The zero-gravity® concept is credited to the scientists and doctors at NASA and was utilized in the space program to reduce the amount of compressional forces exerted on the spine by the extreme speed at which the astronauts blast into space. During take-off, astronauts recline with their feet higher than their hearts with a torso to leg angle of 126 degrees +/- 7. The reason zero gravity® is a preferred posture for astronauts is any slight amount of disc compression will be exemplified by the speed and force of take off.
A zero-gravity® posture is the only position that does not exert compression on the discs. And when gravity is neutralized, muscles rest and discs return to their normal size and shape.
A Word Of Caution:
The spine should not recline to 180 degrees with the knees raised for any length of time, which happens when a person lays flat on the floor with the knees raised much higher than the heart. The reason is this posture will increase the pressure on the brain and may cause Intracranial Pressure or ICP.
Zero Gravity® furniture will not allow the user to obtain these detrimental positions because the back will not recline to 180 degrees by design. The zero gravity® recliner was designed purposely to avoid the negative affects of ICP.
Zero-Gravity® furniture is designed to relieve the body of the pressures that cannot be relieved in a standing, seated or laying position or with other furniture that position the torso parallel to the horizon.
Why is a Zero–Gravity® recliner better than a traditional recliner?
'…The disc in between each vertebrae is a weight bearing structure whose normal consistency mimics jelly. Within twenty minutes to an hour if the disc does not move it will settle into an abnormal state that mimics the consistency of clay. It does this because after age ten the intervertebral disc begins to loose its blood supply and by the time we are fully grown we have lost the majority of it. To receive nutrition and maintain its health, the disc will absorb fluid from the surrounding tissue by motion through a process called osmosis, the more movement of the vertebrae the healthier the disc.
The very last disc in the body, L-5S1, absorbs the largest percentage of the weight of the upper body. Sitting loads the discs the most. Normal sitting postures will load 150 pounds of compression on L5/S1, standing loads 100 pounds and laying down will load at least 25 pounds. Even a minor back or disc problem can be exacerbated with 25 pounds of compression. The body's first reaction to any insult is inflammation.
A zero-gravity® seated position zeros out the compressional forces of the disc, thereby relieving the discomfort and more importantly the cause of the problem.'— Dr Mark Vettraino
