The word “Chiropractic” is derived from the Greek words “cheir” (hand) and “praktos” (done) combined to mean “done by hand.” It was chosen by the developer of chiropractic care, Daniel David Palmer. In 1895, D.D. Palmer performed a chiropractic adjustment on a partially deaf janitor, Harvey Lillard, who later reported that his hearing had improved due to the change.
The treatment plan may involve one or more manual adjustments in which the doctor manipulates the joints, using a controlled, sudden force to improve range and quality of motion. Many chiropractors also incorporate nutritional counseling and exercise/rehabilitation into the treatment plan. The goals of chiropractic care include the restoration of function and prevention of injury in addition to back pain relief.
