In 1902, what term did D.D. Palmer use to describe the cause of dis-ease?

D.D. Palmer, the founder of chiropractic, utilized the term "subluxation" to describe a critical concept related to the cause of dis-ease in 1902. Palmer theorized that misalignments of the vertebrae—specifically, the partial dislocation of vertebrae affecting the nervous system—could lead to various health conditions. This term reflects his belief that these subluxations could interfere with the body's innate intelligence and ability to heal itself, thus resulting in dis-ease.

The use of "subluxation" has historically been essential in chiropractic philosophy, as it signifies a specific type of misalignment that is thought to have a direct impact on nerve flow and overall health. Understanding this term is fundamental for anyone studying chiropractic, as it underpins many of the principles of diagnosis and treatment within the field.
