Massage is the manipulation of superficial and deeper layers of muscle and connective tissue using various techniques, to enhance function, aid in the healing process, decrease muscle reflex activity, inhibit motor-neuron excitability, promote relaxation and well-being, and as a recreational activity.

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.

Target tissues may include muscles, tendons, ligaments, fascia, skin, joints, or other connective tissue, as well as lymphatic vessels, or organs of the gastrointestinal system.

In professional settings massage involves the client being 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.
