Quarenta e quatro volunt?rios do g?nero masculino (idade m?dia de 27,4?6,2 anos, IMC de 26,8? 3,8 Kg/m? e tempo de p?s operat?rio 17? 1,4 semanas) foram randomizados em 2 grupos: plataforma OFF (n=22, protocolo sobre a plataforma vibrat?ria desligada) e plataforma ON (n=22, protocolo sobre a plataforma vibrat?ria ligada, numa frequ?ncia de 50 Hz e amplitude de 4 mm). Todos os volunt?rios foram submetidos ? avalia??o do senso de posi??o articular do joelho (SPA), da avalia??o dinamom?trica do quadr?ceps femoral (isom?trica e conc?ntrica a 60?/s) e da atividade eletromiogr?fica dos m?sculos VL e VM, al?m da oscila??o do centro de press?o (baropodometria) em dois momentos distintos: antes e imediatamente ap?s o protocolo de interven??o. Os dados foram analisados por meio dosoftware SPSS 20.0, atribuindo-se n?vel de signific?ncia de 5%. A estat?stica descritiva ? apresentada pela m?dia (medida de tend?ncia central) e desvio padr?o (medida de dispers?o). Para verificar a homogeneidade dos grupos foi usada uma ANOVA one way, e para a compara??o intra e intergrupos, uma ANOVA mixed model. Resultados: foram observadas diferen?as entre as avalia??es pr? e p?s para as vari?veis velocidade latero lateral, pico de torque isom?trico e trabalho total, na compara??o intragrupos. Entretanto, n?o foi verificada diferen?a significativa na compara??o intergrupos ap?s a aplica??o do protocolo, sobre a plataforma vibrat?ria. Conclus?o: o uso da plataforma vibrat?ria n?o modifica de maneira imediata o desempenho do quadr?ceps femoral, a atividade eletromiogr?fica do VL e VM, bem como n?o interfere na oscila??o do centro de press?o de indiv?duos submetidos ? reconstru??o do LCA. === Objective: to investigate the immediate effect of the vibrating platform on the neuromuscular performance of the quadriceps femoris and on the postural oscillation of subjects submitted to Anterior Cruciate Ligament (ACL) reconstruction. Materials and methods: this study is a randomized and blind clinical trial. Forty-four male volunteers (average age of 27,4 ?6,2 IMC of 26,85? 3,8 Kg/m? and post surgery timeframe of 17? 1,4 weeks) were randomized into two groups: OFF platform (n=22, protocol of exercise over the vibrating platform off) and ON platform (n=22 protocol of exercise over the vibrating platform on, 50Hz frequency and 4mm of amplitude). All volunteers were submitted to assessment the isokinetic evaluation of the quadriceps femoris (isometric and isokinetic at 60?/s) and of the electromyography activity of the muscles Vasto Lateralis (VL) and Vasto Medialis (VM), besides the postural oscillation (baropodometry) in two distinct moments: before and immediately after the intervention protocol. The data was analyzed through the SPSS 20.0 software, with a 5% significance level. To verify the homogeneity of the groups it was used an ANOVA one way, and a ANOVA mixed model to compare the intra and inter groups. Results: it was observed differences between the pre and the post, to latero lateral velocity, isometric torque peak and total work in comparison with intragroup. However, it wasn?t verified any difference in comparing the intergroup in the preevaluation and in the post-evaluation protocol over the vibrating platform. Conclusion: the use of the vibrating platform doesn?t change as an immediate manner the isokinetic performance of the quadriceps femoris, the electromyography activity of the VL and the VM, also doesn?t interfere with the postural oscillation of individuals that were submitted to the ACL reconstruction.
