What truly differentiates doctors of chiropractic from any other healthcare professionals is the fact that chiropractors are the only professionals who are trained to diagnose and treat what are called spinal subluxations. The word “subluxation” comes from the Latin words meaning “somewhat or slight” (sub) and “to dislocate” (luxate). So the term ‘vertebral subluxation’ literally means a slight dislocation or misalignment of the bones in the spine.
