Patients with lumbar muscle strain and lumbar disc herniation can use lumbar belts. The use of lumbar belt when lumbar muscle strain can exert certain pressure on the lumbar muscles, which helps to maintain the balance of the force on the lumbar movement, thus reducing the force on the lumbar area. And the lumbar belt can strengthen the muscle strength to a certain extent, promote the swelling of the lumbar muscles to subside and reduce the excessive stimulation of the lumbar muscles in the process of movement, thus reducing the clinical symptoms of lumbar muscle strain. The use of lumbar disc herniation belt can play a protective and supportive role for the waist, but it is not recommended to use lumbar belt fixation all the time, because the use of lumbar belt for too long will weaken the strength of the lumbar back muscle, so that the lumbar muscle support force is weakened, which is not conducive to the rehabilitation of patients with lumbar disc herniation. Usually not recommended to wear, only when carrying things or need to do waist force action, can form a protection for the lumbar disc.
