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