Relevance – Studies have shown that laser irradiation favors regeneration of skeletal muscle, shortening inflammatory phase and accelerating proliferative and maturation phases of skeletal muscle regeneration.

Compared 10 and 50 J/cm 2 fluences 7, 14, and 21 d after cryolesion on TA through morphology and muscle tissue structure analysis. Inflammatory process, granulation tissue, tissue structure, number of blood vessels, and immunomarkers were evaluated histologically and by immunohistochemistry analysis.

Earlier recruitment of cell infiltrate Higher amount of newly formed muscle fiber. More organized muscle tissue structure at the lesion.
