The vast majority of patients who have suffered from a herniated disc will wear a lumbar support on the advice of their doctor. The lumbar support has 2 roles: firstly, it is a braking effect. The lumbar support is usually made of leather or canvas lined with steel or bamboo pieces, which reaches the rib cage above and covers the iliac bone below, and is tightened in front. Therefore, when wearing a lumbar support, the activities of the waist, especially bending will play a limiting role, so that the lower back muscles can get relatively adequate rest, relieve muscle spasm, promote the recovery of blood circulation, so that the muscle inside the pain-causing substances quickly dissipate, so that the inflammatory reaction around the nerve roots and lumbar joints to reduce or disappear. The second is the protective effect, because the lumbar protector can strengthen the stability of the lumbar region, so when patients with lumbar disc herniation start to move on the ground after bed or traction treatment, they often wear a lumbar protector to strengthen the protection, so that the amount of activity and the range of activity of the lumbar spine is somewhat limited to consolidate the effect of the previous treatment. Therefore, whether a patient with a herniated lumbar disc chooses to rest in bed or receive physical therapy, it is essential that the patient wears a lumbar support to treat and relieve the condition and reduce recurrence. When wearing a lumbar support, the patient will have a sense of lumbar relaxation and dependence is the direct reason why the patient chooses to wear a lumbar support. Because the patient will have a sense of dependence after wearing the lumbar support, so we encountered some patients wearing the lumbar support for a long time, unwilling to actively remove the lumbar support, they are used to wearing the lumbar support life, work outside. The use of lumbar support or lumbar brace has both advantages and disadvantages. The advantage is that it is reliable for the relief of symptoms, but the disadvantage is that it weakens the opportunity to exercise the lumbar muscles, and long-term application can cause atrophy of the lumbar muscles and stiffness of the lumbar region. So the wearing time should not be too long, when the symptoms are serious may wish to apply a short time, in the symptoms should be gradually reduced after the timely removal. Other times if there is no discomfort, it is not necessary to wear often, should let the lumbar muscles have appropriate exercise opportunities as appropriate. During the application of lumbar protection, to strengthen the exercise of the lumbar back muscles, in order to restore its strength, conducive to the recovery and strengthening of lumbar spine stability.
