Chiropractic, which loosely means to treat by hand, is a type of manipulative therapy that has been practiced in the U.S. for over 100 years. This discipline is based on the premise that function of the joints and muscles of the spine can have a profound effect upon health. Through a complex relationship with the nervous system, problems with vertebral (spinal) joints can result in local neck and back pain and even cause pain to be felt in the head, arms, and legs (referred pain). Chiropractors identify these problems in specific joints as chiropractic subluxations or joint dysfunctions. (Note: Medical doctors use the word subluxation in a different way, denoting a bone that has nearly dislocated.)

Acupuncture has been used to treat a variety of illnesses for more than 2,000 years. Acupuncture is a component of the traditional Chinese medicine (TCM) system of medicine.
