“Articular dysfunction” means an alteration of the biomechanical and physiological dynamics of a joint of the axial or appendicular skeleton.
“Musculoskeletal disorders” means abnormalities of the muscles, bones, and connective tissue.
“Chiropractic differential diagnosis” means a diagnosis to determine the existence of a vertebral subluxation complex, articular dysfunction, or musculoskeletal disorder, and the appropriateness of chiropractic care or the need for referral to other health care providers.
“Chiropractic adjustment” means chiropractic care of a vertebral subluxation complex, articular dysfunction, or musculoskeletal disorder. Such care includes manual or mechanical adjustment of any vertebral articulation and contiguous articulations beyond the normal passive physiological range of motion.
