Spinal decompression is 88% effective for herniated discs both in the neck and lower back. It’s a great modality to use. What is does, is it creates a negative pressure inside those discs. Those discs are cushions in between your spinal bones. They actually give your spinal bones a little shock absorption. Well, the way the discs get their nutrients is through motion, like I said earlier. And if you stretch the back apart it actually creates a negative pressure inside those discs. So it will actually pull the disc material that’s actually herniated or putting pressure on the nerves or spinal column, it’ll actually pull that back in and on top of that it’ll give it nice healing and good nutrients to help the body heal that area much quicker.
