Spinal Decompression involves axial traction being applied to the spine, where a vaccum is created, which can suck a minor disc bulge or herniation back into the annular ring of the disc. (Boyle's Law stating that temperature, pressure and volume being direcly proportional to each other. As the body temperature will remain constant, traction increases the volume of the disc space, so pressure must decrease, reducing the herniation).
The disc material has poor blood supply, and nutrients are provided by motion, so some spinal decompression can vary the traction force so that a slight pumping motion is made. Time, traction force and frquency of treatments vary according to the patient.
