Cold laser therapy is a cousin of acupuncture where a laser is used, instead of needles, to stimulate acupuncture points and influence the flow of energy through biomeridians.  Acupuncture traditionally involved the insertion on needles at specific points on the body to access the meridians of the body.  Once inserted, the needles are stimulated either by spinning, flicking, or by connecting them to an electric current via a battery pack. (Traditional acupuncture will not be discussed further in this article.  For a complete discussion, please visit: Acupuncture.)  With cold laser therapy, the laser replaces both the needle and the need for stimulation with light.  The major draw of cold laser is its non-invasive nature (no needles in the body) and the ability of the patient to administer the therapy themselves, either in the office or at home, once the proper acupuncture points are identified.  Cold laser therapy is also referred to as low-level laser therapy and Photobiomodulation.
