Overview

The World Chiropractic Alliance (WCA) is a United States not-for-profit organization founded in Arizona in 1989. It represents and promotes a traditional or “straight” chiropractic philosophy centered on the detection and correction of vertebral subluxations, drug-free care, and a vitalistic understanding of health. The organization presents itself as an advocate for chiropractors who believe that chiropractic should retain a distinct identity rather than becoming primarily a form of musculoskeletal or quasi-medical treatment. A central WCA position is that spinal adjustments may be appropriate for people whether or not they report symptoms or have a conventional medical diagnosis. The organization has also promoted the idea that chiropractic care can begin in infancy and continue throughout life. These positions distinguish it from the more mainstream “mixer” approach, under which chiropractors may combine spinal manipulation with broader medical, rehabilitative, or evidence-based clinical methods. The WCA’s philosophy has produced sustained disagreements with larger professional bodies, especially the World Federation of Chiropractic. The Alliance has challenged the federation’s authority to define chiropractic’s professional identity or speak for all chiropractors internationally. Its public advocacy has emphasized the preservation of subluxation-based practice, opposition to restrictions on the number or duration of chiropractic visits, and resistance to claims that chiropractic should be limited mainly to back or neck pain. The organization has also taken positions on safety and public-health issues that have attracted criticism. It has rejected the view that chiropractic neck adjustments pose a significant stroke risk and has opposed vaccination. It has asserted that adjustments can positively affect the immune system, although the cited reference material notes that reviewed evidence did not validate that theory. These positions place the WCA outside the consensus of many medical and public-health authorities. Membership is described as open to chiropractic doctors and students. Policy and administration are handled through a board-of-governors structure, supplemented by an International Board of Governors whose membership has not been fully disclosed in the referenced material. The organization has published or been associated with The Chiropractic Journal and has engaged in professional lobbying and advocacy, although its lobbying activity appears to have declined or ceased after the mid-2000s. The WCA’s history also includes controversies. In the early 1990s, its founder and other associated figures were implicated in the Arizona political-contribution scandal commonly known as AzScam. The referenced material states that Terry Rondberg and another founder, William Immerman, entered agreements concerning civil allegations of illegal contributions and paid fines. The organization and associated individuals were also linked to the Vertebral Subluxation Research Institute, a program criticized for teaching patient-recruitment methods that allegedly encouraged chiropractors to obtain “research volunteers” and convert them into continuing patients. That program ended in 1991. In later advocacy, the WCA opposed media and public campaigns highlighting possible risks from chiropractic treatment. In 2003 it joined the American Chiropractic Association in criticizing coverage of research on risks associated with chiropractic neck manipulation. In 2006, its attorneys demanded removal of transit advertisements seeking people who believed they had been injured by chiropractic care, and the organization subsequently promoted an anti-defamation campaign. The WCA therefore occupies a distinctive position in chiropractic: it is a professional advocacy body focused on defending a traditional subluxation-centered model, while remaining controversial because of its views on evidence, safety, vaccination, and patient care.

History

The World Chiropractic Alliance was established in Arizona in 1989 by Terry Rondberg and associated chiropractic advocates. From its beginning, the organization focused on defending a “straight” or traditional form of chiropractic that treats vertebral subluxation as the central object of care. This orientation favors spinal adjustment, drug-free practice, and a vitalistic account of health, while rejecting the idea that chiropractic should be defined mainly as treatment for musculoskeletal pain. The WCA’s philosophy has consistently differed from the “mixer” model practiced by many chiropractors, which may incorporate medical diagnosis, rehabilitation, medication, or other mainstream clinical methods. The Alliance has argued that subluxation-based care should be available to asymptomatic people and has opposed professional or legal requirements that symptoms or a medical diagnosis be present before adjustments are provided. It has also promoted the view that chiropractic care can begin at birth and continue throughout life. During the early 1990s, the WCA and people connected with it became involved in two controversies. A WCA lobbyist was implicated in Arizona’s AzScam political-corruption investigation. The reference material states that Rondberg, Immerman, and other WCA principals were linked to illegal political contributions and that Rondberg and Immerman later entered civil agreements with the Maricopa County Attorney’s Office and paid fines. The organization was also associated with the Vertebral Subluxation Research Institute, a program criticized for encouraging chiropractors to recruit people as research volunteers and subsequently seek to retain them as patients. The program ended in 1991. The Alliance developed an adversarial relationship with the World Federation of Chiropractic, disputing the federation’s ability to define chiropractic identity or represent the profession internationally. The WCA has portrayed itself as a defender of practitioners who believe that mainstream professional groups have reduced chiropractic to a limited musculoskeletal service. This advocacy extended to public disputes about the safety of neck manipulation, the appropriate number of visits, care for children, and the legitimacy of subluxation theory. In 2002, Leona Marie Fischer, described as a WCA International Board of Governors member, represented the organization on a chiropractic advisory committee associated with the United States Department of Veterans Affairs. In 2003, the WCA joined the American Chiropractic Association in criticizing news coverage of a Neurology report concerning risks associated with chiropractic neck adjustment. In 2006, the organization’s attorneys challenged bus advertisements placed by a chiropractic-injury awareness group, and the WCA subsequently described its response as an anti-defamation campaign. The WCA has also taken controversial positions on vaccination and immune-system claims. It has opposed vaccinations and argued that chiropractic adjustments have beneficial effects on immunity, although the referenced material reports that reviewed data did not substantiate that proposition. The organization denies that chiropractic adjustments pose a significant stroke risk, a position that has contributed to disputes with critics and public-health commentators. Membership is open to chiropractic doctors and students. The organization is governed through a board structure and has referred to an International Board of Governors, although the referenced account says that it has not publicly identified all members. Terry Rondberg is identified as founder and chief executive, with Timothy J. Feuling as vice president, Cindy Rondberg as chief financial officer, and Barbara Bigham as communications director. The WCA has operated as a nonprofit advocacy and professional organization rather than as a commercial consumer brand.
