The use of phototherapy in the treatment of diabetic ulcers

Chronic ulcers are a common complication in diabetes. The nature of diabetic foot ulcers makes them difficult to manage and treat. A dynamic management plan is required to treat diabetic lower limb ulcerations. This involves a strategic approach, including mechanical offloading, wound debridement, wound dressing, patient education and surgical intervention. Alternative methods have been developed, of which phototherapy is one. Phototherapy, or low-level laser therapy (LLLT), is a therapeutic treatment modality that has been found to enhance wound healing. Its therapeutic properties have been determined by means of in vitro, in vivo and animal studies. Some studies have shown that the clinical application of phototherapy has a positive effect on the process of wound healing. Therefore, LLLT has the potential to decrease the level of secondary complications, improve wound regeneration, and ultimately improve patient quality of life. This review will discuss the concept of chronic wound management by means of LLLT in patients who suffer from type 2 diabetes.
