Brief Summary

Diabetic foot ulcers (DFU) are aggressive complications of diabetes mellitus (DM) and affect 25% of these patients. DFU are associated with a high risk of amputations and early mortality and significantly impact quality of life (QoL). The low-level laser therapy (LLLT) is an important approach for the treatment of DFU, however there is a lack of data on its influence on the QoL of patients with DFU. On the other hand, adherence to self-care is a factor closely related to QoL. Therefore, this study is justified by the need to understand the impact of LLLT on QoL and its relationship with self-care. Aim: To evaluate the quality of life of patients with diabetic foot ulcers treated with different doses of LLLT (GaAs) 904 nm and its association with aspects of adherence to self-care. Methods: This is a randomized, double-blind, placebo-controlled clinical trial. Participants will be randomly assigned to the groups: control LLLT placebo (CG), LLLT 904 nm 10 J/cm² (LG1), LLLT 904 nm 8 J/cm² (LG2) and LLLT 904 nm 4 J/cm² (LG3). QoL data, percentage of healing and pain will be assessed before the start of the intervention, in 10th week and after one month to the end of intervention, self-care will be assessed before the start of the intervention and at the end of intervention. Eighty participants with DFU will be recruited who will receive intervention twice a week for up to 20 visits (10 weeks).
