Introdução: A eletromiografia tem-se demonstrado um método eficaz e confiável na avaliação da função muscular do pavimento pélvico em mulheres nulíparas saudáveis, contudo a sua confiabilidade em mulheres com lacerações após o parto continua por esclarecer. Objetivo: Avaliar a confiabilidade intra-observador do Biofeedback Eletromiográfico (BFB EMG) (Physioplux Clinical) em mulheres nulíparas e em primíparas com lacerações de grau II. Metodologia: Foi realizado um teste-reteste do BFB EMG em 12 mulheres (8 nulíparas e 4 primíparas) para avaliar a confiabilidade deste instrumento durante a medição do repouso e da contração voluntária máxima (CVM) do pavimento pélvico. Posteriormente, foram calculados os índices de confiabilidade: Intraclass Correlation Coefficient (ICC), standard error of measurement (SEM) e minimal detectable change (MDC). Resultados: O BFB EMG demonstrou muito boa confiabilidade intra-observador em mulheres nulíparas para a CVM(pico) do pavimento pélvico (ICC:0,93) mas pobre confiabilidade na avaliação das primíparas com lacerações de grau II (ICC: 0,25). Conclusão: Os resultados do ICC obtidos sugerem que a utilização do BFB EMG não é recomendada na avaliação da função muscular do pavimento pélvico em primíparas com lacerações grau II. Apesar do valor de ICC nas nulíparas demonstrar boa confiabilidade do BFB EMG, uma vez que os valores de SEM e MDC encontrados foram elevados a confiabilidade deste instrumento poderá estar comprometida. Estes resultados estão limitados pelo tamanho da amostra, pelo que não é possível generalizar as conclusões obtidas. Deste modo, são necessários mais estudos no futuro sobre a confiabilidade deste instrumento de medida nesta população.
ABSTRACT - Introduction: Electromyography has been shown to be an effective and reliable method for evaluating pelvic floor muscle function in healthy nulliparous women, however, its reliability in women with lacerations after childbirth remains unclear. Objectives: To evaluate the inter-rater reliability of the Electromyographic Biofeedback (EMG BFB) (Physioplux Clinical) in nulliparous women and in primiparous women with grade II lacerations. Methods: An electromyographic biofeedback test-retest was performed on 12 women (8 nulliparous and 4 primiparous) to assess the reliability of this instrument during the measurement of rest and maximal voluntary contraction (MVC) of the pelvic floor. Subsequently, the reliability indexes were tested: Intraclass Correlation Coefficient (ICC), standard error of measurement (SEM), and minimal detectable change (MDC). Results: The EMG BFB demonstrated very good inter-rater reliability in nulliparous women for MVC (peak) of the pelvic floor (ICC: 0.932) but poor reliability in the evaluation of primiparous women with grade II lacerations (ICC: 0.251). Conclusion: The results of the ICC obtained suggest that the use of EMG BFB is not recommended in the evaluation of the muscular function of primiparous women with grade II lacerations. Despite the ICC value in the nulliparous women demonstrating very good reliability of the BFB EMG, since the SEM and MDC values found were high, the reliability of this instrument may be compromised. These results are limited by the sample size, so it is not possible to generalize the conclusions obtained. Further studies are needed in the future on the reliability of this measurement instrument in this population.
