Correlação entre a manometria e dinamometria dos músculos do assoalho pélvico em mulheres no período da menacme e climatério

Abstract

Introduction: Pelvic floor dysfunctions are a global health problem that encompasses several disorders. The combination of risk factors, anatomical alterations, and weakening of the pelvic floor components can lead to the appearance of pathological symptoms associated with changes in its function. In this sense, the evaluation of the pelvic floor muscles (PFM) is of utmost importance, with sensitive and accurate resources, in order to assess muscle function, mainly before and after a PFM training program. Objective: to evaluate the correlation between PFM function and strength through vaginal manometry and dynamometry. Methodology: Cross-sectional observational study, carried out from May/2023 to July/2024, composed of 91 women in the reproductive and non-reproductive period, recruited at the Januário Cicco Maternity School (MEJC) of the Federal University of Rio Grande do Norte (UFRN), Natal/RN/Brazil. Data collection was performed by applying a questionnaire on sociodemographic and clinical data, followed by functional assessment of the PFM using palpation, manometry and vaginal dynamometry. Descriptive statistics were used to characterize the data. Pearson's correlation test was used to verify the correlations between vaginal manometry and vaginal dynamometry. Receiver Operating Characteristic (ROC) analysis was used to establish the sensitivity and specificity of the PFM functional tests. Results: The analysis of the correlation between the manometry and dynamometry results was positive, moderate and significant (r = 0.4; p = 0.01). The ROC curve of the dynamometry showed an area under the curve of 66%, which was considered statistically significant (95% CI: 0.53- 0.78; p = 0.024). The established cut-off point was 0.5141, with a sensitivity of 70.6% and a specificity of 52.6%. Conclusion: The correlation between manometry and vaginal dynamometry was moderate, demonstrating vaginal dynamometry as a powerful assessment tool.
