The Subluxation Complex
The subluxation complex is a theoretical model of motion segment dysfunction (subluxation) that incorporates the complex interactions of pathologic changes in nerve, muscle, ligamentous, vascular, and connective tissues. First described by Faye as a paradigm shift from the static misalignment or “bone out of place” concept of subluxation, the vertebral subluxation complex has served as a more dynamic and inclusive teaching and research model for the chiropractic profession. According to Kuhn, a paradigm prepares students for membership in the scientific community with which they will later practice. By joining a group who learned the bases of their field from the same model, subsequent practice provides a basis for agreement over fundamentals. An accepted paradigm must seem better than alternatives but does not necessarily explain all the facts with which it can be confronted. It suggests which experiments are worth performing and selects phenomena in more detail for more rigorous study. Supporting Palmer’s concept that the neurologic component of the subluxation is the cornerstone of chiropractic theory, the subluxation complex provides a structure to better understand the foundation principles of chiropractic theory and provides a paradigm for chiropractic education and research.
Chapter 9
“The Vertebral Subluxation Complex” presents an overview of the subluxation complex paradigm, outlining the areas affected by the articular subluxation. The interaction of the pathologic changes of the nerve, muscle, ligamentous, vascular, and connective tissue components is discussed. Taking the subluxation concept beyond that of a biomechanical lesion, this chapter explores the functional manifestations associated with the articular lesion.
