What you need to know about waist support

- Dec 13, 2019-

Lumbar support occupies a relatively important position in the clinical practice of spinal surgery. For most spinal diseases, one of the main methods of conservative treatment is lumbar support. However, in the clinic, patients often complained that the lumbar support belt was useless. Ask him what lumbar support he took, and take a closer look at the removed items. Except that the shape can be called waist support, the inner root of the inner body cannot fit on the lumbar support... Many doctors have limited knowledge of the lumbar support. Today we will talk about the lumbar support.


What is the cause of low back pain?

The cause of low back pain is very complicated, so complicated that it can write a book, obviously, this is not the focus of this article. The mechanisms of pain generation are generally summarized into three categories:


The first type of pain comes from bony structures, such as spinal instability and spinal fractures;


The second type of pain is caused by damage to soft tissues, such as paraspinal muscles;


The third type of pain comes from nerves, such as pain caused by herniated discs.


In many cases, the three categories of pain are not as distinguished as detailed, and to a certain extent, they will affect each other and cause each other.



What is the mechanism of the lumbar support?

The above summarizes the causes of low back pain. At this stage, all conservative or surgical treatment plans for low back pain are actually based on these three aspects. The existence of waist support as an external form of external fixation bracket similar to trauma orthopedics, the main functions are:


1. Protect the waist muscles and relax the waist muscles. When the human body stands daily, there is a certain tension in the spinal muscles of the lower back to maintain the human body's upright posture. The pain in the waist will fix the spine in a pain-free position and eventually lead to the waist. Muscle spasms, which in turn will aggravate low back pain and form a vicious circle. After wearing waist support, it can partially replace the back muscles to maintain the posture of the human body, improve the stress status of the back muscles, relax the muscles, and reduce back pain;


2. Restrict the movement of the spine. The unstable movement of the spine is a major cause of low back pain. Wearing a lumbar support can largely limit the movement of the waist. After the activity is reduced, local repair of the spinal injury can relieve pain.


Does the waist support work?

Whether the lumbar support is effective or not, many patients in the clinic will have questions about this problem. According to the existing literature, for patients with acute low back pain, the effect of wearing lumbar support to treat low back pain is relatively certain. Calmels, Pope, and others have reported this. For the previous medical history of low back pain, use lumbar support for low back pain. The effect of prevention has also been affirmed, and the literature reports of Roelofs, Jellema, and others have confirmed this; but the effect of brace treatment for patients with chronic low back pain is unclear, and the current literature does not support the use of lumbar support for this type of population. For treatment.


The reason why the treatment effects of acute and chronic low back pain braces are not clear is unclear. The personal analysis shows that acute low back pain is related to acute damage to the body structure. Wearing waist support provides a relatively good healing environment for acute injuries, and natural back pain after structural healing Relieve; for chronic low back pain, the damaged structure undergoes the process of injury-repair. This process has become chronic. The short-term wearing of the waist support does not fundamentally solve the dynamic evolution process of injury-repair.


How to bring the waist support?

After choosing the right lumbar support, you need to pay attention to wearing it properly. I generally require patients to wear a lumbar support when they wake up but do not need to wear waist support when sleeping in bed. It should be noted that many patients with low back pain, in order to save trouble, get up from the bed and then bring waist support, which is actually not the most appropriate method. The correct method is: wear waist support on the bed, and then sit up with the upper limbs on one side. It should be emphasized that after wearing the lumbar support, it is necessary to ensure that three-point support can be completed. Too-Short lumbar support has no effect.


How long is the waistband suitable?

There is currently no unified opinion on the time of wearing waist support. It is mainly based on specific conditions. Different diseases have different requirements for wearing waist support. Generally, it is recommended to wear it for about 3 months, and the maximum time is not more than 6 months. As a treatment measure, the lumbar support is prone to weaken the core muscle group and restrict spine movement. If it is worn for a long time, it is not recommended as a long-term treatment option.


We often see acute low back pain in everyday life, which is often referred to as "flash to the waist". The North American Spine Association had relatively clear recommendations in 2005 [6]. Months), the lumbar support was applied within a short time (1 to 3 weeks), and the treatment effect was relatively accurate.
