Non-surgical spinal decompression is achieved through the use of a mechanical traction device applied through an on-board computer that controls the force and angle of disc distraction, which reduces the body’s natural propensity to resist external force and/or generate muscle spasm. This enhanced control allows non-surgical spinal decompression tables to apply a traction force to the discs of the spinal column reducing intradiscal pressure, unlike previous non-computer controlled traction tables.
The theory behind non-surgical spinal decompression is that significant distractive forces, when applied to the lumbar spine in variable directions, can create a negative pressure in the center of the intervertebral disc, thereby creating a suctioning effect or vacuum phenomenon in order to retract or reduce the size of the herniated or bulging disc's gelatinous internal nucleus pulposus, thus diminishing or eliminating nerve compression, while at the same time creating an osmotic gradient which helps bring nutrients and water into the disc. Since intervertebral discs have poor circulation, they depend upon receiving their nutrition through diffusion across the end plates of the vertebrae above and below.
The appeal of non-surgical spinal decompression is that it is a non-invasive, non-surgical, drug-free alternative treatment for low back pain, sciatica, disc degeneration, disc bulges, disc herniations, and facet syndrome. There is copious anecdotal evidence of its effectiveness and more case studies are being published demonstrating very positive results in patients who have tried other conservative treatments that have failed.
