Final answer:
The term subluxation was coined by Dr. Oakley Smith, a pivotal figure in the development of Naprapathy.
Step-by-step explanation:
The term subluxation was coined by Dr. Oakley Smith. A subluxation, in chiropractic theory, refers to a slight misalignment of the vertebrae, traditionally believed to be a cause of numerous health problems. The concept is central to the practice of chiropractic care, which involves the diagnosis and treatment of mechanical disorders of the musculoskeletal system, especially the spine.
Dr. Oakley Smith was one of the early practitioners who diverged from D.D. Palmer's theory of chiropractic's subluxations and developed his own theory which formed the basis for the school of Naprapathy.
