Can Chiropractors and Evidence-Based Manual Therapists Work Together? An Opinion From a Veteran Chiropractor Samuel Homola, DC Abstract: Use of manual therapy in the form of manipulation and massage is evident in the earliest recordings of history. Today, manual therapy is an evidence-based practice that can be used with predictable results in the treatment of a variety of neuromusculoskeletal problems. However, for some manual therapists, treatment is still based on a belief system that incorporates vitalism, energy healing, and other metaphysical concepts. Cooperation of practitioners in researching the effects of manual therapy would require uniformity based upon the guidelines of science, following rules for selection of an evidence-based therapy that produces predictable and replicable results. Such an approach would not allow contami- nation by dogma or by an agenda that is designed more to support a belief system than to find the truth. The chiropractic profession, which began with a founding father in 1895, is identified primarily by its use of manipulation. But chiropractic is based upon a vertebral subluxation theory that is generally categorized as supporting a belief system. The words “manipulation” and “subluxation” in a chiropractic context have meanings that are different from the meanings in evidence-based literature. An orthopedic subluxation, a partial disloca- tion or displacement of a joint, can sometimes benefit from manipulation or mobilization when there are joint-related symptoms. A chiropractic subluxation, however, is often an undetectable or asymptomatic “spinal lesion” that is alleged to be a cause of disease. Such a subluxation, which has never been proven to exist, is “adjusted” by chiropractors, who manipulate the spine to restore and maintain health. The reasons for use of manipulation/ mobilization by an evidence-based manual therapist are not the same as the reason for use of adjustment/manipulation by most chiropractors. Only evidence-based chiropractors, who have renounced subluxation dogma, can be part of a team that would research the effects of manipulation without bias.

When it became apparent that chiropractic was hopelessly mired in subluxation chicanery, I began work on my book Bonesetting, Chi- ropractic and Cultism4, which was published in 1963. In the final sentence of its last chapter, I wrote: “…Unless the chiropractic profession as a whole specializes in the physical treatment of back disorders... and earns reciprocity with other healing professions, under the guidance of medical science, there will be no justification for the existence of chiropractic when an adequate number of medical specialists and medical technicians make scientific manipulation available in a department of medical practice…” Today, most chiropractic colleges include instruction in use of physical therapy modalities and other adjunctive procedures. A few colleges are still “straight,” teaching that spinal adjustment is the only treatment needed for Fig. 1: Author demonstrating lumbar spine manipulation most ailments, emphasizing “spinal analysis” rather than diagnosis. All of the colleges, however, still cling to the belief that adjusting the vertebrae will improve health subluxation theory2: “…The dangers of building up a by removing nerve interference, despite rejection of this revolutionary system of medicine based upon such a belief by medical scientists5,6. slender hypothesis, unsupported by scientific evidence, is so incalculable that it is our duty as guardians of the public health to fight against this menace...” I was also How Chiropractic Is Defined greatly impressed by the work of Mennell, a specialist In 1895, D.D.
