BACKGROUND
The Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) has been proposed as an option to assess upper limb function and stability; however, there are few studies that support the use of this test in adolescents.
PURPOSE
The purpose of the present study was to investigate the intersession reliability and agreement of three CKCUEST scores in adolescents and establish clinimetric values for this test.
STUDY DESIGN
Test-retest reliability.
METHODS
Twenty-five healthy adolescents of both sexes were evaluated. The subjects performed two CKCUEST with an interval of one week between the tests. An intraclass correlation coefficient (ICC) two-way mixed model with a 95% interval of confidence was utilized to determine intersession reliability. A Bland-Altman graph was plotted to analyze the agreement between assessments. The presence of systematic error was evaluated by a one-sample t test. The difference between the evaluation and reevaluation was observed using a paired-sample t test. The level of significance was set at 0.05. Standard error of measurements and minimum detectable changes were calculated.
RESULTS
The intersession reliability of the average touches score, normalized score, and power score were 0.68, 0.68 and 0.87, the standard error of measurement were 2.17, 1.35 and 6.49, and the minimal detectable change was 6.01, 3.74 and 17.98, respectively. The presence of systematic error (p < 0.014), the significant difference between the measurements (p < 0.05), and the analysis of the Bland-Altman graph infer that CKCUEST is a discordant test with moderate to excellent reliability when used with adolescents.
CONCLUSION
The CKCUEST is a measurement with moderate to excellent reliability for adolescents.

背景
闭合动力链上肢稳定性测试（CKCUEST）已被提议作为评估上肢功能和稳定性的一种方法；然而，很少有研究支持在青少年中使用该测试。
目的
本研究的目的是调查青少年三项CKCUEST评分的组间可靠性和一致性，并确定该测试的临床测量值。
研究设计
重测可靠性。
方法
对25名健康青少年（男女均有）进行评估。受试者进行两次CKCUEST测试，测试间隔为一周。采用具有95%置信区间的组内相关系数（ICC）双向混合模型来确定组间可靠性。绘制Bland-Altman图以分析评估之间的一致性。通过单样本t检验评估系统误差的存在。使用配对样本t检验观察评估与重新评估之间的差异。显著性水平设定为0.05。计算测量标准误差和最小可检测变化。
结果
平均触碰次数评分、标准化评分和力量评分的组间可靠性分别为0.68、0.68和0.87，测量标准误差分别为2.17、1.35和6.49，最小可检测变化分别为6.01、3.74和17.98。系统误差的存在（p < 0.014）、测量之间的显著差异（p < 0.05）以及Bland-Altman图分析表明，CKCUEST在用于青少年时是一种一致性存在差异但可靠性为中等至优秀的测试。
结论
CKCUEST对青少年来说是一种可靠性为中等至优秀的测量方法。
