In the United States, William H. Fitzgerald, MD, who is frequently referred to as the
father of reflexology, wrote in 1917 about ten vertical zones that extended the
length of the body. He found that the application of pressure to a zone that
corresponded to the location of an injury could serve as relief of pain during minor
surgeries. Reflexology is the application of appropriate pressure to specific points
and areas on the feet, hands, or ears. Reflexologist believe that these reflex points
correspond to different body organs and systems, and that pressing them has a
beneficial effect on the person health.
