Millions of people suffer from chronic lower back pain. There are
many different causes and conditions involved, but a fairly
simple device can eliminate or greatly reduce the pain,
Most people with this pain find that the pain is greatly reduced when lying down. The reason for this is that the weight of the upper part of the body acts to compress the vertebrae together when standing or sitting, but that effect of compression disappears when prone.
TheoryThe upper part of a person's body is generally more than 1/3 of the entire body weight. The way a person is arranged, that weight is NOT distributed throughout the waist area, but is concentrated in the very small area of the spine itself. If a person's upper body weighs 70 pounds, and that weight is supported on a stack of vertebrae and disks that have an effective area of 1/2 square inch, that means that the continuous pressure on a disk is around 140 pounds per square inch! It gets even higher if the person carries anything.
Virtually normal movement (and appearance) is available when using this device. There is not the "rigid" structure like that of conventional traction equipment, and it follows the body contours fairly well.
