Lumbar girth is also called lumbar belt, lumbar girth fixed belt as a lumbar back brace, adapted to acute lumbar pain, spinal slippage, herniated disc, radicular sciatica and lumbar disorders after surgery and other clinical treatment, lumbar girth fixed belt by stabilizing the spine, limiting the lumbar and lumbosacral joint activities, assist in the treatment of lumbar disc herniation, lumbar muscle ligament injury, joint strain and other lower back pain diseases, can reduce the load on the intervertebral disc To prevent re-damage, to reduce the role of pain, but also can play a certain role in weight loss and abdominal. Long-term use of passive protection of lumbar girth can cause disuse muscle atrophy, muscle strength decline, and is not conducive to spinal stability, so wearing lumbar girth is limited to the acute phase or rehabilitation period after treatment, generally not more than 3 months, wearing lumbar girth at the same time and after the withdrawal of lumbar girth must strengthen the lumbar back muscle exercise, lumbar back muscle exercise can restore and enhance muscle strength, strengthen the stability of the spine, is an effective way to consolidate the effect of treatment, relapse prevention. Also note that when bending over to retrieve something, it is best to use a hip and knee flexion squat to reduce the pressure on the back of the intervertebral disc. A qualified lumbar girth should have several conditions: reasonable length, good support performance, proper elasticity and adaptability to the curvature of the lumbar spine. The lumbar girth should cover the position from the top to the rib arch and the bottom to the waist and hip. Waist circumference is too short, because the movement of the segment is not enough to achieve the fixed role; and too short waist circumference is also easy to wear in the process of upward displacement, losing the fixed role. But waist circumference is too long, when wearing also easy to cause discomfort. Note: 1, pay attention to the waistline elasticity. If it is too loose, it will lose its fixing effect, and if it is too tight, it will bring discomfort. Therefore, patients should wear the waist circumference according to their own feelings, in order to wear their own waist is beneficial and does not affect breathing. 2, in the treatment process of low back pain, emphasize the “combination of movement and static”, when the activity of wearing lumbar circumference can play the role of braking, support and protection, when lying down, because the spine is not under pressure, without the braking and support of the lumbar circumference protection role. At this time, you can carry out appropriate lumbar back muscle exercise, to relax muscle spasm, enhance muscle strength and improve blood circulation. 3.If local discomfort occurs, the fixation force can be reduced. 4.Pregnant women, patients with bleeding tendency, malignant tumor and skin disease are prohibited.
