Subluxation: The Articular Lesion
Central to the philosophy, science, and practice of chiropractic is the vertebral subluxation. Part One of this book discusses the fundamentals of subluxation, the primary articular lesion treated by chiropractors. Long one of the most controversial concepts of the principles of chiropractic, the enigmatic subluxation will be discussed in Part One through the reductionistic model of mechanical joint dysfunction. Palmer’s early concept of the subluxation applied a mechanical model whereby the body part, that is, the spinal articulation, is not working, and the chiropractor fixes or adjusts it. The subluxation as a mechanical breakdown is like a carburetor that must be adjusted. A reductionistic practitioner might be satisfied with this analysis and send the car out of the shop after an adjustment. Following this model, Part One presents evidence of subluxation as mechanical joint dysfunction and establishes the foundation for the more complex theories presented in Part Two and the clinical manifestations of subluxation discussed in Part Three.
