Massage therapy is the scientific manipulation of the soft tissues of the body for the purpose of normalizing those tissues and consists of manual techniques that include applying fixed or movable pressure, holding, and/or causing movement of or to the body. A body rock is a serpentine-shaped tool, usually carved out of stone. It is used to amplify the therapist’s strength and focus pressure on certain areas. It can be used directly on the skin with a lubricant such as oil or corn starch or directly over clothing. Bamboo and rosewood tools are also commonly implemented. They originate from practices in southeast Asia, Thailand, Cambodia, and Burma. Some of them may be heated, oiled, or wrapped in cloth.
