“…The LLLT has been shown to be a noninvasive physical therapy modality with analgesic, tissuehealing, myorelaxant, fibroblast-proliferating, ligamentrepairing and anti-inflammatory effects that are induced nonthermally and nondestructively [16], [24]- [27]. The clinical results from many previous studies suggest that the LLLT application may be a successful method of pain control in musculoskeletal disorders [28]- [34].…”

The aim of our study was to evaluate the immediate effects of an 830-nm Aluminium gallium arsenide (GaAlAs) laser, by examining the changes, in pressure-pain threshold (PPT) and tenderness at 3 kg of the myofascial trigger point (MTrP) of the upper trapezius muscle in visual display terminal (VDT) workers in comparison with placebo treatment. Thirty VDT workers (13 males, 17 females) with complaints of upper trapezius muscle were recruited. All participants were given either active GaAlAs laser (830 nm wavelength, 450 mW, 9 J at point) or placebo GaAlAs laser, according to the double-blinded and placebo-controlled trial. Both active and placebo low-level laser therapy (LLLT) treatments showed no significant effect on PPT and tenderness at 3 kg. These results suggest that a higher dosage may be necessary to produce immediate effects when applying LLLT to the MTrP of relatively large muscles such as the upper trapezius muscle.

“…It is widely used in controlling inflammatory processes, repair of skin wounds, rheumatic diseases, osteoarthromyopathies, neuromuscular disorders, sports injuries, among others. [10][11][12][13][14] Although LLLT is widely used in clinical rehabilitation, there are conflicting results in the literature, [15][16][17][18][19][20][21] and we believe that investigating the cellular and molecular events that occur when lasers of different wavelengths interact in myopathies, could result in a significant contribution to optimizing its use in inflammatory muscle diseases. We set out to investigate the photobiomodulator effect of HeNe and GaAs lasers, in an experimental model of myopathy, identifying the inflammatory biomarker, nitric oxide (NO), associated with oxidative stress, and analyzing any anatomopathological changes.…”

Purpose:The aim of the present work was to study the effect of Helium-Neon (HeNe) and Gallium Arsenide (GaAs) laser upon nitric oxide (NO) plasma levels, an inflammatory biomarker associated with oxidative stress, in rats with experimental myopathy. These were evaluated through histological assessment. Materials and Methods: The groups studied were: (A) control (intact rats that received LLLT sham exposures), (B) rats with myopathy and sacrificed at 24 h later, (C) rats with myopathy and sacrificed 8 days later, (D) rats with myopathy and treated with HeNe laser, (E) rats with myopathy and treated with GaAs laser, (F) intact rats treated with HeNe laser and (G) intact rats treated with GaAs laser. Myopathy was induced by injecting 50µl of 1% carrageenan λ (type IV) in the left gastrocnemius muscle. Low Level Laser Therapy (LLLT) was applied with 9.5 J.cm -2 daily for 10 consecutive days with each laser. The determination of the NO was made by spectrophotometry. The muscles were stained with HematoxylinEosin and examined by optic microscopy. Quantitative variables were statistically analyzed by the Fisher test, and categorical by applying Pearson's Chi Squared test at p <0.05 for all cases. Results: In groups B and C, NO was significantly increased compared to groups A, D, E, F and G (p<0.05). In group C, the percentage of area with inflammatory infiltration was significantly increased compared to the other groups (p<0.001). Conclusions: LLLT decreased plasma levels of NO in rats with experimental myopathies and significant muscle recovery.

“…Também, os "laseres" terapêuticos de baixa potência não produzem efeito térmico (BAPTISTA, 2003;CHAVANTES;TOMIMURA, 2009a O laser da faixa espectral vermelha age na biorregulação das organelas e o da faixa infravermelha, na membrana celular alterando sua permeabilidade e a da membrana mitocondrial resultando, como já dito, na elevação do nível celular do ATP. Portanto, o LBI tem importante ação analgésica, antiinflamatória e de restauração tecidual, sendo considerado um valioso recurso terapêutico no tratamento de feridas, por seu poder cicatrizante (COLLS CRUAÑES, 1994;BALDAN, 2005;SHIMON, 2006;SORIANO et al, 2006;CHAVANTES;TOMIMURA, 2009b).…”
