There are a limited number of tests for the assessment of shoulder and pelvic girdle stability. Reliable instruments are important to evaluate movement dysfunction at these joints in order to provide more objective parameters.
To evaluate the inter-day reliability of the Upper Body Test in young adults.
A reliability study was carried out with three assessments of the shoulder and pelvic girdle stability within 48-h intervals (Monday, Wednesday, and Friday). The OctoBalance® platform was used to perform the Upper Body Test in 31 active young adults (24.5±8 years). Intraclass Correlation Coefficient (ICC) two-way mixed model, Coefficient of Variation, and Bland-Altman plots were used to verify the reliability of the test. The standard error of measurement (SEM) and the minimum detectable difference (MDD) were calculated for clinical applicability.
The Intraclass Correlation Coefficient ranged from 0.87 to 0.94 - Featuring a mean difference of 0.89 (95%CI=-0.19-1.97) to left and 0.95 (95%CI=-0.38-2.27) for the right side, with a low variation coefficient (3.31-5.91%) between the second and third days of assessment. There was a statistically significant difference between the first assessment day and the other test sessions. The Bland-Altman analyses revealed low bias with scores within the limits of agreement. Minimum detectable difference scores were between 4.02 and 5.10, and standard error of measurement between 1.75 and 2.72, depending on the movement side.
The Upper Body Test presented good inter-day reliability for assessing the stability of the shoulder and pelvic girdle in young active healthy adults.
目前用于评估肩部和骨盆带稳定性的测试方法数量有限。可靠的仪器对于评估这些关节的运动功能障碍至关重要，因为这样可以提供更客观的参数。
评估年轻成年人的上体测试的日内可靠性。
对 31 名活跃的年轻成年人（24.5±8 岁）在 48 小时内（周一、周三和周五）进行了肩部和骨盆带稳定性的三次评估，使用 OctoBalance®平台进行上体测试。采用双变量混合模型的组内相关系数（ICC）、变异系数和 Bland-Altman 图来验证测试的可靠性。计算了测量标准误差（SEM）和最小可检测差异（MDD）以评估临床适用性。
组内相关系数范围为 0.87 至 0.94，左右侧的平均差值分别为 0.89（95%CI=-0.19-1.97）和 0.95（95%CI=-0.38-2.27），差异系数（3.31-5.91%）较低。第一天评估与其他测试日之间存在统计学差异。Bland-Altman 分析显示评分的偏差较小，在一致性界限内。最小可检测差异评分在 4.02 至 5.10 之间，取决于运动侧，测量标准误差在 1.75 至 2.72 之间。
上体测试在评估年轻活跃健康成年人的肩部和骨盆带稳定性方面具有良好的日内可靠性。
