Chiropractors, also known as doctors of Chiropractic, diagnose and treat patients whose health problems are associated with the  musculoskeletal and nervous systems, and the effects of these disorders on general health.

Chiropractors believe interference with these systems impairs normal functions and lowers resistance to disease. They also hold that spinal or vertebral dysfunction alters many important body functions by affecting the nervous system, and that skeletal imbalance through joint dysfunction, especially in the spine, can cause pain.
