Objetivo: Analisar os efeitos imediatos e tardios da aplica??o do Kinesio Taping (KT) na atividade eletromiogr?fica do m?sculo vasto medial obl?quo (VMO), no desempenho isocin?tico do quadr?ceps femoral e na dor de sujeitos portadores da SDFP. M?todos: Ensaio cl?nico, randomizado e cego, no qual 54 volunt?rias, com idade m?dia de 23,70 ? 3,76 anos, foram distribu?das aleatoriamente em tr?s grupos e realizaram um dos seguintes protocolos: (1) grupo controle - permaneceram em repouso; (2) grupo com tens?o - aplica??o do KT com tens?o na regi?o do VMO; (3) grupo sem tens?o - aplica??o do KT sem tens?o, na mesma regi?o. Todas as volunt?rias foram submetidas ? avalia??o da intensidade da dor, da atividade eletromiogr?fica do VMO e VL e dos par?metros dinamom?tricos em tr?s momentos distintos: antes da aplica??o do KT, imediatamente ap?s e 72h depois da aplica??o. A an?lise estat?stica foi realizada por meio do SPSS (vers?o 20.0). Foi utilizada uma ANOVA de modelo misto para verificar diferen?as intra e intergrupo, com n?vel de signific?ncia de 5% (p ? 0,05). Resultados: Houve diferen?a significativa intergrupo na intensidade da dor entre o grupo sem tens?o e o grupo controle, ap?s 72h. Com rela??o ?s vari?veis dinamom?tricas, n?o houve diferen?a entre os grupos avaliados para o pico de torque normalizado pelo peso corporal, pico de torque m?dio, pot?ncia m?dia e trabalho total. Tamb?m n?o foram observadas diferen?as no que se refere ?s vari?veis eletromiogr?fica: raz?o VMO/VL e tempo de in?cio da ativa??o do VMO em rela??o ao VL, em cadeia aberta e fechada. Conclus?o: O Kinesio Taping, aplicado no vasto medial obl?quo, n?o promove altera??es imediatas e nem tardias no desempenho isocin?tico nem nos par?metros eletromiogr?ficos de portadores da S?ndrome da Dor Femoropatelar. Entretanto, foi observada uma redu??o da dor no grupo que aplicou o KT sem tens?o, ap?s 72 horas da sua aplica??o. / Patellofemoral pain syndrome (PFPS) is defined as anterior or retropatellar pain. It is one of the most frequent musculoskeletal dysfunctions in the knee, that affects mainly, the female population and whose treatment is controversial. Objective: To analyze the immediate and late effects of Kinesio Taping (KT) in the electromyography activity of the vastus medialis obliquus (VMO), in the isokinetic performance of the quadriceps femoris and the pain of subjects with PFPS. Methods: Randomized clinical trial, in which 54 volunteers, with a mean age of 23.70 ? 3.76 years were randomized into three groups and performed one of the following protocols: (1) control group - remained in rest; (2) group with tension - application of KT with tension in the VMO region; (3) group without tension - application of KT without tension, in the same region. All volunteers were submitted to the evaluation of pain intensity, electromyography activity of the VMO and the VL and the dynamometric parameters in three different moments: before the application of KT, after the application and 72 hours after the application. Statistical analysis was performed using SPSS (version 20.0). A mixed model ANOVA was used to verify intra and intergroup differences, with a significance level of 5% (p ? 0.05). Results: There was a significant intergroup difference in pain intensity in the 72h evaluation between the no tension group and the control group. Dynamometric variables, peak torque normalized by body weight, mean peak torque, mean power and total work did not show significant difference between the groups evaluated. No differences were observed in the electromyography variables, VMO/ VL ratio and time of onset of VMO activation in relation to VL. Conclusion: Kinesio Taping, applied to the vastus medialis obliquus, does not promote immediate or late changes in the isokinetic performance and in the electromyography parameters of patients with Patellofemoral Pain Syndrome. However, was observed a reduction in pain, in the no tension group after 72 hours of application.

M?todos: Tratou-se de um estudo observacional, transversal e comparativo. A amostra foi composta por 18 indiv?duos alocados em dois grupos distintos: Grupo DPOC (GD) e Grupo Saud?veis (GS) que foram avaliados atrav?s da fun??o pulmonar; do desempenho neuromuscular do quadr?ceps; os marcadores bioqu?micos do dano e fadiga muscular; fatigabilidade e dor muscular. Os dados foram analisados com o software Statistical Package for the Social Sciences (SPSS) vers?o 20.0 com n?vel de signific?ncia de 5%. Resultados: Observou-se diferen?a estatisticamente significante na pot?ncia entre o GD e GS (99,0 vs 145,1; p=0,02) e uma tend?ncia ? diferen?a no trabalho total, respectivamente (1.035,5 vs 1.671,5; p=0,06) entre os grupos. Na an?lise do marcador bioqu?mico, o LDH, para fadiga muscular foi observado diferen?a significativa entre os grupos imediatamente ap?s o teste isocin?tico no quadr?ceps (402,3 vs 289,4; p=0,03). Conclus?es: As respostas neuromusculares e bioqu?micas do dano e fadiga muscular do quadr?ceps femoral no DPOC apresentam-se diminu?da na popula??o estudada. / Objective: To compare neuromuscular and biochemical responses of femoral quadriceps muscle damage and fatigue among COPD and healthy individuals. Methods: This was an observational, cross-sectional and comparative study. The sample consisted of 18 individuals allocated to two distinct groups: COPD Group (GD) and Healthy Group (GS) who were evaluated through lung function; of the neuromuscular performance of the quadriceps; The biochemical markers of muscle damage and fatigue; fatigue and muscle pain. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 20.0 with a significance level of 5%. Results: There was a statistically significant difference in the power between GD and GS (99.0 vs 145.1; p = 0.02) and a tendency to the difference in total work, respectively (1,035.5 vs 1,671.5; p = 0.06) between groups. In the analysis of the biochemical marker, LDH, for muscle fatigue was observed a significant difference between the groups immediately after the isokinetic test in the quadriceps (402.3 vs 289.4; p = 0.03). Conclusions: The neuromuscular and biochemical responses of femoral quadriceps muscle damage and fatigue in COPD are diminished in the study population.
