For people with degenerated and/or herniated discs, as well as those. Who wants to prevent such problems? It is important to find ways to cut the pressure on your intervertebral discs during the day. While it would seem that the best way to do this is to either lie down as much as possible. Or wear a lumbar belt, these two methods lead to a decrease in muscle strength. Around the spine, making the situation worse.
Understanding postural and biomechanical influences. Can help you learn to move and hold yourself. In a way that reduces the stress on your discs throughout the day. A series of studies on spinal loading can be instructive for this purpose.
Positions and movements
There is a lot of research that shows that the pressure in your discs affects by different positions. Different studies give different values for different positions. But there is good general consistency between some. found that disc pressure was almost identical and low when lying either face down. Or on its side (0.1 MPa and 0.12 MPa, ); standing 0.5 MPa; standing. Bent forward 1.1 MP; with unsupported seating, 0.46 MP; in a sitting. Forward bend, 0.83 MPa; relaxed seating, 0.3 MPa; lifting weights. With rounded backs, 2.3 MPa; with weights close to the body 1.1 MPa. When bending the knees when lifting 1.7 MPa; finally. An increase in intradiscal pressure by 14 MPa throughout the night.
Why is this significant? First, these numbers show how movements like bending forward and keeping. Your knees straight when lifting affects your discs. They also show that the pressure in the disc is higher in the morning than at night (when the discs compress. When we stand, sit and move during the day. They release some of their fluids; during the night. The fluids accumulate and increase. the pressure in the disc). This second fact suggests that it's best not to do movements that increase disc. Pressure—such as bending and lifting—until we've been up and moving for a while.
The results of this study are similar. But not consistent with another study conducted by Katsuhiko et. al. These latter researchers used a different. Unit of measurement (N) for pressure, but the comparison is simple. Because we can see the results of each other. Note that Wilke's study did not specify the exact positions the subjects were in. Sitting upright, which is generally considered. Best for the back, and puts more pressure on the spine than standing, according to this study.
There are important things to consider from other studies as well. First, the results of the two studies above may suggest that lying on your stomach at night is best for your back. When you sleep on a mattress, your lower back tends to sink in, creating a raised arch and tight muscles. Lying on your side with a pillow between your knees or lying on your back. A pillow under your knees is generally considered best.
Second, a study by Owens et. al. (2012) showed that using lumbar support while sitting can reduce the load on the lumbar spine by up to 50%.
Third, Nicholson and Morris found. Sitting in an inclined position reduces pressure on the spine by 50%.
Sitting can cause the greatest intradiscal pressure of any static position. Leaning forward, especially with a rounded back, puts a lot of pressure on your spinal discs. Proper body mechanics—bending your knees when lifting. Lifting objects close to your body, maintaining a neutral spine. When lifting—are essential to reducing stress on your discs.
