Acupressure is a therapeutic technique of applying digital pressure (pressure applied by the digits or hands) in a specific way on designated points on the body. By applying pressure to one or more acupoints, practitioners correct imbalances by stimulating or easing energy flow. The acupoint most commonly investigated and accessible is P6, which is located on the anterior surface of the forearm, approximately three finger-widths from the wrist crease. Acupressure devices also have been developed; these are considered passive forms of pressure and differ from digital pressure. The Sea-Band® device is an example of a commercially available acupressure device that is a plastic stud incorporated into a wrist band to exert pressure on the P6 acupuncture point. The H7 acupressure point at the wrist has been used to treat insomnia. Acupressure has been examined for its effect on anxiety, chemotherapy-induced nausea and vomiting, depression, fatigue, pain, and sleep/wake disturbances.
