Once the lumbar muscle strain is difficult to cure. Because lumbar muscle strain itself is a chronic inflammatory disease. It is defined as a chronic, damaging inflammation of the muscles of the lower back, their attachment points, the fascia, and even the periosteum, and is one of the most common causes of low back pain. The formation of lumbar muscle strain is mainly due to two reasons, the first is the acute lumbar trauma treatment is not appropriate, and finally become chronic strain; Second, is the lumbar muscle groups in the base of instability, overloaded exercise, and finally lead to compensatory hyperplasia hypertrophy, and insufficient blood supply and oxygen supply, and their own waste, not out, and finally stimulate the formation of a local injury. Therefore, according to the etiology, there is no cure for lumbar muscle strain injury, because it is not an overnight process, but a long-term chronic and repeated stimulation, and finally formed, even if the inflammation is controlled, there is no way to make the compensatory muscles back to the previous condition. So at present for the lumbar muscle strain, there is no cure, basically symptomatic treatment, and do the appropriate strengthening of the lumbar back muscle strength and functional training, mainly prevention-oriented, and then add the appropriate treatment, so the lumbar muscle strain once the formation of it is very difficult to cure.
