Nonsurgical Spinal Decompression is a type of motorized traction that helps relieve back pain. Spinal Decompression works by gently stretching the spine. That stretch changes the force and position of the spine. This change takes pressure off the spinal discs, which are gel-like cushions between the bones in your spine, by creating negative pressure in the disc. As a result, bulging or herniated discs may retract, taking pressure off nerves and other structures in your spine. This in turn, helps promote movement of water, oxygen, and nutrient-rich fluids into the discs so they can heal.
