Concept and causes of lumbar strain injury Concept: Lumbar strain injury refers to chronic injury of soft tissues such as lumbar muscles, fascia and ligaments. Causes: (1), after acute lumbar sprain and long-term repeated lumbar strain. (2), untimely treatment and improper treatment methods. (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, 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 Diagnostic points of lumbar strain Symptoms: patients mostly have a history of lumbar overwork or different degrees of trauma. Low back pain, sometimes light and sometimes heavy, recurring, aggravated by exertion, reduced after rest, difficulty in bending over, pain aggravated by bending over for a long time, often like to pound the waist with both hands to relieve pain. A few patients have pain that increases at night after sleeping and decreases or disappears after getting up and moving around. Signs: There is no abnormality in the appearance of the lumbar region, and there is no obstacle in the tilting activities. In a few patients, the lumbar movement is slightly restricted and there is pressure pain, and the pressure pain is mostly at the sacrospinous muscle, the stop of sacrospinous muscle behind the sacrum, or the posterior part of the iliac crest or the transverse process of the lumbar spine. Auxiliary examinations: X-rays are mostly unremarkable, but a few patients may have osteophytes or spinal deformities. How should lumbar strain be treated? Avoid overwork, humidity and cold, and correct poor body position. Appropriate functional exercise: This is the method of self-help, and the disease depends on oneself to a certain extent. Such as morning and evening “swallow” lumbar back muscle exercise: prone position, with the abdomen as the fulcrum, limbs and neck backward extension, adhere to 30 seconds (according to their own endurance adjustment), rest about 10 seconds (no requirements, can set their own), for a complete action, repeated 5 times, morning and evening, persistently, in order to strengthen the lumbar muscle, ligaments. Correct the posterior lumbar joint disorder. In case of heavy symptoms, physiotherapy, massage, acupuncture, medicine, closure, etc. Drug therapy: mainly non-steroidal anti-inflammatory and pain-relieving drugs and tendon-relieving and blood-activating drugs Closure therapy: for those with fixed pressure points, 1-2% lidocaine 5-10ml plus prednisolone acetate or hydrocortisone 0.5-1ml can be used for pain point closure How should lumbar strain injury be prevented? Lumbar strain injury is mainly due to injury or long-term incorrect posture during labor, study and work, which makes the lumbar muscle overworked and causes chronic injury, such as often carrying heavy objects, working and studying while lying on the table for a long time, sitting for a long time, etc. The lumbar muscle is under long-term tension and overworked and causes chronic injury. So usually should pay attention to maintain the correct posture, heavy physical labor or exercise should do a good job of protection. ①, first of all, to strengthen the exercise: sitting people for years, the lumbar back muscles are weak, easy to damage Therefore, should be purposeful to strengthen the exercise of the lumbar back muscles, such as doing some back stretching left and right lumbar side-bending rotation movements, morning and evening at home can be “swallow” lumbar back muscle exercise, so that the lumbar muscles developed and strong, strong ligaments, flexible joints, to reduce the The chance of disease. ②, obese people should lose weight to reduce the burden of the waist,. ③, pay attention to self-regulation, work and rest, to avoid long-term fixed in a movement and mandatory bending action ④, pay attention to various postures in life, such as extracting heavy objects from the ground, should be bent knees squatting, to avoid bending back to increase the burden; take heavy objects, the body as close as possible to the object, and make it close to the abdomen, legs slightly squatting; to a high place to pick up and put things, can not reach should not be forced; sleep should keep the spine bend, etc. ⑤, avoid moisture and cold
