1. It helps to relax tight muscles by applying a gentle, intermittent stretch over a period of 10 to 15 minutes.
2. This stretch also decreases pressure on the discs and joints within the spinal column, which is how it can benefit conditions such as spinal stenosis, facet syndrome, degenerative disc disease, sciatica, muscle spasms, and disc herniation.
3. The intervertebral discs aren't well vascularized, meaning they naturally lack adequate blood supply. And the motion of decompression allows necessary nutrients to enter the injured disc tissue to promote healing and ultimately decrease pain.
