Nonsurgical spinal decompression is a type of motorized traction that may help relieve back pain. Spinal decompression works by gently stretching the spine. That changes the force and position of the spine. This will take pressure off the spinal disks, which are gel-like cushions between the bones in your spine.
Over time, negative pressure from this therapy may cause bulging or herniated disks to retract. That can take pressure off the nerves and other structures in your spine. This in turn, helps promote movement of water, oxygen, and nutrient-rich fluids into the disks so they can heal.
