The Need for Increased Attention to Low‐Level Laser Therapy as Treatment for Wounds and Ulcers

Abstract

Light amplification by stimulated emission of radiation (lasers) is a device that typically generates electromagnetic radiation of uniform wavelength, phase, and polarization. The term low-level laser therapy (LLLT) is broadly defined as the therapeutic benefit of lasers. This review aims to discuss the positive effects of LLLT on skin wounds, diabetic foot ulcers, and burn healing. Different LLLT protocols have been widely used as treatment for these conditions to accelerate tissue regenerative processes. We have classified eligible papers in the fields of skin wounds, ulcers, and burns into in vivo and in vitro experimental studies and clinical trials that evaluated the use of LLLT as treatments that promote healing. An electronic search of scientific peer reviewed papers was conducted in the PubMed database. Our search has shown that the use of LLLT in biology and medicine is growing rapidly, and advancements in LLLT research dramatically improved the clinicians' ability to safely and effectively treat wounds and ulcers. There is increased clinical use of laser for wound and ulcer treatment. Several recent studies have confirmed the potential beneficial effects of LLLT for wound healing.
