DR-HO'S 2-in-1 Back Relief Stretch & Support BeltThe Decompression Belt stretches and tractions the lower belt as it inflates with air. This gentle traction helps decompress the spinal discs. Decompression helps relieve pressure off pinched nerves, degenerative, herniated, and bulging discs. Relieving the pressure allows degenerative discs to get the water, oxygen, and nutrients they require for faster healing. It permits herniated and bulging discs to return to their normal position and condition.
