Interventions

This is an exploratory, randomized, controlled, double-blind clinical trial with four parallel arms. Participants will be randomly assigned to four groups: a control group (n = 5), receiving conventio

Group 1 (n = 5), receiving conventional treatment combined with low-level laser therapy at an energy of 0.5 J per point

Group 2 (n = 5), receiving conventional treatment combined with low-level laser therapy at an energy of 1 J per point

and Group 3 (n = 5), receiving conventional treatment combined with low-level laser therapy at an energy of 2 J per point, totaling 20 participants. Laser therapy will be administered once a week for

s double-blind design. The randomization sequence will be generated beforehand using a spreadsheet created in Numbers software. Twenty random numbers will be generated using the random function and ar

Design outcomes

Primary

Measure	Time frame
To assess the reduction in wound healing time using serial evaluation via the Bates-Jensen Wound Assessment Tool (BWAT) scale and measurement of the wound with a two-dimensional ruler, and from this, to observe if there was a progressive decrease in size and the time required for complete healing	—

Secondary

Measure	Time frame
To establish a clinical protocol for the treatment of venous lesions based on scientific evidence regarding the efficacy of low-level laser therapy and the optimal power level to be applied, using a comparison between randomized groups through observation of differences in scores on the Bates-Jensen Wound Assessment Tool (BWAT) scale, healing time, and clinical evolution of the lesions;Evaluate the reduction in pain, exudate volume, and dressing change frequency using the Numerical Visual Scale (NVS) to measure pain, assess exudate volume by saturating the primary dressing, and record the need for dressing changes, observing reductions in Bates-Jensen Wound Assessment Tool (BWAT) scores and decreased dressing change frequency	—
