Hi Decruz, I have an elite seat which also helped to an extent.....but not a lot. What bothered me most was it's so hard on my back! I have tried padding it with pillow and towels, but I also don't know if doing it on a bed (I don't have one of those firm leather tables they have in pt.....wish I did!) makes you sink in and kind of throws you off. Since I started the astym I stopped the elite seat because of my back. My back pain is gone now (though my pt has also worked on my posture with exercises) so perhaps I should pull it out and try it again. I am going to try the Dynasplint for a short period of time to see if it helps and my pt is going to call Dr. Sevier and ask for suggestions. I'll post if I learn anything new. Also, does anyone know of any other piece of equipment for extension that is better?
