"Would you buy a Hyundai based on Volvo safety rating?"
"No! So, when someone quotes you VAX-D research and then shows you a different table, DO NOT EXPECT THE SAME RESULTS" Due to the unprecedented success of VAX-D with low back pain there are many Copy-Cat machines quoting VAX-D research. Beware of other traditional traction tables that advertise as decompression. VAX-D is a patented technology that is cleared by the FDA. It has published RESULTS and proven decompression of the disc (study #1 below.) Ask any doctor to see the research! Every week, I see patients who have tried other so-called "decompression" tables. Be careful what they are selling you.
