本研究的目的是评估在两种常用的躯干稳定性练习中测量的腹肌剪切模量的会话内和评分者间的可靠性。30名健康志愿者进行了一系列的腹部中空和腹部支撑任务。超声剪切成像用于测量四个前躯干肌肉的剪切模量（被认为是肌肉张力的指标）：腹外肌、腹内肌、腹横肌和腹直肌。由于测量伪影，分别有36.7%和26.7%的参与者的腹内肌和腹横肌数据未进行分析。这些参与者表现出比其他人更厚的表面脂肪层。对于其余的参与者，观察到中等至高的组内系数（0.45-0.97）和低至中等的测量值标准误（0.38-3.53 kPa），具有良好的会话内和评估者间可靠性。可靠性值始终大于浅表比深层肌肉。（电子邮件：francois. univ-nantes.fr）（C）2016年世界医学和生物学超声联合会。
The aim of this study was to assess the intra-session and inter-rater reliability of shear modulus measured in abdominal muscles during two commonly used trunk stability exercises. Thirty healthy volunteers performed a series of abdominal hollow and abdominal brace tasks. Supersonic shear imaging was used to measure the shear modulus (considered an index of muscle tension) of the four anterior trunk muscles: obliquus externus abdominis, obliquus internus abdominis, transversus abdominis and rectus abdominis. Because of measurement artifacts, internus abdominis and transversus abdominis data were not analyzed for 36.7% and 26.7% of the participants, respectively. These participants exhibited thicker superficial fat layers than the others. For the remaining participants, fair to excellent intra-session and inter-rater reliability was observed with moderate to high intraclass coefficients (0.45-0.97) and low to moderate standard error of measurement values (0.38-3.53 kPa). Reliability values were consistently greater for superficial than for deeper muscles. (E-mail: francois.hug@univ-nantes.fr) (C) 2016 World Federation for Ultrasound in Medicine & Biology.
