Authors' objectives: This report aims to assess the effectiveness of the use of low level laser therapy (LLLT) to assist wound healing.

Authors' recommendations: Low level laser therapy (LLLT) has been used in the treatment of wounds. Issues related to use of the technology in this application are definition of standard protocols and evidence of effectiveness. Low level lasers most commonly used for wound treatment are the gallium arsenide (GaAs), gallium aluminum arsenide infrared semiconductor (GaAlAs) and the helium neon (HeNe) devices. Differences exist in the delivery of LLLT. Variables include pulse rate, duration of treatment, applicator placement (contact or non-contact), wavelengths and spot size. To date, neither Health Canada nor the U.S. Food and Drug Administration has approved low energy lasers for use in wound healing. A systematic review of the literature indicates that the efficacy of LLLT in this application is not established. There is no good scientific evidence to support its use. Any local use of LLLT in this application should be supported by empirical data from good quality studies of its efficacy and effectiveness. Other, possibly more promising alternative therapies should be considered as adjunct therapies to conventional wound healing practices.
