Acupuncture points are locations on the body that are the focus of acupuncture, acupressure, sonopuncture and laser acupuncture treatment. Several hundred acupuncture points are considered to be located along meridians (connected points across the anatomy which affect a specific organ or other part of the body). There are also numerous "extra points" not associated with a particular meridian.
They are different from Japanese shiatsu points, although Japanese acupuncture uses TCM acupuncture points.
Despite considerable efforts to understand the anatomy and physiology of the "acupuncture points", the definition and characterization of these points remains controversial. Research has been published suggesting acupuncture points may be associated activation of specific brain areas using functional magnetic resonance imaging or areas of low electrical impedance in the body but overall evidence for the anatomical existence of acupuncture points is not compelling.
