The key to treating lumbar muscle strain is to exercise the muscles of the lower back. The most recommended methods for exercising the muscles of the lower back include: 1, swimming: swimming is the exercise of the muscles of the lower back without weight, which is not only suitable for lumbar muscle strain, but also for lumbar disc herniation and lumbar degeneration and other lumbar disorders. 2, “flying swallow” lumbar back muscle exercise method. Take a prone position, go to the pillow, and then lift the chest with force, hands and feet to the air, as if the swallow is flying. Exercise, a single lifting action to last 3-5 seconds, then relax the muscles, rest 3-5 seconds, this is a cycle. Exercise once a day in the morning and evening, each time to do 20-30 cycles, long-term persistence, can play a good relief effect.

This method is also beneficial for people who feel discomfort in the neck muscles. In addition, massage is also an effective method. In addition to exercise, the use of appropriate physical therapy under the guidance of a doctor can also enhance the effectiveness of treatment. There are more physical therapy modalities, including electromagnetic, ultrasonic, infrared, laser, etc., which act on the body through sound, light, electricity, heat, etc., and play a role in unblocking and activating the muscles.
