Low back pain is one of the most common symptoms of the disease. It is generally caused by muscle inflammation that occurs when the lumbar muscles are in a state of long-term incoordination due to accumulated injuries from life and work. Existing surgery and drugs can hardly achieve the effect of eliminating low back pain, because the damage to the soft tissues of the lumbar region caused by low back pain is difficult to be repaired by these means, and even if there is a little relief, it is particularly easy to recur. Overseas research has shown that through the continuous enhancement of the lumbar core muscle group movement exercises, not only can stabilize the lumbar spine, more effective prevention and treatment of low back pain. This is also the best treatment model for chronic low back pain patients, which is strongly recommended by the American National Association of Physicians. Core muscle group stability training movements are simple, no site restrictions, very suitable for the general public long-term practice. Here is a brief introduction to the four movements: ① prone support: prone position, with both elbows and feet as the fulcrum, the body will be propped up and suspended in the air, the body is a word, maintain the action for 15 seconds. ② side support: lying on your side, support your body with your elbows, take your elbows and ankles as the fulcrum, lift your body upwards into a straight line and maintain the movement for 10 seconds. ③ Double-legged bridge: supine position, flex the hip and knee, low back force, lift the low back and hip, so that the hip joints straight, can maintain the posture for 15 seconds to increase the proprioception of the low back. ④Diagonal support: take a kneeling position, support the body with both hands and knees, straighten both upper limbs, flex both hips, flex both knees at 90°, then straighten the left upper limb forward and extend the right lower limb backward, so that the body is supported only by the right hand and the left knee, maintain the posture for 10 seconds. Switch to the opposite side, same steps as before.
