Massage involves working and acting on the body with pressure – structured, unstructured, stationary, or moving – tension, motion, or vibration, done manually or with mechanical aids. Massage can be applied with the hands, fingers, elbows, knees, forearm, feet, or a massage device. Depending on the application and technique used, massage is used to promote relaxation and well-being, and is beneficial in treating sports injuries and other problems affecting the musculature of the body such as postural misalignment and many painful conditions.
In professional settings massage clients are treated while lying on a massage table, sitting in a massage chair, or lying on a mat on the floor, while in amateur settings a general purpose surface like a bed or floor is more common. Aquatic massage and bodywork is performed with recipients submersed or floating in a warm-water therapy pool.
