Abstract:
Objective:The purpose of this study was to investigate the effects of neuromuscular electrical stimulation (NMES) in different frequencies on the quadriceps femoris. A randomized, controlled, blind cross-sectional study. Methods:Thirty subjects (12 men and 18 women), with an average age of 24.67 years, weight of 65.62 kg and height of 1.69 m were evaluated. Three random test conditions were applied: maximum voluntary isometric contraction (MVIC), maximum voluntary isometric contraction with medium frequency current (MVIC-MF) and maximum voluntary isometric contraction with low frequency current (MVIC-LF). Four MVICs were applied in each situation. The time between different isometric contraction types was 90 seconds while the time between the same conditions of contraction was 10 seconds. Results:Two-way ANOVA test showed that MVIC-MF had higher values for peak torque than MVIC-LF (p=0.02). Significant statistical results were found when comparing MVIC-MF and MVIC (p=0.03), but not for MVIC and MVIC-LF (p=0.52). Conclusion:Maximum voluntary isometric contraction associated with medium-frequency electrical stimulation was more effective than other NMES conditions. Level of Evidence II, Therapeutic Studies - Investigation of treatment results. Objetivo:A finalidade deste estudo foi investigar os efeitos da estimulação elétrica neuromuscular (EENM) em diferentes frequências sobre o músculo quadríceps femoral. Estudo randomizado, transversal, controlado e cego. Métodos:Foram avaliados trinta indivíduos de ambos os sexos (12 homens e 18 mulheres) com média de idade de 24,67 anos, peso 65,62 kg e altura 1,69 m. Os indivíduos foram submetidos a três condições de testes randomizados: contração voluntária isométrica máxima (CVIM), contração voluntária isométrica máxima associada à corrente de média frequência (CVIMMF) e contração voluntária isométrica máxima associada à baixa frequência (CVIMBF), sendo realizadas quatro repetições de CVIM em cada situação. O tempo entre as diferentes condições de contrações isométricas foi de 90 segundos e o tempo entre as contrações isométricas das mesmas condições foi de 10 segundos. Resultados:O teste ANOVA mostrou que a CVIMMF obteve valores de pico de torque maiores do que a CVIMBF (p = 0,02), com diferença significativa. Foram encontrados resultados com significância estatística ao comparar CVIMMF e CVIM (p = 0,03), mas não entre CVIM e CVIMBF (p = 0,52). Conclusões:A contração voluntária isométrica máxima associada a EENM de média frequência foi mais efetiva do que as outras situações de EENM. Nível de evidência II, Estudos Terapêuticos – Investigação dos resultados do tratamento.
