BACKGROUND: Vaginal manometry is regarded as an objective method to assess pelvic floor muscles (PFM) function and can measure several variables during contraction. OBJECTIVE: To determine which variables could differentiate women with/without a weak/strong PFM contraction and determine their cut-off points. METHODS: This is a diagnostic accuracy study performed on 156 women with a mean age of 40.4 (SD, 15.9) years. The reference test was vaginal palpation and the index test was vaginal manometry (Peritron™ manometer). Variables were pressure at rest, pressure achieved with maximal voluntary contraction (MVC), MVC average, duration, gradient, and area under the curve (AUCm). The Receiver Operating Curve (AUC/ROC) and logistic regression were used to analyze the data and obtain cut-off points. RESULTS: Excellent ability to discriminate women with a weak/strong PFM contraction was found for MVC average (cut-off: 28.93 cmH2O), MVC (cut-off: 38.61 cmH2O), and the AUCm (cut-off: 1011.93 cm²*s). The gradient variable had good discrimination ability (AUC/ROC=0.81; cut-off: 28.68 cmH2O/s). The MVC average assessed by manometry, menopausal status, and the presence of stress urinary incontinence (SUI) were associated with a weak/strong PFM contraction in the multivariate analysis; however, the most parsimonious model to discriminate weak/strong PFM contraction included only the MVC average (AUC/ROC = 0.95; sensitivity: 0.87; specificity: 0.91). CONCLUSION: These results suggest which manometry variables are appropriate to assess and classify PFM function in females. These could be used to help physical therapists to make clinic decisions about the management of female PFM.
