Objective: The purpose of this paper is to review and discuss the history of chiropractic vertebral subluxation (CVS) between the years 1966 and 1980, with an emphasis on consensus models and terminology.Discussion: The consensus models on CVS during this time were an outgrowth of previous model building, research, and practice methods. The first consensus models were developed by the radiology diplomates of the American Chiropractic Board of Radiology. Later work was used to develop Medicare standards. Research and theory were influenced by the 1975 National Institutes of Health conference on spinal manipulation in 1975 and the workshops that followed that meeting. A new historical consciousness about the CVS, developed at the National Institutes of Health conference, which was a turning point for the profession in the use of terminology and the focus on functional pathophysiology associated with CVS. The historical view of CVS developed by Watkins, Haldeman, and Janse led to new integrative and historical developments in the profession.Conclusion: Theories during this period included consensus efforts as well as new distinctions about CVS theory and terminology.
