Comparative study of laser action GaAlInP and high-frequency generator in the treatment of skin wounds in rats: an experimental study

Abstract

Introduction: Physiotherapy uses various treatments to accelerate the healing process, using laser radiation and high-frequency generator. Objective: To evaluate the action of laser GaAlInP and generator high frequency in the treatment of skin wounds. Methods: We performed a skin wound in 24 rats using a punch with 8 mm diameter. After, the animals were divided into four groups: Group A, control; B, Laser GaAlInP; C, high-frequency generator, and D, Laser GaAlInP + High-Frequency Generator being the GaAlInP laser (670 nm, 6 J/cm², 120/2) and the generator of high frequency (intensity of 80%, 120/2). Results: There was significance (P <0.05) between groups B and C compared with group A, giving emphasis to the group D, which revealed the P <0.01, showing a markedly significant when compared to this control. Conclusion: We conclude that the combination therapy (GaAlInP laser + high-frequency generator) was effective for short cicatrical process.
