Abstract: RESUMO: Os nervos periféricos sofrem constantes lesões de origem traumática, o que resulta em perdas funcionais. A terapia com laser de baixa potência vem sendo utilizada para minimizar os efeitos maléficos da inflamação e acelerar o processo de cicatrização dos tecidos lesados. Este estudo teve como objetivo verificar o efeito da irradiação do laser 830 nm no comportamento do nervo isquiático de ratos submetido a esmagamento. Foram utilizados 20 ratos, todos tendo tido o nervo isquiático esmagado, divididos e… Show more

“…However, Alcântara et al 23 using much higher energy density (60 J/cm 2 ), 660 nm, in 2 points, 24 hours after a sciatic nerve crush model for rats, observed that the LLLT induced the modulatory effect on inflammation. In contrast, Gonçalves et al 6 using a dosage similar from our study (4 J/cm 2 ), also found that the LLLT (830nm) application for sciatic nerve regeneration during 14 consecutive days generated significantly less inflammatory infiltrate and significantly greater amount of fibroblasts compared to placebo. Thus, one can assume that the lack of results of the present study related to LLLT, regarding nerve regeneration, may be due to its small dosage, as it was applied only once per session, and the delay to start the treatment.…”

“…3 Several types of treatments for peripheral nerve injury are established or tested 4,5 and the physical therapy resources are usually used with regenerative purpose and for the relief of symptoms. The Low-Level Laser Therapy (LLLT) 6 and neural mobilization, 7 as examples, target on effective recovery function during rehabilitation. 8 The LLLT acts as moderator of the local inflammatory reaction in the early stages of tissue injury, thus assisting the inflammation and pain reductions.…”

“…However, even though numerous studies confirm the laser biomodular capacity, the parameters and the ideal protocols for its application haven´t been established yet 3,[11][12][13][14] . That reinforces the necessity of new studies with the objective to accomplish a better suitability of the parameters and protocols for each application.…”

“…Gonçalves et al 47 verificaram os efeitos da irradiação do laser 830 mn na regeneração do nervo isquiático de ratos submetido a esmagamento e concluíram que contribuiu para a redução do processo inflamatório, tendo verificado menor degeneração da bainha de mielina e menos infiltrado inflamatório. Estudos que utilizaram o laser de baixa intensidade na regeneração de lesão nervosa periférica apresentam variação na energia utilizada, de 0,086 J até 105 J; foram feitos em células isoladas e em experimentação em animais.…”
