A pressure point is any area of the human body that causes pain or some other effect when manipulated. While it is known that relatively weak pressure can cause pain or injury when to specific areas of the body, whether or not such points can effectively be used for healing purposes, such as in acupressure or acupuncture, as unknown. Techniques targeting pressure points are commonly used in martial arts, as the use of said points can greatly increase the effectiveness of a technique. Most pressure points lie along major nerve pathways.
