a waist belt to protect. Misconception two, 24 hours a day wearing waist some patients bed rest also wear waist circumference not relax, this practice is wrong. Lying in bed because the lumbar discs are not subject to gravity, the waist scarf will hardly play a therapeutic role, but only a psychological comfort. The 24-hour uninterrupted wearing of the waist circumference will make the lumbar muscles disuse atrophy, so that patients produce a sense of dependence, once you leave the waist circumference will appear to aggravate the symptoms of the feeling, is not conducive to the recovery of patients.
