Doctor - my chiropractor does use a thompson table and he also uses an instrument called an activator I think, that is like a tiny little jackhammer that gently nudges the bone into place and is hooked up to a computer. (it's a bit more complex than that) There is no twisting or cracking the back. He also adjusts the ribs and extremities. He lives near me and I met him when he came to our garage sale. My neighbor uses his girlfriend who also uses the same techniques and she just had everything good to say about her - when I wound up with a slipped disk a few weeks ago I called him (he had given me his card) up because the pain was at least a 10 and constant and I could not even sit or find any position that was the least bit comfortable. So far I would say it is going great because the pain is 80% gone - there is still a lot of adjustment left to go though. I'm not all better, but I am a lot better. I think his technique is working pretty well.
Are you familiar with this? It was a new thing to me and I have gone to chiropractors quite a bit over the years
Anyway my neighbor accused me of just manufacturing the whole thing so I could go see him because he is drop dead gorgeous. LOL .... he is.....but I didn't I swear!
