This study aims to evaluate the intra- and inter-rater reliability coefficients of the supraspinatus tendon thickness, acromiohumeral distance, and occupation ratio in patients with shoulder impingement syndrome.
The study included 83 patients (21 males, 62 females; mean age 51.6±11.0 years; range, 26 to 70 years) with shoulder impingement syndrome. The supraspinatus tendon thickness, acromiohumeral distance, and occupation ratio values were obtained one week apart by two observers. The intraclass correlation coefficient (ICC), minimum detectable change, and standard error of measurement were calculated.
The first observer had excellent intra-rater reliability in all measurements (ICC >0.90) with minimum detectable change of 0.740-0.047 mm and standard error of measurement of 0.017-0.26 mm. The second observer had excellent intra-rater reliability in supraspinatus tendon thickness and acromiohumeral distance measurements (ICC >0.90) with minimum detectable change of 0.498-0.770 mm and standard error of measurement of 0.18-0.28 mm and good intra-rater reliability in the occupation ratio measurement (ICC; 0.75-0.90) with minimum detectable change of 0.060 mm and standard error of measurement of 0.022 mm. Inter-rater reliability coefficients were 0.916 (95% confidence interval [CI]; 0.873-0.945) for supraspinatus tendon thickness, 0.943 (95% CI; 0.914-0.963) for acromiohumeral distance with minimum detectable change of 0.673 mm and standard error of measurement of 0.243 mm and 0.790 (%95 CI; 0.693-0.853) for occupation ratio with minimum detectable change of 0.077 mm and standard error of measurement of 0.028 mm.
These findings suggest that ultrasonographic measurements of the supraspinatus tendon thickness, acromiohumeral distance and occupation ratio can be reliable and consistent for clinical evaluation of patients with shoulder impingement syndrome in terms of supporting diagnosis and monitoring the treatment effect.
本研究旨在评估肩峰撞击综合征患者冈上肌腱厚度、肩峰下间隙及占位比的组内和组间可靠性系数。
本研究纳入83例肩峰撞击综合征患者（男性21例，女性62例；平均年龄51.6±11.0岁；范围26至70岁）。由两名观察者在相隔一周的时间获取冈上肌腱厚度、肩峰下间隙及占位比数值。计算组内相关系数（ICC）、最小可检测变化及测量标准误差。
第一位观察者在所有测量中均具有出色的组内可靠性（ICC>0.90），最小可检测变化为0.740 - 0.047mm，测量标准误差为0.017 - 0.26mm。第二位观察者在冈上肌腱厚度和肩峰下间隙测量中具有出色的组内可靠性（ICC>0.90），最小可检测变化为0.498 - 0.770mm，测量标准误差为0.18 - 0.28mm，在占位比测量中具有良好的组内可靠性（ICC；0.75 - 0.90），最小可检测变化为0.060mm，测量标准误差为0.022mm。组间可靠性系数方面，冈上肌腱厚度为0.916（95%置信区间[CI]；0.873 - 0.945），肩峰下间隙为0.943（95%CI；0.914 - 0.963），最小可检测变化为0.673mm，测量标准误差为0.243mm，占位比为0.790（%95CI；0.693 - 0.853），最小可检测变化为0.077mm，测量标准误差为0.028mm。
这些结果表明，超声测量冈上肌腱厚度、肩峰下间隙及占位比在支持肩峰撞击综合征患者的诊断及监测治疗效果方面，对于临床评估而言可以是可靠且一致的。
