The effect of lumbar disc herniation is mainly due to two reasons: 1, because after wearing the belt can effectively play a fixed role, especially inside the steel plate support belt, can effectively maintain the stability of the spinal position, to avoid violent bending and twisting waist action, can prevent the aggravation of local lumbar disc herniation, prevent the emergence of nerve root stimulation, resulting in lower limb radiating pain or numbness and other related performance. 2, after wearing the belt can play the effect of warmth, which can effectively increase the local temperature, the muscles will become more relaxed, blood circulation will also accelerate. The inflammation and lactic acid produced by local metabolites can be effectively metabolized and absorbed away, so the symptoms related to back pain can be effectively relieved. However, you can not wear a belt for a long time, because after wearing it for a long time, the human spine position is overly dependent on the belt, and muscle strength decreases, muscle atrophy, which will lead to a decrease in the stability of the spine, after taking off the waistband, it may lead to the aggravation of lumbar protrusion, or the acceleration of degenerative hyperplasia, resulting in an increasing number of symptoms.
