Supporting a Complex Position

Supporting a Complex Position

by: Lisa K. Bloom, DC, DACS, DIBCN

More than a century ago Daniel David Palmer set his hands to the spine of Harvey Lillard and, in Palmer’s own words, “racked (vertebrae) into position by using the spinous process as a lever.” (1) At the time, Palmer had no philosophy, no science, and no semblance of what was to be the art of chiropractic – yet a deaf Harvey Lillard reportedly found his hearing restored shortly after this first chiropractic adjustment. It appears that Lillard was selected as a subject for Palmer’s experiment because of his deafness. Palmer in the truest sense practiced medicine without a license when he used his manual treatment for the purpose of affecting a specific condition, and he was successful.

As history tells us, Palmer’s systematic investigation for the cause of all disease revealed that various health problems frequently resolved or abated while undergoing chiropractic care. It was this success, combined with his knowledge of neurology, that led Palmer to the premise that the presence of subluxation, and therefore the chiropractic adjustment, could affect all systems of the body. Definitions of the vertebral subluxation and the statement of purpose of chiropractic care – as established by the Association of Chiropractic Colleges, the American Chiropractic Association, and the International Chiropractic Association – all contain a phrase which infers that we intend to affect all body systems and impact general health. In spite of history and the standards we set by our own definitions, the current political climate within the chiropractic profession can be summed up by the following statement:

“The issue of whether chiropractors have a role in the management of patients with visceral disorders is so sensitive politically, and open to exploitation by others saying this is evidence of unscientific practice, that some have questioned whether or not it might be better for the general advancement of the profession to jettison all claims in this area.” (2)

This statement underscores the sacrifices a portion of the chiropractic profession is willing to make for the sake of acceptance into a medical model of healthcare that medicine itself is changing. It is also curious that medical specialists who practice spinal manipulation have noted the ability to influence conditions other than back pain. (3,4)

The other side of the story is equally interesting. Investigations by medical doctors in the 1930s revealed a “viscerospinal syndrome” which involved the symptoms of asthma, angina, dysuria, pyloric and esophageal spasm. The physicians noted x-ray and physical examination evidence of scoliotic changes, changes in lordotic and kyphotic curves of the spine and evidence of leg length inequality. When the musculoskeletal abnormalities were addressed and treated, a relief or resolution of the apparent visceral symptomatology resulted. (5-7) A 1954 study demonstrated that irritation to spinal structures resulted in pallor, diaphoresis, nausea, bradycardia, and syncope. Of note is that these symptoms were most prevalent in subjects who concurrently complained little of the pain. (8) It has since been demonstrated in animal and human models that irritation (noxious stimulation) to spinal structures produces changes in sympathetic nervous system activity, resulting in measurable changes in the function of the target tissue. (9-17)

A myth often generated about the chiropractic profession is that there is no scientific research to substantiate chiropractic treatment. When the profession is without an evidenced-based knowledge base, we have no choice but to concede. The purpose of my lecture is to provide an accessible, evidence-based presentation that demonstrates and supports the biomechanical and neurological effects of the vertebral subluxation complex and provides a focused source containing the current research available.

David Chapman-Smith stated, “at one end of the spectrum some chiropractors continue to make outrageous claims, at the other end some avow that chiropractors should only treat patients for musculoskeletal pain.” (18) In order to appropriately respond to this statement, we need an evidence-based, contemporary understanding of the vertebral subluxation. In addition, we need to bring the profession up-to-date, facilitate inter-professional communication, and provide the information necessary to document the need for and the basis of chiropractic care.
