The NUCCA procedure brings several generations of clinical research to correcting the serious problem of the Atlas Subluxation Complex. By using precise and objective x-ray views of the head and neck, mathematical measurement and analysis are made of the misalignment.

Once the misalignment is understood by the Dr. Collier, there is no need for further x-rays because correlating the relationship between posture and upper cervical misalignment allows posture to then be used thereafter to judge alignment. There is also often less need for repeated corrections because returning the bones of the neck to a normal position also normalizes function in the body.
