The way to relieve lumbar stretching and relaxation of lumbar muscle strain: bed rest or prone position exercise movements and so on. 1. Bed rest: when lumbar pain and dysfunction are obvious, bed rest is carried out to reduce lumbar activity and load, which is conducive to tissue recovery. 2. Prone exercise movements, such as the flying swallow movement: lying on the bed, arms on both sides of the body, legs remain straight, and then the head, upper limbs and lower limbs upward; stretching prone position: with both elbows or forearms to support the pelvis and lower limbs to keep the prone position, the upper torso will be lifted up to the stretching prone position. The above actions can improve blood circulation and strengthen muscles to relieve spasm. If you are diagnosed with lumbar muscle strain, it is recommended that you go to the hospital in time and choose the right exercise for yourself under the guidance of your doctor.
