| Abstract: | [Purpose] The purpose of this study was to investigate the reliability of measuring theamount of pelvic floor elevation during pelvic and abdominal muscle contraction with adiagnostic ultrasonic imaging device. [Subjects] The study group comprised 11 healthywomen without urinary incontinence or previous birth experience. [Methods] We measured thedisplacement elevation of the bladder base during contraction of the abdominal and pelvicfloor muscles was measured using a diagnostic ultrasonic imaging device. The exercise wasa four-part operation undertaken with the subjects in the lateral position. Thereliability analysis included use of the interclass correlation coefficient (ICC) was usedto assess the reliability. [Results] ICC (1.1) values for the pelvic floor elevationmeasurement with a diagnostic ultrasonic imaging device were 0.98 [contraction of thetransversus abdominis (TrA) muscle], 0.99 [contraction of pelvic floor muscles (PFMs)],0.98 (co-contraction of the TrA and PFMs), and 0.98 (resistance of the TrA and PFMs). Thisstudy proved the reliability of the method because the coefficient of reliability was 0.97or more for all of the measurements, even for those during exercise. [Conclusion] Thediagnostic ultrasonic imaging device measures pelvic floor elevation with highreliability.Key words: Bladder base, Pelvic floor muscles (PFMs), Stress urinary incontinence |
