Laser application either before or after fatigue reduced the post-fatigue concentrations of serum lactate and CK. The results were more pronounced in the post-fatigue laser group.
In this study, we aimed to analyze the effects of low-level laser therapy (LLLT; 660 nm) on levels of protein expression of inflammatory mediators after cutting Achilles tendon of rats. Thirty Wistar male rats underwent partial incisions of the left Achilles tendon, and were divided into three groups of 10 animals according to the time of euthanasia after injury: 6, 24 and 72 h. Each group was then divided into control group and LLLT group (treated with 100 mW, 3.57 W cm(-2), 0.028 cm(2), 214 J cm(-2), 6 J, 60 s, single point). In LLLT group, animals were treated once time per day until the time of euthanasia established for each group. The group treated with LLLT showed a significant reduction of IL-1β compared with control groups at three time points (6 h: P=0.0401; 24 h: P=0.0015; 72 h: P=0.0463). The analysis of IL-6 showed significant reduction only in the LLLT group at 72 h compared with control group (P=0.0179), whereas IL-10 showed a significant increase in the treated group compared with control group at three experimental times (6 h: P=0.0007; 24 h: P=0.0256; 72 h: P<0.0001). We conclude that LLLT is an important modulator of inflammatory cytokines release after injury in Achilles tendon.
Introduction: Down Syndrome (DS) is a chromosomal abnormality characterized by mental retardation of varying degrees and is one of the most commonly found chromosomal aberrations, presenting motor delay such as muscular hypotonic, balance disorders, motor coordination and gait changes. Objective: To evaluate the functional capabilities in children with Down syndrome through the Pediatric Evaluation of Disability Inventory (PEDI). Methods: 20 children of both sexes, 10 with normal motor development (Control group) and 10 with Down syndrome. The functional capabilities were evaluated by PEDI (part I: functional capabilities, part II and III: caregiver assistance and change in environment) through interviews with caregivers. Results: Significant differences were observed in Part I, regarding functional capabilities in self-care (p = 0.0007), mobility (p = 0.0007) and social function (p = 0.0002), and in Part II, regarding caregiver assistance, the domains of self-care and mobility had p <0.0001 and p = 0.001. In Part III, changes in environment were more frequent when related to Down group. Conclusion: The Down syndrome group has lower functional performance in both functional capabilities and caregiver assistance, when compared to control group. However, it is clear that this questionnaire provides subsidies to make an early stimulation treatment in order to perform daily skills with the least possible help from their caregivers.
Neste estudo, o objetivo foi analisar, do ponto de vista quantitativo, as possíveis alterações da marcha de 11 pacientes (oito do sexo masculino e três do sexo feminino), idade média de 61,7±16,4 anos, com diagnóstico clínico de AVE. Foram investigadas as seguintes variáveis: base de suporte, comprimento do passo e comprimento da passada, por meio do método de impressão plantar, em uma distância de 5 metros. Houve ausência de significância entre idade e base de suporte, idade e comprimento do passo e base de suporte e comprimento do passo. Os resultados da análise comparativa entre o comprimento da passada do pé esquerdo e pé direito não evidenciou diferença significante (p = 0,338), e a base de suporte encontrou-se aumentada na maioria dos sujeitos, havendo redução do comprimento do passo e da passada.
Introdução: A limitação da amplitude de movimento de dorsiflexão é o parâmetro mais utilizado na avaliação e evolução da abordagem fisioterapêutica. Objetivos: Avaliar a confiabilidade e aplicabilidade da goniometria e do teste Weight-Bearing para a mensuração de dorsiflexão do tornozelo. Método: Participaram 25 voluntários, do sexo masculino, com idade média de 38,81 (± 6,26), distribuídos em dois grupos: G1 (n=13 Não-atleta) e G2 (n=12 Atletas). A medida da dorsiflexão do tornozelo foi realizada com goniômetro universal adaptado com haste metálica de 45 cm e por meio do teste Weigth-Bearing. Os dois métodos foram aplicados nos participantes por três examinadores, cada um efetuando a mensuração seis vezes. Com o ICC, verificou-se a confiabilidade dos testes. Resultados: Obtiveram-se ICC de 0,98 na goniometria, para o G1, e 0,97, para o G2. Já para o Weight-Bearing, obteve-se ICC de 0,98 para o G1 e o mesmo para o G2. Todas essas medidas foram consideradas muito elevadas. Conclusão: Ambos os métodos são de alta confiabilidade para aplicação clínica nessas condições experimentais.
