摘要：

      摘要 目标：测试康复超声成像技术测量健康青年腹部肌肉厚度及其信度。 方法：健康青年30例，使用康复超声成像技术测量腹部腹外斜肌、腹内斜肌和腹横肌在放松仰卧位的厚度。由初学测试者A和有经验测试者B分别进行测量，其中初学测试者A在3d后重复测试一次。计算组内相关系数（ICC）和最小检测变化值（MDC）。 结果：初学测试者A的重复性测量信度均为优秀（ICC＞0.90）；最小检测变化值在0.03—0.09cm之间，显示测量误差较小；不同施测者间信度分析均为好（0.75＜ICC＜0.90）；左右两侧腹外斜肌、腹内斜肌与腹横肌肌肉厚度皆无显著差异（P＞0.05）。 结论：康复超声技术可以准确、有效测量腹外斜肌、腹内斜肌和腹横肌的厚度，健康青年左右两侧的肌群厚度对称。

Abstract:

      Abstract Objective: To investigate the reliability of rehabilitative ultrasound imaging for measuring the thickness of external oblique, internal oblique and transversus abdominis muscles in healthy youth. Method: Thirty healthy youth were recruited to measure the abdominal muscles thickness with rehabilitative ultrasound imaging by two therapists, one of the raters re-tested 3d later. The interclass correlation coefficient(ICC) and minimum detectable change(MDC) were calculated. Result: The intra- and inter-rater reliabilities of muscle thickness measurement were excellent (ICC＞0.90); the MDC ranged from 0.03cm to 0.09cm; different inter-rater reliabilities were well (0.75＜ICC＜0.90); There was no significant difference between left and right sides for all abdominal muscles (P＞0.05). Conclusion: Rehabilitation ultrasound technology can be used to measure external oblique, oblique and transversus abdominis muscles thickness in healthy youth accurately and effectively, the abdominal muscles thicknesses of both left and right sides of healthy youth are symmetrical.
