About

This study seeks to evaluate the effect of photobiomodulation (PBM) in the prevention of Diabetic foot (DF), in patients at moderate and high risk for its development, through a controlled, randomized, double-blind clinical trial. Individuals between 18 and 75 years old of both sexes, with type 2 diabetes mellitus (DM), and moderate and high risk for DF will be randomized and allocated into 2 groups of 32 participants each. The PBM Group will use a boot with 1344 LEDs, 504 of which are 660 nm located on the sides of the boot (28.5 milliwatt, 10 J per LED); 504 850 nm also located on the sides of the boot (23 milliwatt, 8 J per LED); 168 of 660 nm located at the base of the boot (28.5 milliwatt, 10 J per LED); 168 of 850 nm also located at the base of the boot (23 milliwatt, 8 J per LED) once a day for 6 minutes, for 60 days and will receive therapeutic education. Participants will be evaluated at baseline, after 30 days (clinical examination) and after 60 days (clinical examination, Peripheral Neuropathy (PN) assessment, Peripheral Artery Disease (PAD) assessment, blood and urine tests, and quality of life).

Full description

Diabetic foot (DF) prevention involves risk classification, systemic care, assessment of Peripheral Artery Disease (PAD) and Peripheral Neuropathy (PN), regular foot examination, therapeutic education, and routine use of appropriate footwear. Photobiomodulation (PBM) has been successfully applied in the healing of DF. In addition to the therapeutic effects of PBM, its preventive effects have attracted the attention of researchers. This study seeks to evaluate the effect of PBM in the prevention of DF, in patients at moderate and high risk for its development, through a controlled, randomized, double-blind clinical trial. Individuals between 18 and 75 years old of both sexes, with type 2 DM, and moderate and high risk for DF will be randomized and allocated into 2 groups of 32 participants each. The PBM Group will use a boot with 1344 LEDs, 504 of which are 660 nm located on the sides of the boot (28.5 milliwatt, 10 J per LED); 504 850 nm also located on the sides of the boot (23 milliwatt, 8 J per LED); 168 of 660 nm located at the base of the boot (28.5 milliwatt, 10 J per LED); 168 of 850 nm also located at the base of the boot (23 milliwatt, 8 J per LED) once a day for 6 minutes, for 60 days and will receive therapeutic education. Participants will be evaluated at baseline and after 30 days (clinical examination) and 60 days (clinical examination, PN assessment, PAD assessment, blood and urine tests, and quality of life). The collected data will be stored, and organized in a repository and the appropriate statistical tests will be applied for each specific analysis. In all tests, a significance level of 5% will be adopted.
