简要总结
We will evaluate the inter-and intra-rater reliability of pelvic floor morphometry obtained from transperineal ultrasound images collected at rest and during standardized weight lifting tasks.
详细描述
The aim is to evaluate the inter-rater and intra-rater reliability of pelvic floor morphometry at rest and during dynamic, externally loaded barbell resistance training tasks using 2-dimensional (2D) transperineal ultrasound (TPUS) imaging in individuals with female pelvic anatomy. Establishing measurement reliability under these conditions is a necessary methodological prerequisite for future research in which we plan to investigate pelvic floor behaviour during resistance training and its potential relationship to exercise-induced urinary incontinence.
After a standard bladder filling protocol, TPUS imaging will be performed by two trained assessors using 2D ultrasound. Images and cine loops will be acquired under four standardized conditions: supine; standing; three loaded barbell back squats at 40%, 60%, and 80% of the participant's one-repetition maximum (1RM); and three loaded barbell deadlifts at 40%, 60%, and 80% of 1RM. Images and cine loops will be processed offline to measure levator plate length, levator plate angle, bladder neck height and anorectal junction height. The inter and intra-rater reliability of image acquisition and analysis will be determined for each measure under each condition.

结局指标
主要结局
Bladder Neck Height
时间窗: Day 1
Bladder neck height will be measured from 2D ultrasound images as the length of a line drawn perpendicularly from the long axis of the pubic symphysis to the bladder neck.
Levator Plate Length
时间窗: Day 1
The levator plate length will be measured from the ultrasound images as the linear distance between the posterior margin of the pubic sympysis and the anterior margin of the anorectal junction.
Ano-rectal Junction Height
时间窗: Day 1
Ano-rectal junction height will be measured from the ultrasound images as the length of a line drawn perpendicularly from the long axis of the pubic symphysis to the anterior margin of the anorectal junction.
Levator Plate Angle
时间窗: Day 1
Levator plate angle will be assessed using ultrasound imaging.The images will be recorded under the standardized conditions.
Bladder Neck Funnelling
时间窗: single visit
Bladder neck funnelling will be assessed dichotomously as present or absent based on the visualization of an opening of the proximal urethra.
