Efeito da fotobiomodulação laser na cicatrização de feridas

Abstract

Skin wounds are illnesses present in the current context and the treatments most frequently used range from surgical processes, the use of medications, and electrophototherapy resources. Low Intensity Laser Therapy (LTBI) photobiomodulation promotes acceleration in ATP synthesis, increase in cellular function, especially lymphocytes, macrophages and fibroblasts, thereby influencing the healing process of skin wounds. The study investigated the effect of Low Intensity Laser Therapy (LTBI) on patients with skin wounds. This is a pilot study of a double-blind randomized clinical trial. The study was divided into (3) three groups: control, placebo, LTBI. The allocation of participants to the respective groups was carried out randomly. LTBI treatment was applied daily for 10 sessions, while the control group received no intervention, only monitoring. Pre- and post-treatment photographs were taken at all sessions, and the wound area was measured using ImageJ software. The results showed a trend towards reduced wound size in patients treated with LTBI compared to the control and placebo groups. It was concluded that LTBI, in the configurations used, can have benefits in the treatment of skin wounds, resulting in an improvement in patients' quality of life. However, additional studies with a larger number of participants are needed to confirm these results.
