Introducing Spine-Worx So what is Spine Worx? Spine-Worx is a medical device which gently guides misaligned vertebrae into their correct positions and holds them there while tense muscles relax and stretch, to relieve back pain and related symptoms. Spine-Worx padded ridges and unique contours apply even pressure where it is needed and sustain it over several minutes time. Because Spine-Worx uses only your own body weight to control applied pressure, it automatically matches each individual s requirements. By shifting your weight or changing position slightly, you can apply more pressure where needed to feel fast relief.
