“…In the present study, pulsed ultrasound obtained better results for thermal hyperalgesia, corroborating the research by Coradini et al 28 who compared photobiomodulation and ultrasound in formalin-induced acute knee pain in Wistar rats, both studies used the same ultrasound parameters. The authors concluded that both therapeutic modalities showed antinociceptive effects, although ultrasound was superior to photobiomodulation by laser.…”

“…One of the main characteristics of pathological pain is hypersensitization, i.e., changes in the plasticity of the nervous system, which occurs peripherally through reduction of the threshold for the activation of nociceptors, or centrally through the increased responsiveness of the spinal cord to sensorial stimuli 16,27 . A study conducted by Andrade et al 10 evaluated the effect of LLLT regarding hyperalgesia and spontaneous nociception in animals subjected to CCI surgery; after 12 weeks of treatment, reduction in hyperalgesia and promotion of analgesia were observed, and the animals returned to the pre-surgical state.…”

“…The discussions on LLLT for the control of various types of pain has been gaining prominence in the literature, with great emphasis on neuropathic pain 15,16 . A significant amount of studies using this therapy is observed; however, the parameters used are quite disparate, hindering the establishment of appropriate protocols to ensure the effectiveness of LLLT 17 .…”

Eficácia da terapia a laser de baixa intensidade no controle da dor neuropática em camundongos

2018

RESUMO A terapia a laser de baixa intensidade (LLLT) vem sendo amplamente discutida na literatura como forma alternativa de tratamento para diversos tipos de dor, com destaque para a neuropática. Essa terapia sobressai pelo fato de não ser invasiva, raramente causar efeitos colaterais e ser de baixo custo. Em contrapartida, para sua eficácia, é necessário o detalhamento dos parâmetros, que ainda são muito discrepantes na literatura. Assim, este trabalho tem como objetivo investigar o efeito da LLLT, na faixa do infravermelho, com fluência de 30J/cm², no controle da dor neuropática em modelo animal. Foram utilizados 24 camundongos da cepa suíço albino, machos, pesando 2530 gramas, divididos em três grupos: Grupo Placebo (GP), Grupo Laser (GL30) e Grupo Sham (GS). A indução da neuropatia foi feita através do modelo de constrição crônica do nervo isquiático (CCI), e o tratamento da LLLT realizou-se da seguinte maneira: GP com o laser com fluência de 0J/cm2, GL30 tratado com fluência de 30J/cm2, e GS com simulação de cirurgia sem intervenção. Executaram-se as irradiações 3 vezes por semana, durante 90 dias, no ponto de compressão do nervo, utilizando-se a técnica de contato. A fins de avaliação, foram utilizados o teste da placa quente, para hiperalgesia térmica, e o Teste de Randall-Selitto para hiperalgesia mecânica. Nos resultados do GP, observamos que não houve melhora significativa nos dias após a cirurgia em nenhum dos testes realizados e, no GL30, observou-se uma melhora expressiva em ambos os testes a partir do 30º dia de tratamento para o teste de Placa Quente e a partir do 45º para o Randall-Selitto, em que os camundongos apresentaram restauração total da sensibilidade. Concluímos, pois, que a utilização de LLLT com fluência de 30J/cm2 no tratamento da dor neuropática em modelo animal é eficaz.

Evaluation of the therapeutic effects of led (λ627 ± 10 nm) on the initial phase of ankle sprain treatment: a randomised placebo-controlled clinical trial

et al. 2018

Various therapies for the treatment of sprains have emerged as advances occur in biomedical engineering and photobiology. Therapy with coherent and non-coherent light is a treatment modality for various musculoskeletal injuries. The main certified phototherapy benefits are the reduction of nociceptive processes and the modulation of the inflammatory process, among others. The objective of this study was to analyse the changes caused by the use of light-emitting diodes (LED) (λ627 ± 10 nm) with an energy density of 10 J/cm in 40 subjects divided into two groups (20 placebo and 20 LED). All of the volunteers had acute ankle sprains by inversion of grade II treated with the PRICE (protection, rest, ice, compression and elevation) technique and were treated for 6 days with LED therapy and LED therapy turned off (placebo). Pain assessment was performed on the 1st, 3rd and 6th days using the visual analogue scale (VAS) of pain, the McGill Pain Questionnaire and volumetry. The group treated with LED showed statistically decreased pain compared to the placebo group in both the VAS (85.79 vs 55.73%) and McGill questionnaire (83.33 vs 52.52%). The reduction of oedema in the LED group on the 3rd and 6th days after therapy was statistically superior to that in the placebo (p < 0.0001). Based on the results of this study, treatment with LED, using the tested dose, is effective for pain and oedema in the initial phase of ankle sprains.
