Acute lumbar sprain is a condition in which the waist is injured by sudden violence or uncoordinated movement, resulting in lumbar muscle injury and small joint disorder, and lumbar pain and functional limitation. 1. Diagnosis 1.1 Clinical manifestations 1.1.1 Symptoms: In more serious cases, severe pain in the lumbar region after the injury, inconvenience in movement, difficulty in sitting, lying down, turning over, or even inability to get up, and the pain increases when coughing or deep breathing. In some patients, the pain is not severe when the back is twisted or flashed, and they can continue to work, and the back pain only gradually increases after a few hours or 1-2 days. 1.1.2 Signs 1.1.2.1 Pressure pain: In the early stage of sprain, most patients have obvious limited pressure pain points. Generally, the pressure pain point is the site of injury. 1.1.2.2 Muscle spasm: mainly occurs in the sacrospinous and gluteus maximus muscles. It is a protective response to pain and can be unilateral or bilateral. These muscles have pressure pain due to increased tension, which is slightly relieved when lying down, but the spasm reappears when pressing with the fingers. 1.1.2.3 Alteration of the physiological curve of the spine: pain can cause protective muscle spasm, but asymmetric muscle spasm can cause alteration of the physiological curve of the spine. The lumbar spine tilts more to the affected side. 1.1.2.4 Lumbar mobility function: all have different degrees of impairment. 1.2 Diagnostic criteria 1.2.1 History of obvious sprain. 1.2.2 There is obvious local pressure pain and palpable change of local muscle tension 1.2.3 Restriction of lumbar activity function. 2. Identification The disease all occurs due to injury, twisting and pulling. 3. Treatment 3.1 Principle of treatment: relaxing tendons and channels, activating blood circulation and relieving pain, and rehabilitating joints. 3.2 Techniques: rolling, kneading, pointing, pressing, holding, rubbing, plucking and wrenching. 3.3 Acupuncture points: kidney, lumbar eye, central committee and local adjacent acupuncture points. 3.4 Operation: patient in prone position. Use the rolling method to treat around the pressure point and gradually move to the painful area, with light to heavy pressure, repeatedly for 5 minutes, together with passive activities of lumbar back extension, with small to large amplitude. Press and knead Kidney Yu and Lumbar Eye, and take the Wei Zhong, to the extent of soreness and swelling. Then use the tendon splitting method and tendon plucking method to treat above and below the painful point, the technique should be soft and deep. If the spine is distorted, the joint can be repaired by rotational repositioning method. Finally, use palm pushing method to operate on the injured side from top to bottom for 3 – 5 times, and then use direct rubbing method to operate to the extent of heat penetration. 3.5 . Other therapies 3.5.1 Physiotherapy: can relieve muscle tension and relieve pain. 3.5.2 Drug patch: commonly used are dog skin paste, Qizheng pain relief patch, Doc’s self-heating patch, blood-vitalizing bone patch, etc. 3.5.3 Acupuncture and moxibustion therapy: it has good curative effect, and it works better with Tui Na. Massage is effective for this disease, generally can be cured by 1 – 2 times treatment. If accompanied by joint disorders or touch a spine has a skewed, try to adjust these joints to a normal position. This can achieve the fundamental treatment.
