Authors' objectives: This review aims to assess the effectiveness of low level laser therapy (LLLT) in the treatment of chronic wounds, specifically leg ulcers and pressure sores.
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 laser type and wavelength, the use of a single wavelength or a combination of wavelengths, irradiance or dosage, beam divergence, spot size, frequency and duration of treatment, applicator placement (contact or non-contact), and, for pulsed devices, pulse duration and duty cycle. - To date, neither Health Canada nor the US Food and Drug Administration have approved low energy lasers for use in wound healing. - Systematic reviews of the literature indicate that the efficacy of LLLT in this application is not established although it poses little or no safety risk to patients. There is no good scientific evidence to support its use and mounting evidence to indicate it does not benefit wound healing. - Any local use of LLLT in this application should be limited to research, in patients resistant to conventional therapy. - Other, possibly more promising alternative therapies, such as electrical stimulation and ultrasound, should be considered as adjunct therapies to conventional wound healing practices.
