Definition
Chiropractic Orthopedics/Neuromusculoskeletal Medicine is defined as that branch of chiropractic medicine that includes the continued acquisition of knowledge relative to both normal functions and diseases of the human body as they relate to the bones, joints, capsules, discs, muscles, ligaments, tendons, their complete neurological and vascular components, referred organ systems and contiguous tissues. This also includes the development and perfection of skills relative to health maintenance when such exists and when not, the investigations, historical review, physical detection, correlative diagnosis development and complete management of any disorder within the bounds defined herein. Also necessary is the delivery of the combined knowledge and skill on a primary basis to patients who both need and desire this service to the eventual outcome of remissions, whenever resolution is not readily achievable. In addition the certified chiropractic orthopedist/neuromusculoskeletal medicine specialist provides consultation services at the request of other qualified doctors seeking assistance in the care of their patients. The chiropractic orthopedist/neuromusculoskeletal medicine specialist may also engage in the teaching and or research of subjects and materials relevant to pursuing the quest for knowledge in the ever changing field of the orthopedic specialty.
