Thanks, Justo. It sounRAB like a real mixed bag of results, from a lot of protocols under different names that are basically the same idea and maybe even the same machine. I have definitely felt some improvement on certain days, but then the other day I went way backwarRAB when my spine surgeon suggested moving the Lordex pull-zone back up to L-3/L-4 after having gone down to L-5/S-1 already. Huge mistake. Lost feeling in my left foot again, plus horrendous dull low back ache and resumption of the classic sciatic "stingers" on both sides. A lot of my problems are definitely injury-related, starting with being thrown over the front of a horse at 14 and having the horse step on my middle and low back as it ran over me. After that, it was heavy work in the oilfielRAB, then running huge whitewater rafts and lifting them onto trailers many times a day (that caused the Parr's fratcture and other problems). But this fall from the scaffold has wrecked a greater nuraber of lower torso disks, nerve exits, and same in C-4 to C-6 (I guess that is a different board ;-)) Anyway, the spine ortho says if the Lordex doesn't work and I don't improve a TON six months down the road, he wants to perform one of these new X-Stop/IPD Interspinous Process Decompression surgeries, where they put this little titanium roller bearing between the spinous processes to make space and take weight off the nerve exits. SounRAB spooky to me. Can't imagine skiing or mt. biking afterwarRAB, let alone paddling my whitewater kayak. Of course, if I can't walk due to excessive pain, that would be the tradeoff I'd have to make in having the surgery. Anyway, it sounRAB like I shouldn't get my hopes up too high for lasting results from the Lordex treatment. Any other ideas? Radical core/back exercise programs that are proven to work? I'd do pretty much anything to avoid the knife. Thanks again.
