目的：本研究的目的是确定治疗师内的可靠性，指肌肉测试和阴道测压的最大随意收缩力量和耐力。此外，我们评估了不同工具和不同测试位置的可靠性如何变化。方法：研究对象为20名女性物理治疗师。改良的牛津量表用于指肌测试，Peritron（TM）会阴测量仪用于阴道静息压和阴道挤压压评估。进行了强度和耐久性试验。最大自主收缩分数中的最高者用于力量分析，疲劳指数值由耐力重复计算。采用屈膝卧位、仰卧位、坐位和站立位。会话之间的可靠性的时间间隔为2-6周。结果如下：手指肌肉测试的会话间可靠性的Kappa值分别为0.69，0.69，0.86和0.79的四个测试位置，分别。对于最大自主收缩，四个位置的挤压压力读数的类内相关系数（ICC）值分别为0.95、0.91、0.96和0.92，对于耐久性测试，ICC值分别为0.05、0.42、0.13和0.35。静息压的ICC值分别为0.74、0.77、0.47和0.29。结论：指肌测试的可靠性在坐位上非常好，在其他三个位置上也很好。对于最大自主收缩，阴道静息压在所有四个位置上都表现出非常好的可靠性，但是对于耐力测试是不可靠的。阴道静息压是不可靠的直立位置。两种测量工具在某些位置都是可靠的，测压法显示出更高的可靠性系数。
Aims: The aims of this study were to determine the intra-therapist reliability for digital muscle testing and vaginal manometry on maximum voluntary contraction strength and endurance. In addition, we assessed how reliability varied with different tools and different testing positions. Methods: Subjects included 20 female physiotherapists. The modified Oxford scale was used for the digital muscle testing, and the Peritron (TM) perineometer was used for the vaginal resting pressure and vaginal squeeze pressure assessments. Strength and endurance testing were performed. The highest of the maximum voluntary contraction scores was used in strength analysis, and a fatigue index value was calculated from the endurance repetitions. Bent-knee lying, supine, sitting, and standing positions were used. The time interval for between-session reliability was 2-6 weeks. Results: Kappa values for the between-session reliability of digital muscle testing were 0.69, 0.69, 0.86, and 0.79 for the four test positions, respectively. Intra-class correlation coefficient (ICC) values for squeeze pressure readings for the four positions were 0.95, 0.91, 0.96, and 0.92 for maximum voluntary contraction, and 0.05, 0.42, 0.13, and 0.35 for endurance testing. ICC values for resting pressure were 0.74, 0.77, 0.47, and 0.29. Conclusions: Reliability of digital muscle testing was very good in sitting and good in the other three positions. vaginal resting pressure demonstrated very good reliability in all four positions for maximum voluntary contraction, but was unreliable for endurance testing. Vaginal resting pressure was not reliable in upright positions. Both measurement tools are reliable in certain positions, with manometry demonstrating higher reliability coefficients.
