Inversion therapy involves being upside down or at an inverted angle INVERSIONresulting in relief from pain. This process is called inverting. Inversion tables are designed to use gravity to relieve some of the pressure on the spine, which becomes compressed over time. The theory of inversion table use is that hanging upside down or at an angle where your head is lower than your feet will decompress the spine, which should relieve the pressure and pain.
