Brief summary

Diabetic foot ulcers (DFU) are among the late complications of DFU, defined as skin lesions that involve the dermis to deeper structures, such as muscles and bones. Although preclinical studies have demonstrated the effects of GaAs 830 nm in diabetic wounds, no clinical studies have been performed, revealing the need for more in-depth analyses to identify the effects and ideal parameterization of PBM with GaAs 830 nm wavelength in the treatment of diabetic ulcers, improving quality of life, as well as to understand the therapeutic feasibility, time required for healing and recurrence rates of these lesions. Experimental, randomized, controlled, double-blind study, with blinding applied to the evaluator and participants. A total of 136 volunteers will be recruited for the research, carried out at the Integrated Center of Medical Specialties (CIEM) - Polyclinic. LLLT GaAs 830nm will be used with three dosages of low, medium and high intensity (4 J/cm², 8 J/cm², 12 J/cm²). The study will have three intervention groups using LLLT with GaAs 830nm and a control group, in which LLLLT will be performed with a GaAs 904nm wavelength and a dose of 10 J/cm², according to Saura et al (2024). This study was approved by the local Research Ethics Committee (Opinion 7,488,044), conducted in accordance with the Declaration of Helsinki and in accordance with the CONSORT (Consolidated Standards of Reporting Trials) guidelines.

Design outcomes

Primary

MeasureTime frameDescription
Ulcer area reduction ratePre-intervention, five weeks and ten weeks of treatmentThe ulcers will be measured with a paper ruler and photographed for later analysis of the images using the ImageJ program. The paper ruler will be positioned to measure the length and width of the ulcers.

Secondary

MeasureTime frameDescription
University of Texas RankingsPre-intervention, five weeks and ten weeks of treatmentFor analysis of ulcer depth, volunteers will be grouped into A1 and C1 (superficial ulcers), A2 and C2 (ulcers involving tendon or joint capsule) and A3 (ulcers involving bone).
Quality of life assessmentPre-intervention, five weeks and ten weeks of treatmentThe EQ-5D tool will be used, consisting of five questions that assess the following aspects: mobility, personal care, usual activities, pain or discomfort, and anxiety/depression.
Glycemic level assessmentOnce a week for ten weeks (20 sessions)Volunteers' blood glucose levels will be checked once a week throughout treatment.
Analysis of healing time and recurrence rateQuarterly follow-up (3 months) after initial healingHealing time:Difference, in days, between the date of the first clinical record of the lesion and the date on which the wound is considered fully healed, characterized by complete epithelialization, absence of secretion and necrotic tissue.Recurrence: assessed based on the difference, in days, between the date of complete healing and the record of recurrence of the lesion in the same region, major amputation, death or the end of the study period.
