“…However, for G2 and G3, bidigital palpation showed higher intra‐rater reliability. Although similar results have been published in the literature, methodological differences related to sample size, methodological designs, and statistical methods among the studies did not enable direct comparison of their results.…”

“…This may be one reason for the variable reliability found in previous reproducible studies. However, vaginal palpation may be a difficult method to use to quantify PFM function due to anatomical variability and experience‐evaluator dependence . In particular, it is not yet known whether the introduction of one or two fingers into the vaginal canal may influence the measurement of the MVC of the PFM.…”

Aims: Evaluate the intra-and inter-rater reliability of maximal voluntary contraction (MVC) of pelvic floor muscle (PFM) assessment by unidigital and bidigital vaginal palpation. As a secondary aim, evaluate the construct validity of vaginal palpation and a manometer.Methods: A total of 120 women were recruited and allocated into three groups according to age (group 1 [G1]: 18-35; G2: 36-59; G3: ≥60 years). Examiner A conducted an interview and examiners B and C performed evaluations of PFM function using both unidigital and bidigital vaginal palpation. Seven to 10 days later, examiner B repeated both types of vaginal palpation and measured the MVC pressure with a Peritron. Reliability was analyzed using Cohenʼs linear weighted Kappa (κ w ). The construct validity was calculated using the Spearmanʼs correlation (r s ).Results: Intra-rater reliability of unidigital and bidigital palpation was κ w = 0.75 and κ w = 0.58 in G1, κ w = 0.59 and κ w = 0.73 in G2, and κ w = 0.79 and κ w = 0.86 in G3, respectively. Inter-rater reliability of unidigital and bidigital palpation was κ w = 0.52 and κ w = 0.48 in G1, κ w = 0.47 and κ w = 0.52 in G2, and κ w = 0.50 and κ w = 0.64 in G3, respectively. Spearmanʼs correlation coefficients were significant at r s = 0.79 and r s = 0.80 for unidigital and bidigital vaginal palpation, respectively.Conclusions: Unidigital or bidigital vaginal palpation were indicated to evaluate G1 and G2 but bidigital palpation was more reliable in G3 when two examiners performed the evaluation. For the assessment conducted by one examiner, unidigital palpation was more reliable in G1 while bidigital palpation was more reliable in G2 and G3. Both unidigital and bidigital palpation have high measures of validity.

PFM function assessed by bidigital palpation in postmenopausal women was not sufficiently sensitive to differentiate between women with vs. women without PFM dysfunction and was not related with specific quality of life in women with urinary incontinence and pelvic organ prolapse, respectively. These data should be used to reinforce the widespread recommendation that PFM training is essencial in PFD treatment.

“…At around the age of 40 years, there is a decline in hormone levels, primarily estrogens, which tends to decrease in tropism and strength in these muscles. The reduced ability to generate PFM strength will hinder urethral closure and the emergence and/or aggravation of LUTS5,6,7 ) .…”

[Purpose] To assess lower urinary tract symptoms in different stages of menopause and the quality of life of females with incontinence. [Subjects and Methods] The sample consisted of 302 females, aged between 40 and 56 years, divided into three groups: PRE (n= 81), PERI (n= 108) and POST (n= 113). This was a cross-sectional, analytical, observational study. Data were collected by assessment chart and conducting the International Consultation on Incontinence Questionnaire-Short Form. [Results] Most of the women had less than 10 years of schooling and were married. In PERI and POST menopause, the most frequent lower urinary tract symptoms were urinary urgency and stress incontinence. The PRE group did not exhibit nocturia, urge incontinence or urinary urgency, and had the lowest symptoms frequency. In the three stages, stress incontinence was the most prevalent symptom. Of the three menopause stages, PERI had a greater impact on urinary incontinence according to the International Consultation on Incontinence Questionnaire. [Conclusion] The presence of lower urinary tract symptoms can vary across the different stages of menopause and the urinary incontinence was the most frequent complaint. Moreover, it was observed that quality of life was more affected in the perimenopause stage.
