Scientific Spinal Decompression Therapy with Disk Dr WG50 Double. Spinal decompression is created as the back brace inflates with air. Patented VAP™ Technology decreases axial loading while increasing intervertebral disc space by anchoring underneath the rib cage pushing upwards and against the pelvic girdle pushing downwards. This action gently stretches the torso vertically and displaces stress away from the affected disc and nerve. Pressure and pain levels, within the lumbar spine region, is significantly reduced which can assist active-rehabilitation.
