Quantitative tools to assess pelvic floor muscle function - systematic review.

Abstract

Objectives: Urinary incontinence is pelvic floor muscles dysfunction, most often caused by a weakening of their strength. There are no guidelines on how to evaluate pelvic floor muscle function. Palpation is the most popular method of assessing pelvic floor muscle function, but it is subjective. The aim of the study was to review the objective methods used in the assessment of pelvic floor muscle function in women with urinary incontinence.

Material and methods: A systematic literature review of the PubMed database was performed using the following keywords: ["Pelvic Floor" (mh)] AND [("Pelvic Floor Disorders" (mh)] OR ["Urinary Incontinence" (mh)]. The search was limited to English-language works published from 2011 to 2021. The inclusion criteria were interventional studies in which the pelvic floor muscle function of women with urinary incontinence was assessed using quantitative tools. Methods that cannot be used in the clinic were excluded from the analysis.

Results: Fifty-two articles were included in the analysis and five methods assessing the function of pelvic floor muscle were distinguished: manometry, electromyography (EMG), ultrasonography (USG), dynamometry, accelerometry.

Conclusions: Manometry, EMG and USG are the most common objective methods of assessing pelvic floor muscle function. When taking measurements, it is important to choose the right position of the patient. The use of objective tools to assess the function of the pelvic floor muscle and obtaining quantitative and/or qualitative data allows us to precisely diagnose and monitor the treatment and rehabilitation progress.
