Lumbar back strain is a chronic injury in which the lumbar muscles and ligaments are frequently and repeatedly strained or under constant tension, resulting in microscopic changes in their tissue structure and gradual accumulation, or in which the acute lumbar sprain is not treated promptly and effectively and becomes chronic. Causes and principles of lumbar back strain The most common cause is long-term excessive weight bearing or long-term poor posture of the waist, so that the lumbar muscles and ligaments are under persistent tension. This long-term accumulative strain leads to muscle ligament tissue ischemia and metabolic disorders as well as chronic tissue damage and inflammatory reactions, resulting in persistent lumbar pain that is difficult to heal. After an acute sprain of the lumbar region, the local muscles, ligaments and other tissues are damaged, not even if treated or improperly treated, the injury fails to recover and is delayed into a chronic injury. Lumbar muscle strain and lumbar disc herniation can be identified by whether there is leg pain, whether the pressure point is in the middle or on both sides, whether the activity is limited and imaging examination. Symptoms Pain or swelling in the lumbar region, sometimes difficult to bend over, pain increases when bending over for a long time, relieved after rest, and can be relieved after appropriate activities or frequent position changes. Sitting or lying down with a small pillow on the waist can reduce the symptoms, often like to pound the waist with two hands, as well as self-pressing the two lumbar eyes to feel comfortable. Rehabilitation Lumbar muscle strain can be rehabilitated through massage, physical therapy, physiotherapy and other methods, here we mainly talk about the methods of physical therapy, that is, by strengthening the lumbar and abdominal muscle strength and stretching exercise, increase muscle flexibility and endurance, improve the stability of the spine, flexibility, and release the local tissue adhesions. Many people only pay attention to the strength of the erector spinae or abdominal muscles, but only when the strength of both is properly balanced, can maintain good body posture and lumbar spine stability. Examples of exercise methods: The following methods are effective in improving the strength of the lumbar and abdominal muscles, each action can be done 4X8 beats at a time. Practice 1 time each day in the morning and evening. Prone extension; prone leg extension; prone swallow extension; supine knee hold; supine hip lift; supine half bridge; supine sit-up; local acupuncture, physiotherapy, cupping, traction, etc., will help to relieve lumbar back muscle strain. Prevention People who are engaged in static work of the lumbar region should often insist on doing lumbar and abdominal exercises to strengthen the strength of the lumbar muscles. Waist load should be properly controlled when fatigue is not eliminated. After each sports training must do lumbar muscle stretching action to relax the tense muscles.
