The general principles of lumbar self-care for patients with low back pain are: 1) maintain a normal spinal curve; 2) plan in advance before exercise; 3) use some help if necessary; 4) avoid maintaining the same position for a long time; 5) maintain a wide, stable base support surface when in a standing or sitting position; 6) when turning the body, rotate on the axis of the feet, not rotate the waist; 7) when lifting objects or carrying out daily activities, keep the abdominal muscles tense; 8) when carrying objects, keep them close to the body; 9) when lifting objects from the ground, bend both lower limbs and avoid bending the waist or perform daily activities, keep the abdominal muscles tense; 8, when carrying objects, should keep the object close to the body; 9, when lifting objects from the ground, should bend both lower limbs, avoid bending; (1) lying position: lying rest or sleep, the back should also be maintained in a balanced position. The mattress must be placed on a solid bed frame to avoid sagging. A pillow can be placed under the knee in the supine position; a pillow is placed between the legs in the lateral position, with the leg located below slightly straightened and the leg above flexed. In the bed and out of bed transfer activities, should try to avoid the rotation of the waist and bending movements. (2) Sitting position: the lumbar back should be well supported in the sitting position to maintain the normal lumbar protrusion. It is best to use a chair with armrests, which is suitable for patients with more severe symptoms. The appropriate height of the chair is: when sitting or standing, the angle between the knee and the hip joint should be slightly less than or equal to 90 °. If the chair is too high, it should be replaced by a short chair or a support under the soles of the feet. (3) Standing/walking: When standing, attention should be paid to posture maintenance and maintaining the balance of the spine. Many patients will experience increased symptoms of lumbar and leg pain after long hours of standing, thus in order to relieve symptoms, for people who work long hours standing, they can put one foot on a step or stool of about 10-20 cm height or lean the back of their body on a support, which can effectively reduce the anterior protrusion of the lumbar spine. Patients are advised to walk at a brisk pace, which can often reduce the symptoms of lumbar pain. Since wearing high-heeled shoes can increase the anterior lumbar protrusion, some patients may experience increased symptoms, so choose shoes that provide maximum comfort for the feet and low back. (4) Bending/carrying heavy objects: For patients with lumbar disc herniation, post-operative lumbar spine, bending can aggravate symptoms or a history of chronic low back pain, they should learn how to bend properly. For patients with lumbar spine pathology, the normal lumbar curve can be maintained by flexing the knee and hip joints, thus avoiding excessive stress on the lumbar region. If necessary, get used to this type of bending by wearing a hard girth for a period of time. It is important to master the correct way to carry heavy objects. When lifting or carrying heavy objects, the patient should bend the knees and hips and bring the object as close to the body as possible. When bending from the knee to lift objects, the stress on the lumbar region is great due to the increase of the resistance arm, and it is easy to be injured.
