Acupressure is a traditional Chinese medicine (TCM) technique based on the same ideas as acupuncture. Acupressure involves placing physical pressure by hand, elbow, or with the aid of various devices on different acupuncture points on the surface of the body.
Acupressure Points used in treatment may or may not be in the same area of the body as the targeted symptom. The TCM theory for the selection of such points and their effectiveness is that they work by stimulating the meridian system to bring about relief by rebalancing yin, yang and qi (also spelled "chi").
Many East Asian martial arts also make extensive study and use of acupressure for self-defense and health purposes (chin na, tui na). The points or combinations of points are said to be used to manipulate or incapacitate an opponent.
