ABSTRACT

Summary Introduction: Digital palpation and manometry are methods that can provide information regarding maximum voluntary contraction (MVC) and endurance of the pelvic floor muscles (PFM), and a strong correlation between these variables can be expected. Objective: To investigate the correlation between MVC and endurance, measured by digital palpation and manometry. Method: Forty-two women, with mean age of 58.1 years (±10.2), and predominant symptoms of stress urinary incontinence (SUI), were included. Examination was firstly conducted by digital palpation and subsequently using a Peritron manometer. MVC was measured using a 0-5 score, based on the Oxford Grading Scale. Endurance was assessed based on the PERFECT scheme. Results: We found a significant positive correlation between the MVC measured by digital palpation and the peak manometric pressure (r=0.579, p<0.001), and between the measurements of the endurance by Peritron manometer and the PERFECT assessment scheme (r=0.559, P<0.001). Conclusion: Our results revealed a positive and significant correlation between the capacity and maintenance of PFM contraction using digital and manometer evaluations in women with predominant symptoms of SUI.


Resumo Introdução: a palpação digital e a manometria são métodos capazes de fornecer informações sobre contração voluntária máxima (CVM) e endurance da musculatura do assoalho pélvico (MAP), e pode-se esperar uma forte correlação entre essas variáveis. Objetivo: investigar a correlação entre CVM e endurance, avaliados por palpação digital e manometria. Método: incluíram-se 42 mulheres, com idade média de 58,1 anos (±10,2) e sintomas predominantes de incontinência urinária de esforço (IUE). Realizou-se primeiramente o exame digital, seguido pela manometria (Peritron®). Mensuraram-se a CVM de acordo com a escala de Oxford (0-5 pontos) e o endurance pelo esquema PERFECT. Resultados: encontrou-se correlação positiva entre CVM mensurada por palpação digital e pressão manométrica de pico (r=0,579; p<0,001), e entre as medições do endurance avaliado pelo Peritron e o esquema PERFECT (r=0,559; p<0,001). Conclusão: os resultados revelaram correlação positiva e significativa entre a capacidade e a manutenção de contração dos MAP por meio das avaliações digital e manométrica em mulheres com IUE.
