Low back pain is a common symptom, and acute and chronic lumbar strain is its main cause. Some people like to receive massage, physical therapy, heat and other treatment methods, and some long-term wear a brace. In fact, this is very incomplete, but only a passive method of treating low back pain. Because for acute lumbar sprain, in the acute period (within 3 weeks) can be lying down to rest, walking wearing a brace treatment, acute period should be carried out after the lumbar and dorsal muscle function exercise. Chronic lumbar muscle strain patients, massage, physical therapy, hot packs can indeed reduce pain, improve symptoms, but this is only one aspect. Because lumbar muscle strain is accompanied by lumbar back muscle atrophy, weakness, and lumbar back muscle weakness is caused by low back pain factors, so lumbar back muscle function exercise is the main means of treatment. How to carry out functional exercises for low back muscles? Middle-aged and elderly people often have weak abdominal muscles and low back muscles, manifested as “general belly”, so it should be exercised at the same time abdominal muscles and low back muscles. Specific practices are as follows: 1, take the prone position, upper limbs on both sides of the body or back hand posture. Head and neck back up, while both lower limbs straighten and try to lift, so that it leaves the bed, shaped like a “swallow fly” shape. 2, lying position, do sit-ups. If you can not complete this action, you should also lie down, hold your head with both hands, do sit-up action, the purpose is to practice the abdominal muscles. Functional exercise intensity should be from small to large, can be tolerated to the extent. In addition, you can also do moderate flexion and extension activities in conjunction with your physical condition, and try to walk with your chest lifted. If you can insist on doing the above functional exercises, you can not only treat the lumbar pain caused by lumbar muscle strain, but also prevent the occurrence of osteoporosis and reduce the senile hunchback.
