I have had this procedure done and it is the truth.  Way more advanced than any other form of Chiropractic care.  It is easy and painless.  My legs were off balance and one leg was longer than the other.  After my adjustment I was walking funny due to the fact that I was not use to my legs being even and used to walk to compensate my balance or lack there of.  I have went back for several visits and it was the precursor into my year long journey towards setting things straight.  If you think about it why would god make us do the old Chiropractic way of things with pulleys and levers and so much time taken to correct things..  I am a true believer that we are given every thing we need in the natural world.  Thus the atlas bone is one of those things that is built into the body like a dial used to adjust the spine at the slightest tweak.  Do your self a favor and do your research and find a local practitioner or NUCCA in your area…
