Spinal decompression is a form of mechanical spinal traction, which refers to the separation of the bones, joints, and discs of the back. It is theorized that this separation relieves pressure on the nerves in the back and helps decrease pain, and thus, improve function.
Spinal decompression devices use the same basic principle of spinal traction that has been offered by chiropractors, osteopaths, and other appropriately trained health professionals for many years.
Both traction and decompression therapy are applied with the goals of relieving pain and promoting an optimal healing environment for bulging, degenerating, or herniated discs.
