First, pay attention to low back muscle exercise Low back pain is a common complaint of orthopedic outpatients. After a good visit, the doctor will often ask the patient to do low back exercises. Why is the exercise of the lumbar back muscle important? The lumbar back muscle is one of the important structures to maintain the stability of the lumbar spine. Strengthening the exercise of the lumbar back muscle helps to maintain and enhance the stability of the lumbar spine, thus delaying the process of lumbar strain degeneration and effectively preventing the occurrence of acute and chronic lumbar injuries and low back pain. This is especially important for patients who have had acute and chronic lumbar muscle injuries, lumbar myofasciitis, lumbar strain or lumbar disc herniation and are currently in remission to prevent recurrence of the condition. People who are resting in bed or wearing a lumbar brace for treatment due to lumbar pain, the lumbar region is inactive and unstressed, which can cause disuse atrophy and weakness of the lumbar muscles in the long run, therefore, the exercise of the lumbar back muscles should be strengthened more. The method of lumbar back muscle exercise is simple, easy and inexpensive, and everyone can do it by themselves every day. Basically, there are no adverse effects of various other treatments. Second, the method 1, five-point support method supine in bed, to pillow bending knees, double elbows and head against the bed, abdomen and hips up, relying on the head, double elbows and feet the five points to support the weight of the whole body (Figure 1 above), for 3 to 5 seconds, and then relax the lumbar muscles, put down the hips to rest for 3 to 5 seconds for an action, 20 actions for a group, do 3 groups at a time, do 2 to 3 times a day. 2, three-point support method supine on the bed, with the head, feet the three points to support the weight of the whole body (Figure 2 above), the specific method as above. 3, four-point support method supine on the bed, with hands, feet, the four points to support the weight of the entire body (Figure 3), the specific method as above. 4, swallow style this action because of the flying swallows commonly known as “swallow fly” or “small swallow fly”. Prone on the bed, go to the pillow, hands behind the back, lift the head with force, so that the head and chest out of the bed, while the knees straight, the two thighs force backward also leave the bed, (Figure 6), exercise the early lumbar and back muscles strength is poor can be carried out to lift the head and back to extend the lower limbs alternately (Figure 4, 5), the specific method as above. 5, backward walking backward walking is currently a more internationally implemented exercise therapy for the treatment of lumbar spine disease. Backward walking alternate legs backward step, a walk of 30 to 60 minutes is appropriate, 1 to 2 times a day. Third, precautions 1, for the lumbar muscle strength is weak or obese people, “Xiaoyanfei” may be more laborious, you can use the “five-point support” method of exercise. Patients can choose the appropriate method for their own exercise according to their actual situation. 2, the number and intensity of lumbar back muscle exercise should be different from person to person, more than ten times a day to more than a hundred times, in 3 to 5 groups to complete.
