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.

MATERIALS AND METHODS: This is a controlled clinical trial, randomized and double blind. Sixty healthy volunteers (23.6 ? 4.2anos; 54.2 ? 7.7kg, 1.62 ? 0.009 cm) of both sexes were divided randomly into three groups: control group (CG), experimental group 1 (SG1) with application of the current Russian 30 HZ and experimental group 2 (EG2) at 70 Hz The volunteers performed an initial assessment (AV1) on the isokinetic dynamometer with three repetitions maximum voluntary isometric (MVC) for knee extension concomitant uptake of EMG for the VM muscle, VL and RF. Later, after application of NMES, they underwent an experimental protocol of isometric fatigue using 70% of MVIC, ending with the completion of a final assessment (AV2) in the same manner as the AV1. RESULTS: By analyzing the profile of the 60 subjects in three broad, VM showed a higher value of RMS behavior when the VL and RF (p = 0.03 and p = 0.02). With respect to Fmed the RF muscle (p = 0.001) showed a higher value for the VM. The VM muscle showed significant increases of Fmed (p = 0.05) after electrical stimulation at 70 Hz when compared the AV1 AV2 and RF showed significant decreases (p = 0.009) after stimulation at 30 Hz during the fatigue showed an increase RMS in the VM and VL, with a reduction in RF. For the variable Fmed was observed in three broad decline during fatigue. CONCLUSION: Our findings provide evidence that the muscles VM, VL and RF fiber typing are different besides indicating that the frequency of NMES tend to relate to the muscle stimulated. Finally suggests the surface EMG as a noninvasive method for characterizing muscle / OBJETIVO: Analisar os efeitos da eletroestimula??o sobre os par?metros eletromiogr?ficos e dinamom?tricos do m?sculo quadr?ceps. MATERIAIS E M?TODOS: Trata-se de um ensaio cl?nico controlado, randomizado e duplo cego. Sessenta volunt?rios saud?veis (23.6?4.2anos; 54.2?7.7Kg; 1,62?0,009cm) de ambos os sexos foram divididos aleatoriamente em tr?s grupos: grupo controle (GC), grupo experimental 1 (GE1) com aplica??o de corrente russa a 30 HZ e grupo experimental 2 (GE2) a 70 Hz. Os volunt?rios realizaram uma avalia??o inicial (AV1) no dinam?metro isocin?tico com 3 repeti??es isom?tricas volunt?rias m?ximas (CIVM), para extens?o do joelho concomitante a capta??o da EMG para os m?sculos vasto medial (VM), vasto lateral (VL) e reto femoral (RF). Posteriormente, ap?s aplica??o da eletroestimula??o neuromusuclar (EENM) foram submetidos a um protocolo experimental de fadiga isom?trica utilizando 70% da CIVM, finalizando com a realiza??o de uma avalia??o final (AV2), nos mesmos moldes da AV1. A an?lise dos dados se deu atrav?s da utiliza??o do programa estat?stico SPSS for Windows (Statistical Packege For the Social Sciense) 17.0 e foram utilizados Anova one way nas compara??es entre os grupos e teste t pareado nas compara??es dentro dos grupos. RESULTADOS: Ao analisar o perfil dos 3 vastos nos 60 sujeitos, o VM apresentou um maior valor de RMS quando comportamento ao VL e RF (p=0,03 e p=0,02). Com rela??o a Fmed, o m?sculo RF (p=0,001) apresentou maior valor comparado ao VM. O m?sculo VM apresentou aumentos significativos da Fmed (p=0,05) ap?s eletroestimula??o a 70 Hz quando a AV1 foi comparada a AV2 e o RF apresentou quedas significativas (p=0,009) ap?s estimula??o a 30 Hz. Durante a fadiga observou-se aumento do RMS no VM e VL, com redu??o no RF. Para a vari?vel Fmed observou-se queda nos tr?s vastos durante a fadiga. CONCLUS?O: Os achados deste estudo sugerem que os m?sculos VM, VL e RF possuem tipagens de fibras diferentes al?m de indicar que as frequ?ncias de EENM tendem a se relacionar com o m?sculo estimulado. Por fim sugere a EMG de superf?cie como um m?todo n?o invasivo para caracteriza??o muscular
