Acupressure is an alternative medicine technique similar in principle to Acupuncture. It is based on the concept of life energy which flows through "meridians" in the body.
In treatment, physical pressure is applied to trigger points with the aim of clearing blockages in these meridians. Pressure may be applied by hand, by elbow, or with various devices.
Some medical studies have suggested that acupressure may be effective at helping manage nausea and vomiting, or for helping lower back pain.
Acupressure practitioners use their fingers, palms, elbows or feet, or special devices to apply pressure to acupoints on the body’s meridians. Sometimes, acupressure also involves stretching or acupressure massage, as well as other methods.
