The experimental group received red light to the lesion and infrared light around it, while the sham group received a simulation. We assessed pain with the NRS and Short\u2010Form McGill Pain Questionnaire (SF\u2010MPQ); tissue healing with the REEDA scale (Redness, Edema, Ecchymosis, Discharge, Approximation) at baseline, 30\u2009min (primary outcome), and 12\u201336\u2009h after intervention and satisfaction with a Likert scale 7\u201310\u2009days post\u2010intervention.

Analysis of variance revealed no significant interaction between time and group at any time point evaluated. Of the participants, 84.09% were satisfied or very satisfied with the intervention.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Although both groups experienced a reduction in pain after the intervention, a single PBM application with these parameters was not superior to a sham treatment.
