Abstract. The purpose of this study was to evaluate the compound nerve action potential amplitude and latency measured to determine the degree of myelination and thenumber of fibers stimulated in a model of stimulated frog sciatic nerve laser at 810 nm as perioperative treatment after injury. It used 30 bullfrogs (Rana catesbeiana) to obtain 60 sciatic nerves formingfour groups, groups 1 and 2 worked with nerves in vitro, were dissected in humid chambers for placing isolated organ, was recorded on compound nerve action potential, the second group laser wasapplied at 24, 48, 72, 96 and 120 hours and at the same time were placed in 10% formalin. Groups 3 and 4 are worked in vivo localizing the nerve and causing damage through compression, occurred over thecompound nerve action potential to assess the degree of myelination and the number of fibers stimulated, the group 4 was applied to 810nm laser (500Hz , 10J, 200 mW) after injury, after 48 hours, three...
