“You don’t stand and talk without pain”, when a person does not put himself in other people’s shoes, but only cares about his own tall talk or gloomy comments about others, often this sentence will be unkindly interrupted. This is not a nice phrase here, but when explaining lumbar disc herniation, this phrase is a real truth, a scientific truth that has been carefully summarized by the old ancestors after thousands of years of observation. Standing and talking without back pain is relative to sitting and talking. This is in fact discussing the issue of the size of the pressure on the lumbar intervertebral discs under the two positions of standing and sitting. The muscles on both sides of the spine are equivalent to two springs that contract to form an inward pressure that acts on each intervertebral disc, causing it to have a tendency to expand around, while humans are different from their vertebrate counterparts and are upright walking animals, the intervertebral discs have to withstand the spring pressure of the muscles on both sides in addition to the pressure from the upper body weight, so humans are more prone to lumbar disc herniation than animals walking on all fours, and even It can be said that lumbar disc herniation is a disease unique to humans. When the abdomen is contracted and tense in the standing position, it can bear part of the upper body weight, while in the sitting position, the abdomen is relaxed and basically does not share the upper body weight, so that the upper body weight is completely borne by the intervertebral disc, so the pressure brought by the weight of the intervertebral disc is less in the standing position than in the sitting position; the muscles on both sides of the spine are moderately contracted when standing, while the muscles are heavily contracted in the sitting position, so the muscle spring pressure borne by the intervertebral disc is also smaller in the standing position than in the sitting position. is smaller than that in sitting position. Therefore, the pressure on the intervertebral disc in the sitting position is high, and the pressure on the outward protrusion is also high, leading to increased symptoms and obvious pain, while the pressure on the intervertebral disc in the standing position is small, and the pain is also light, so we say that “standing and talking without back pain” is scientifically justified. Generally speaking, the pressure of the intervertebral disc in the standing position is 1/2 of that in the sitting position. After saying “standing and talking without back pain”, we have to say another Chinese “famous saying”: “better to eat than dumplings, comfortable than lying down “. In fact, the above has basically made the reason clear, lying position, the intervertebral disc is no longer subject to the pressure of the weight, and the muscle is also relaxed, only light contraction, so the spring pressure is also greatly reduced, at this time the pressure on the lumbar intervertebral disc is only 1/4 of the standing position, the original pain will also be greatly reduced, or even disappear, so we say “comfortable than lying ” or “comfortable as lying down”, which is also the reason why doctors require patients with low back pain to lie flat on a hard bed to rest. For the same reason, patients with lumbar disc herniation are often asked to tie an elastic waistband with steel plates. The combination of these two can greatly reduce the pressure on the intervertebral discs, and the pain symptoms will improve significantly, while the lumbar circumference can also be fixed to protect the lumbar spine, making it less susceptible to cold and sprain. In summary, the pressure on the lumbar disc, lying: standing: sitting = 1: 2: 8, the reason we all understand, suffering from lumbar disc herniation should be how to do, I believe we are also clear, that is – not sitting less standing more lying bed, really want to move to tie the waist circumference.
