AIMS To investigate if pelvic floor muscle (PFM) thickness and area of levator hiatus (LH) are associated with manometry measured PFM function in 109 women with pelvic organ prolapse (POP) stages I-III. METHODS In this cross-sectional study pubovisceral muscle thickness and LH area were assessed with three-dimensional transperineal ultrasound at rest and(More)
The aims of the present study were to evaluate test-retest intra-observer repeatability of ultrasound measurement of the morphology and function of the pelvic floor muscles (PFMs). Seventeen subjects were tested twice. Two-, three- and four- dimensional ultrasound recorded cough, huff, muscle morphology and PFM contraction, respectively. Analyses were(More)
AIMS The aim of the present study was to evaluate test-retest measurements of functional aspects of pelvic floor muscle (PFM) contraction using four dimensional (4D) ultrasound. METHODS Seventeen females preformed three maximal PFM contractions in standing, recorded by 4D real time ultrasound, on two separate occasions. RESULTS Very good and good(More)
A new theory claims that the pelvic floor muscles (PFM) can be trained via the transversus abdominis (TrA). The aim of the present study was to compare the effect of instruction of PFM and TrA contraction on constriction of the levator hiatus, using 4D perineal ultrasonography. Thirteen women with pelvic organ prolapse participated in the study. Perineal(More)
