Low dose laser therapy (LDLT) has been available for the treatment of various diseases for almost two decades. The aim of therapy is usually to reduce pain. The literature offers a plethora of reports, some negative and some positive. This review discusses the relatively few placebo-controlled, double-blind trials on the subject, in an attempt to provide an evaluation of the clinical effectiveness of LDLT. The majority of these studies suggest that LDLT is not clinically effective. There is no particular disease or symptom which seems to respond to LDLT. The same can be said of the type of laser light or its intensity. Based on this collective data, LDLT does not seem to be a scientifically proven therapy.
