The non-operative treatment of lumbar disc herniation includes: absolute bed rest, continuous traction, physical therapy, non-steroidal anti-inflammatory drugs, epidural hormone therapy, nucleus pulposus chemolysis, etc. It is the most important conservative treatment, which can replace other conservative treatments and never be PK by other conservative treatments. Absolute bed rest is the most important part of conservative treatment, which can replace other conservative treatments and can never be PK by other conservative treatments.Some statistics show that the early effects of non-surgical and surgical procedures are 87.92% and 95.78% respectively; . After two years, the results were 83.5% and 75.7% respectively. It can be seen from the long-term effect of non-surgical treatment is better, that is, the absolute bed rest effect is good. Indications] Indications for bed rest for lumbar disc herniation: (1) Young, first attack or less frequent attacks, shorter history of disease or longer history of disease but with milder symptoms and signs. It often manifests intermittent episodes, and there is a close relationship between low back and leg pain and climate change and exertion. (2) Although the symptoms are obvious, the symptoms can be relieved by themselves after resting; and those who have not undergone strict systematic conservative treatment. (3) Imaging shows that the disc herniation is small and there is no damage to the cauda equina or motor function. (4) Due to systemic diseases such as severe cardiovascular disease, diabetes mellitus, or local skin diseases can not perform surgery, or those who do not want to operate. This article only talks about absolute bed rest, the rest of the content of this website’s popular science article “talk about low back pain”. Absolute bed rest: The simplest treatment for acute lumbar disc herniation is absolute bed rest, the word absolute emphasizes that 24 hours of eating, sleeping, urinating and defecating should not get out of bed or sit up. This is usually adhered to for 3 weeks. This is the way to achieve nearly 95% good results (clinical cure). The bed is wide enough to lay mattress pads on a hard bed is appropriate. Pathophysiology] Some people have investigated and studied different positions and postures when the changes in the pressure of the intervertebral disc (upright position for 100%). The human body upright 100%; supine 25%; side lying 75%; upright 100%; sitting position 140%; forward bending 200%. In other words, the pressure of the intervertebral disc is in the lying position, the upright position, the sitting position, and the forward bending position. That is to say: lumbar disc herniation patient intervertebral disc pressure lying is less than standing, standing is less than sitting, straight sitting is less than forward bending. It can be seen that bed rest is the basis of non-surgical treatment and cannot be replaced by other methods. With the development of modern science and technology, CT/MRI has clearly shown the fate of conservative treatment of herniated nucleus pulposus. The protruding nucleus pulposus of lumbar intervertebral disc tissue can only atrophy and cannot be reset or returned. Its main performance is: through a variety of bed rest, so that the protruding nucleus pulposus eliminates edema, shrinkage, atrophy, and its surrounding tissues and nerve root edema subsides, so that the relative displacement of the nucleus pulposus and the nerve root changes, that is, the protruding nucleus pulposus does not compress the nerve root, the symptoms of low back and leg pain significantly relieved or disappeared; in the prone position, the weight of the intervertebral disc can be removed from the pressure of the body weight; the braking can reduce the muscular contraction force and the tension of all the ligaments. Braking can reduce the muscle contraction force and the ligament tension force on the intervertebral disc caused by the extrusion. The intervertebral disc is not loaded, which is conducive to the nutrient supply of the intervertebral disc and the repair of the damaged annulus fibrosus; it is conducive to the venous return around the intervertebral disc, eliminates edema and promotes the inflammation to subside; it avoids the lumbosacral nerves to move repeatedly within the vertebral canal when walking or exercising, and the irritation of the nerve root will aggravate the nerve root injury. Absolute bed rest]: Stay in bed until symptoms resolve or disappear, usually three weeks or longer. After 3 weeks of bed rest, get up and move around with a waist cuff, and do not bend over to hold objects or do more than moderate physical labor for 3 months to 6 months. Some foreign scholars have also proved that: after 4 days of bed rest, the protruding intervertebral discs can be stabilized, and there is no obvious difference with the effect of 7 days of bed rest, and the restrictive physiological activities should be started after the symptoms are obviously relieved. Functional activities help prevent myasthenia gravis. Relative bed rest]: Some patients’ symptoms do not improve despite bed rest because they are not absolutely bedridden. If the patient cannot be absolutely bedridden: the patient should try to shorten the time when leaving the bed, going down to the floor, eating, washing, urinating and defecating with a girdle. When daily activities are completed, immediately return to bed and lie flat until symptoms are relieved. This usually takes three weeks or more. If the patient wishes to change position (supine ↔ lateral) while in bed, he should turn up and down at the same time in unison, without twisting. This often requires the help and cooperation of a chaperone. The best position] Biomechanical research has proved that half Fowler position (supine will be bent at the hip and knee, under the knee pad thin pillow) or lateral position bending the knee and hip and will be a pillow pad between the legs, can significantly lift the intervertebral discs and nerve root pressure (especially lumbar 45 gap protruding); prone position is not desirable. In the acute stage of lumbar disc herniation (low back pain + leg pain and over the knee), absolute bed rest is required for 3 weeks. Functional exercises do not exist in this period. After the acute phase (3 weeks or more of absolute bed rest) the patient enters the recovery phase (1-3 months). During this period (when the symptoms of low back pain have just completely disappeared or have been significantly relieved), self-exercises can be performed in bed.
