A person who practises chiropractic – mainly a system of physical manipulations of minor displacements of the spinal column. These minor displacements, or SUBLUXATIONS, of the spine are believed by chiropractors to affect the associated or neighbouring nerves and so cause malfunctions of the muscles throughout the body. By manipulating the affected part of the spinal column, the patient's problem is relieved. Chiropractors are regulated by the General Chiropractic Council.
