Chiropractic care is a form of alternative medicine that focuses on the diagnosis and treatment of mechanical disorders of the musculoskeletal system, especially the spine. Chiropractors use manual adjustments and manipulation of the spine, as well as other therapeutic methods, to promote overall health and well-being. They may also provide advice on lifestyle and nutrition, and may order diagnostic imaging studies and laboratory tests. The goal of chiropractic care is to reduce pain and improve the function of the joints and nervous system.
