Abstract
INTRODUCTION AND HYPOTHESIS: The International Continence Society recommends vaginal palpation as a method for assessing pelvic floor muscle (PFM) function. Our aim was to analyze the agreement between preferences of examiner and participants according to unidigital and bidigital vaginal palpation during PFM assessment. The second aim was to investigate qualitatively women's perception of vaginal palpation. METHODS: Maximal voluntary contractions (MVCs) were requested during both types of vaginal palpation and were classified by the Modified Oxford Scale (MOS). Examiner and participants answered if they had preferences regarding vaginal palpation. Women answered qualitatively what they felt during the assessment. Cohen's linear kappa (κ) evaluated the agreement after allocation of the women with a weaker and stronger MVC and qualitative analysis was performed by transcription considering age range (18-35; 36-59; ≥60 years). RESULTS: Agreement was almost zero for women with weaker and stronger MVC at unidigital (κ = 0.06 and κ = -0.12) and bidigital vaginal palpation (κ = 0.008 and κ = 0.005). Participants associated bidigital palpation with more perception and an easier way of contracting the PFMs. Women between 36 and 59 years associated unidigital palpation with a harder but comfortable way of contracting the PFMs. Subjects aged ≥60 years associated bidigital palpation with an uncomfortable, harder way of contracting PFM, with less space into the vagina. CONCLUSIONS: Agreement between preferences was almost zero neither between women with a weaker and stronger PFM contraction, nor between the types of vaginal palpation. Bidigital palpation increased women's perception, made the contraction easier, and was associated with less space in the vaginal canal and less comfort.
