For patients with L5/S1 herniation, the optimal sleeping position has the following requirements: First, the sleeping position should be supine. Because at this time, if the patient adopts the side lying position, it may cause the twisting of the trunk, which may lead to more serious stimulation of the intervertebral discs in this area to the surrounding nerve roots; Second, it is necessary to maintain the lumbar hyperextension position. The so-called lumbar hyperextension refers to the lumbar region to continuously maintain a forward convex arc. At this time, the patient needs to pad a small soft pillow in the lumbar region, so that the lumbar region continues to be over-extended. This allows the lumbosacral region to maintain a constant angle of inflection. At this time, the protruding intervertebral disc will have a certain degree of retraction, and the compression of the peripheral nerve root is reduced; Third, the patient can be asked to put a small pillow on the back side of the bilateral knee joint. This will keep the patient’s bilateral knee joints in a certain degree of flexion. The purpose of doing this is to reduce the tension on some of the large nerve trunks in the lower extremities, like the sciatic nerve. Once the nerve tension is reduced, the compression and irritation in the lumbar spine will be significantly reduced.
