What is Flexion-Distraction

Flexion distraction is a non-invasive, non-surgical table that can safely move the spine in a therapeutic stretch to alleviate pain due to disc pain such as herniation(s) and/or bulge(s) and take pressure off the lumbar spine. It is a slow, gentle, and controlled motion taking specific segments through a flexion-extension range in order to distract said segments.
