Back on Track traction reduces the painful spinal disc protrusions, bulges, and herniations. This traction also decreases spinal degeneration stenosis pain and numbness. The specialized traction treatment causes intra-discal pressure to drop from a positive to a negative pressure. This negative pressure promotes the diffusion, or intake, of water, oxygen, and nutrients into the damaged dehydrated disc, thereby rehydrating the degenerated disc.
