Effect of Photobiomodulation as a Preventive Treatment for Diabetic Foot

The PBM Group will use a boot with 1344 LEDs, including 504 LEDs of 660 nm located on the sides of the boot (28.5 mW, 10 J per LED); 504 LEDs of 850 nm also located on the sides of the boot (23 mW, 8 J per LED); 168 LEDs of 660 nm located at the base of the boot (28.5 mW, 10 J per LED); and 168 LEDs of 850 nm also located at the base of the boot (23 mW, 8 J per LED) once daily for 6 minutes, over 60 days.

The Control Group will use a non-therapeutic LED boot (sham procedure) for 6 minutes once daily for 60 days. The boot used is identical to the active boot, but there is no light emission.

Participants will receive therapeutic education regarding nutrition, foot examination, self-care, and guidance on physical activity.
