Beskrivelse
Inclusion Criteria:
- Medical diagnosis of Diabetes Mellitus type 1 or 2;
- Presence of a foot ulcer with duration ≥ 4 weeks, characterizing a chronic ulcer;
- Age ≥ 18 years;
- Ankle-brachial index compatible with adequate perfusion, allowing for the safe conduct of treatment;
- Wagner Grade I or Wagner Grade II classification of DM ulcer
- Ability to understand the objectives of the study and signature of the ICF (Informed Consent Form). -
Exclusion Criteria:
- Having more than one ulcer to be treated, regardless of etiology;
- Presence of hematological diseases that may interfere with peripheral blood analysis, such as: hemolytic anemias, hemoglobinopathies (sickle cell anemia), leukemias, lymphomas, multiple myeloma, or other blood dyscrasias that may significantly interfere with cell morphology or peripheral blood analysis;
- Active systemic infection at the time of enrollment;
- Active neoplasia undergoing treatment or under investigation;
- Use of immunosuppressants or corticosteroids;
- Pregnant or breastfeeding women;
- Use of photosensitizing medications;
- Allergy or sensitivity to any of the study interventions;
- Clinical signs of infection, necrosis, devitalized tissue, or wound colonization.
- Acute clinical conditions that contraindicate participation, whether related or unrelated to DM.

Application of transcutaneous PBM therapy to the foot ulcer Photobiomodulation (PBM)-formerly referred to as low-level laser therapy (LLLT) or cold laser therapy-is a non-invasive, non-thermal therapeutic modality that employs light in the red to near-infrared spectrum (typically spanning wavelengths from approximately 600 nm to 1,100 nm) to elicit beneficial biological responses in target tissues.

Tidsramme |
|---|---|---|
|
Size of wound area
Tidsramme: At the basal assessment (baseline), immediately before the PBM therapy, and 12 weeks of treatment
|
Wound area (cm²). To obtain the wound area, a standardized two-dimensional measurement technique will be used, considering the greatest length (longitudinal axis) and the greatest width perpendicular to the length (transverse axis), with area estimated using the formula: Area (cm²) = length × width This method is widely accepted in clinical practice and clinical studies, especially when combined with evaluator standardization and systematic photographic documentation, and is recommended by international guidelines for longitudinal wound monitoring (IWGDF, 2023; EWMA, 2022). |

Rate of area reduction over time
Tidsramme: At the basal assessment (baseline), immediately before the weekly PBM therapy. and 12 weeks of treatment

Healing Wound Progression
Tidsramme: At the basal assessment (baseline), and 12 weeks of treatment
|
The assessment of healing progression will be performed using the Pressure Ulcer Scale for Healing (PUSH), developed by Bryant & Nix in 1997 and validated by the National Pressure Ulcer Advisory Panel (NPUAP) (NPUAP, 1998; Bryant & Nix, 1997).

Pain Intensity
Tidsramme: At the basal assessment (baseline), immediately before the weekly PBM therapy, and 12 weeks of treatment
|
The presence of pain in the cutaneous reference region of the triceps surae will be assessed using a Numerical Pain Scale (NPS) / The NPS is an aid in measuring the intensity of pain felt by the patient, an important instrument to verify progress and analyze the treatment instituted.
The participant should be asked about their level of pain, where 0 means total absence of pain and 10 the maximum pain level.

Thermographic wound temperature
Tidsramme: At the basal assessment (baseline), and 12 weeks of treatment
|
Thermographic assessment will be performed using a portable infrared camera (FLIR C5) (Figure 3), with a spectral range of 7.5-14 µm (thermal infrared), thermal resolution of 160 × 120 pixels, sensitivity ≤ 0.05 °C (50 mK), and accuracy of ±2 °C or ±2%.
Emissivity was set at 0.98 for adequate representation of the skin surface.

Blood cell morphology
Tidsramme: At the basal assessment (baseline), and 12 weeks of treatment
