NUCCA is an acronym for the National Upper Cervical Chiropractic Association. It was founded in 1966 by chiropractor Ralph Gregory and based primarily upon the work he and John Grostic had performed before Grostic's death in 1964. The new style of upper cervical adjusting technique was taught in 1966 at the first NUCCA seminar, which was held at the Howard Johnson Motel in Monroe, Michigan.[1]


NUCCA focuses on the upper vertebrae in the neck and claims to correct misalignment of the upper spine.[2] The method uses double-pivot-point X-ray analysis, the "development of the triceps pull manual adjustment" and "design and development of the Anatometer posture distortion measuring instrument". Unlike other chiropractic techniques, NUCCA does not use manual adjustments and does not involve twisting or popping.[3][4]


Upper Cervical Research Foundation

The research branch of  NUCCA, the Upper Cervical Research Foundation (UCRF), was established in 1971 and has been studying the link between the NUCCA work, the upper cervical spine and optimal well–being[5].

The Upper Cervical Monograph

The Monograph was started in March of 1973 to share articles of the technical aspects of NUCCA, reports on NUCCA research and chiropractic in general[6].

NUCCA and Blood Pressure

In 2007 NUCCA published Atlas vertebra realignment and achievement of arterial pressure goal in hypertensive patients: a pilot study. The study design used was  randomized, double blind, with a placebo control. The results of the study showed no adverse effects with marked and sustained reductions in blood pressure similar to the use of two blood-pressure medications given in combination[7].

Textbooks such as Eriksen's Upper Cervical Subluxation Complex[8] argue for the technique on the basis of empirical evidence in private practice and a review of associated concepts in published literature.
