The effect of different exercises on the position of pelvic organs in women has not been sufficiently assessed. The objective was to analyze the validity and reliability of a new two-dimensional ultrasound algorithm to measure offline the displacement of the bladder base during abdominal exercises. This algorithm could be a useful method to future studies in determine the most appropriate exercises in sports and in rehabilitative program for the pelvic floor in women. All subjects were tested by transverse transabdominal ultrasound. The measurements were conducted offline using a customized code written in MATLAB (Ecolab) for image-processing, and manually on the ultrasound monitor using electronic calipers. The agreement was assessed with a paired -test, Pearson's linear correlation coefficient (), the Lin's concordance correlation coefficient (CCC), the intraclass correlation coefficient ICC (A,2) and a Bland-Altman plot. The reliability was confirmed by the interdays intra-rater ICC coefficient. The results were that Ecolab and ultrasound transducer measures did not differ statistically ( = 0.246). Furthermore, both methods showed a very strong relationship, and the Ecolab demonstrated to be a valid and reliable method. We concluded that Ecolab seemed to be a valid and reliable tool to assess the effect of abdominal contractions in the female pelvic floor.
不同运动对女性盆腔器官位置的影响尚未得到充分评估。目的是分析一种新的二维超声算法在离线测量腹部运动期间膀胱底部位移的有效性和可靠性。该算法可能是未来研究确定女性盆底运动和康复计划中最合适运动的有用方法。所有受试者均接受经腹横向超声检查。测量是离线进行的，使用用MATLAB（Ecolab）编写的定制代码进行图像处理，并在超声监视器上使用电子卡尺手动测量。通过配对检验、Pearson线性相关系数（）、Lin一致性相关系数（CCC）、组内相关系数ICC（A，2）和Bland-Altman图评估一致性。通过日间评分者内ICC系数确认可靠性。结果显示，Ecolab测量值与超声换能器测量值在统计学上无差异（=0.246）。此外，两种方法均显示出很强的相关性，且Ecolab被证明是一种有效且可靠的方法。我们得出结论，Ecolab似乎是评估腹部收缩对女性盆底影响的有效且可靠的工具。
