I can totally relate, Steve, because I am going through something similar: two bulging discs in the lumbar and level 2 spondy. the Pain was hard to describe to anyone who's never had back pain.
I'm not saying that inversion tables don't work and I'm not saying that the ActiPatch doesn't work. I'm saying that the medical community views them both as placebic because they are cautious and don't trust clinicals with small sample sizes.
I drove for Mayflower for 15 years and basically abused my body for 45 years (I'm 65 now) by lifting heavy things, carrying heavy things, working on ladders, etc. If ANYONE has a compressed back, it's me. I might buy an inversion table even though I have spondy -- all the articles I'm reading say that it's a contraindication if you have spondy -- but my P/T and spine doc both said they see no reason I should AVOID an inversion table, even with my level 2 spondy. They said "don't tilt it very far and start with short sessions."
The main point of my post is: the doctors wouldn't prescribe or even recommend an inversion table.
The ActiPatch absolutely did NOT work for me, and I tried it twice a few years ago -- once on my shoulder, once on my back. ZERO benefit. Annoying to keep that thing in place, but I did. I believe that clinical for back pain proved a slight benefit for SOME, meaning it's not completely a placebo, but I want someone to explain why it works for some people but not for others. What is the science there? Body density? Chemical composition of tissue? Humidity?
I'd also like to know why the Koneru Brothers' clinical trial failed?
