Item Photobiomodulation and amniotic membrane for treat tendon injury in rats(Academia Brasileira de Ciências) Nicodemo, Mariana de Castro; Arisawa, Emilia Angela Lo Schiavo; Sant’Anna, Luciana Barros; Martins, Rodrigo Álvaro Brandão LopesTendons, complex fibrous structures, are subjected to great tensions, which can give rise to the so-called tendinopathies. This study aimed to evaluate photobiomodulation and human Amniotic Membrane applied as single or combined therapies to treat induced Achilles tendon lesions. Seventy-five rats were divided into five groups (n=15): C- control Sham surgery; I- tendon injury; LA- tendon injury treated with photobiomodulation; AM- tendon injury treated with Amniotic Membrane; LAM- tendon injury + photobiomodulation and Amniotic Membrane, subdivided into three groups (n=5) with analysis at 3, 7, and 14 days. The tendon injuries were made with a 20 g weight released from a mini guillotine onto the ankle in dorsiflexion. AM and LAM groups received an Amniotic Membrane fragment while LA and LAM groups received transcutaneous photobiomodulation, using a 660 nm wavelength laser. The inflammatory cells showed statistical differences between groups C and I (p<0.05), I and AM (p<0.01), I and LA (p<0.05), and I and LAM (p<0.01). Both photobiomodulation and Amniotic Membrane were shown to enhance tendon repair, and the association of photobiomodulation plus Amniotic Membrane was the most effective treatment. We conclude that the association of photobiomodulation plus Amniotic Membrane was effective in accelerating and improving the tendon regeneration process.Item Avaliação comparativa da distância percorrida, da função pulmonar e da qualidade de vida após reabilitação cardiorrespiratória com e sem fotobiomodulação transcraniana em indivíduos com espasticidade – Estudo piloto(CDRR Editor) Pinto, Ana Paula; Lemos, Sergio Luiz; Fagundes, Alessandra de Almeida; Martins, Rodrigo Álvaro Brandão Lopes; Neves, Marcele Florêncio das; Lima, Fernanda Pupio Silva; Lima, Mário OliveiraO objetivo do estudo foi avaliar os efeitos da reabilitação cardiorrespiratória (RC) isolada e associada a fotobiomodulação transcraniana (Ft) na distância percorrida (DP), função pulmonar e qualidade de vida de indivíduos com espasticidade. Os participantes foram alocados em dois grupos: Grupo fotobiomodulação transcraniana (GF, RC + Ft ativa, n=8) e Grupo placebo (GP, RC + Ft simulada, n=7). A RC consistiu em 12 semanas de tratamento, 2x semana por 1 hora, incluindo exercícios aeróbicos, respiratórios e resistidos de membros inferiores. Para Ft utilizou-se o cluster de laser (λ= 680 nm e 3 Lasers no λ= 808 nm, energia total de 36 J/ponto) nos pontos F7, F8, AFz. Foram avaliadas a DP, espirometria, manovacuometria e SF-36 na avaliação basal e reavaliação com 8 e 12 semanas. A DP aumentou em 165,43 metros e 222,46m em 12 semanas para GF e GP, respectivamente, com diferenças estatísticas intragrupos (p<0,05) e sem diferença intergrupos (p>0,05). Observou-se aumento no índice pico de fluxo expiratório apenas no GF na análise basal x12 semanas (p<0,05). O GF apresentou aumento da PImax e PEmax em 20% (8 semanas) e 15% (12 semanas). No SF-36, a diferença em relação ao basal, verificou-se os domínios aspectos físicos e dor para o GF comportamento de crescimento, e para o GP de decréscimo. Concluiu-se que a DP melhorou no GF e GP pós-intervenção, sem efeito potencializador do desempenho no GF e que a Ft parece ter influenciado na mecânica respiratória do GF e nos aspectos físicos e dor do SF-36.Item Transcranial photobiomodulation therapy associated with cardiorespiratory rehabilitation in spastic subjects(Springer Nature Link) Pinto, Ana Paula; Lemos, Sergio Luiz; Fagundes, Alessandra de Almeida; Neves, Marcele Florêncio das; Martins, Rodrigo Álvaro Brandão Lopes; Silva, Fernanda Pupio; Silva, Mário OliveiraThe objective of this study was to evaluate the effects of cardiorespiratory rehabilitation (CR) and transcranial photobiomodu- lation (tPBM) on exercise tolerance (ET), heart rate variability (HRV), and peripheral muscle activity in individuals with spasticity. Fifteen participants with spasticity were randomly assigned to two groups: the tPBM group (tPBMG) consisted of eight volunteers who underwent tPBM (on mode) and CR, while the control group (CG) consisted of seven volunteers who underwent simulated tPBM (off mode) and CR. The CR program included 12 weeks of treatment, twice a week for one hour, involving aerobic exercises and lower limb strengthening. For tPBM, a cluster with three lasers (λ = 680 nm, 808 nm), with a power of 100 mW/laser and energy of 36 J, applied to the F7, F8, and Fpz points. The following parameters were evalu- ated after 8 and 12 weeks: ET, HRV, and surface electromyography (EMG) of the rectus femoris muscle during orthostasis (ORT), isometric squatting (ISOM), and isotonic squatting (ISOT). Both groups showed a 40% increase in ET for the CG and a 30% increase for the tPBMG. The CG had more pronounced parasympathetic modulation alterations during post-exercise effort and recovery compared to the tPBMG. The EMG results showed that the tPBMG exhibited progressive improvement in muscle activity during ISOM and ISOT, as well as a decrease in the interlimb difference. In conclusion, both CR and tPBMG demonstrated improvements in ET. However, tPBMG specifically showed promising effects on HRV modulation and peripheral muscle electrical activity, providing additional benefits compared to CR alone.
