I was tricked into watching this (just the first few minutes until I realized it was an infomercial). I was visiting my folks, looking at cable. Their guide is totally different than mine, and I saw a program called "End Back Pain Now". I thought I was going to see some kind of informative programming, not a commercial. I was so miffed when I found out I was duped!
It is just passive joint movement. It probably feels great, but I would recommend my clients just lie on their back, pull their knees to their chest & draw small circles with the knees.... along with some other stretches, & save the $200.
