Chronic lumbar muscle strain is a common clinical disease, belongs to the category of lumbago and paralysis in Chinese medicine, with long-term recurrent lumbar pain as the main clinical manifestation, mainly refers to the chronic injury of lumbosacral muscles, ligaments or fascia, including gluteus fascia syndrome, lumbar 3 transverse synovial syndrome, interspinous ligament injury and lumbar pain with widespread immobility but basically normal activity of cumulative lumbar muscle strain. Also known as “functional lumbago” or “lumbar back myofasciitis”, this disease has a wide range of people and is not easy to heal once suffered, and often requires long-term careful treatment to achieve satisfactory results. I. Etiology of lumbar muscle strain 1. long-term repeated lumbar muscle strain. 2.Improper treatment and improper treatment method after acute lumbar sprain. 3, long-term repeated excessive lumbar movement and excessive load, such as long periods of sitting, standing, or from the bent position to the upright position holding heavy objects, lifting objects can make the lumbar muscle in a long-term high tension state, over time can lead to chronic lumbar muscle strain. 4, chronic lumbar muscle strain and climate and environmental conditions also have a certain relationship, the temperature is too low or humidity is too large can promote or aggravate the lumbar muscle strain. Second, the lumbar muscle strain pathology waist is the midpoint of the human body, lumbosacral joint is the hub of lumbar activities, forward and backward, left and right side bending, turning are involved, whether sports or activities, the human body after getting up all the life, living and work need the support of the waist, so the muscles of the waist are prone to fatigue and injury. Some people even if physical activity is not much, labor intensity is not much, but because of the wrong posture, the spine is in a half-bent state, the back muscles have been tense, the accumulation of months also produce strain injury, further development of the formation of sterile inflammation, stimulation of nerve endings, causing pain. Frequent and repeated accumulation of minor injuries (strain) can cause pathological changes such as congestion, edema, exudation, fibrous tissue hyperplasia and adhesions in muscle attachment points, periosteum, ligaments and other tissues, which stimulate and compress nerve endings and cause low back pain. After the lesion occurs, in order to reduce the activity of the lesion, some muscles are often in spasm, and the continuous lumbar muscle spasm can also cause accumulation of soft tissue strain, further aggravating the pathological changes of the tissue, forming a vicious circle. The main symptom is pain in the lumbar or lumbosacral region, with recurrent episodes. The pain may change with climate change or the degree of exertion, sometimes light and sometimes heavy, and lingering. There may be widespread pressure pain in the lumbar region, and there is no abnormality in spinal activities. In acute attacks, all symptoms are significantly aggravated, and there may be muscle spasms, scoliosis and limitation of functional activities. Some patients may have pulling pain in the lower extremities, but there is no string pain or numbness of the skin. The nature of the pain is mostly dull and can be confined to one area or spread throughout the back. It may manifest as soreness or swelling in the lower back, with some stabbing or burning pains. The pain is aggravated by exertion, relieved by rest, relieved by proper activity and frequent changes in position, and aggravated by excessive activity. Inability to work in a stooped position. Often forced to stretch the waist or hit the waist with the fist to relieve the pain. There are pressure points in the lumbar region, mostly at the sacrospinous muscle, the posterior part of the iliac crest, the stopping point of the sacrospinous muscle or the transverse process of the lumbar vertebrae. Fourth, the treatment of chronic lumbar strain affects the normal life and work of patients, some patients seek medical help, recurrent attacks, painful, and even psychologically overshadowed, thinking that lumbar strain is incurable, in fact, lumbar strain can be completely cured, but need to pay attention to three links, 1, timely and clear diagnosis; 2, timely and effective comprehensive treatment; 3, reasonable functional exercise, good Daily health care. These three links are indispensable. The main treatment methods for lumbar muscle strain are as follows: 1. Eliminate the causes: Since chronic lumbar muscle strain generally has a long-term recurring cause of injury, the primary problem in treating chronic lumbar muscle strain is to eliminate the causes, such as improving work position and posture, and avoiding bending too long. For occupations where the waist must maintain a certain posture, the waist posture should conform to biomechanics as much as possible, and pay attention to frequent activities of the waist, do not make the waist in the same position for too long. Prevent moisture and cold from getting cold. Sleep hard bed, soft mattress can not maintain the normal physiological curvature of the spine, easy to make the waist muscle fatigue. Moderate sexual intercourse, “waist for the kidney of the house”, sexual intercourse too often is bound to damage the kidneys, kidney deficiency is waist pain. 2, drug treatment: you can choose to relax the tendons and blood, warming and dispersing the cold, dispel the wind and pass through the ligaments, the liver and benefit the kidneys of Chinese medicine, such as the only living parasitic soup, kidney and tendon soup, etc.; you can also choose to warm tendons and pass through the ligaments cream, musk tiger bone cream and other external application. In the acute stage, you can choose western medicine such as anti-inflammatory pain, futalin and other drugs for oral use, but should not be taken for a long time. 3.Manipulation therapy: on the basis of relaxing the muscles by pressing and kneading, press the painful point with force, and push, massage and roll along the sacral spine muscle from top to bottom. For adhesions or muscle tension, the technique of plucking can also be used. 4.Acupuncture and cupping treatment: for the painful point, use acupuncture and cupping such as aye-point or acupuncture point along the bladder meridian, and commission point. 5.Lumbar back muscle exercise: to increase the strength of the sacrospinous muscle muscle exercise. There are “arch bridge” and “flying swallow” and so on. 6.Other: infrared ray, ultra-short wave, wax therapy, magnetic therapy and other physical therapy methods are also available, and local closure, small needle knife and other treatment methods can be used.
