Massage therapy is one of the oldest healthcare practices known. References to massage are found in ancient African societies, and Chinese medical texts written more than 4,000 years ago. Massage therapy is the scientific manipulation of the soft tissues of the body for the purpose of normalizing those tissues and consists of a group of manual techniques that include applying fixed or movable pressure, holding, and/or causing movement to parts of the body. While massage therapy is applied primarily with the hands, sometimes the forearms or elbows are used. These techniques affect the muscular, skeletal, circulatory, lymphatic, nervous, and other systems of the body. The basic philosophy of massage therapy embraces the concept of vis Medicatrix naturae , which means “aiding the ability of the body to heal itself.”
