[Purpose] The purpose of this study was to examine the reliability of ultrasound measurements by analyzing the relative reliability and absolute reliability when measuring soft tissue thickness around the shoulder joint. [Subjects and Methods] Eleven healthy young adults (22 shoulders) participated in this study. Thickness of the supraspinatus tendon, subacromial bursa, and biceps tendon was measured on both shoulders. This protocol was performed twice in the same day. The relative reliability of ultrasound measurement was evaluated using the intraclass correlation coefficient for determining the degree of consistency and agreement between two measures. The absolute reliability of the ultrasound measurement was evaluated using the standard error of measurement, minimum detectable change, and Bland-Altman analysis. [Results] Ultrasound measurements exhibited high relative reliability: intraclass correlation coefficients for the supraspinatus tendon, subacromial bursa, and biceps tendon thickness were demonstrated to be 0.91, 0.82, and 0.90, respectively. Bland-Altman analyses revealed no significant systematic bias between the repeated measurements for the supraspinatus tendon, subacromial bursa, and biceps tendon thickness. [Conclusion] These findings suggest that ultrasound measurement for the supraspinatus tendon, subacromial bursa, and biceps tendon thickness exhibited good relative reliability and no systematic errors were detected regarding their absolute reliability.
[目的] 本研究的目的是通过分析测量肩关节周围软组织厚度时的相对可靠性和绝对可靠性，来检验超声测量的可靠性。[对象与方法] 11名健康年轻成年人（22个肩部）参与了本研究。对双侧肩部的冈上肌腱、肩峰下滑囊和肱二头肌肌腱厚度进行测量。该方案在同一天进行两次。使用组内相关系数评估超声测量的相对可靠性，以确定两次测量之间的一致性程度和一致性。使用测量标准误差、最小可检测变化和Bland-Altman分析评估超声测量的绝对可靠性。[结果] 超声测量显示出较高的相对可靠性：冈上肌腱、肩峰下滑囊和肱二头肌肌腱厚度的组内相关系数分别为0.91、0.82和0.90。Bland-Altman分析显示，冈上肌腱、肩峰下滑囊和肱二头肌肌腱厚度的重复测量之间无显著系统偏差。[结论] 这些结果表明，超声测量冈上肌腱、肩峰下滑囊和肱二头肌肌腱厚度具有良好的相对可靠性，且在绝对可靠性方面未检测到系统误差。
