Background

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.

Objective

To evaluate the inter-day reliability of the Upper Body Test in young adults.

Methods

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_2,2) 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_95%) were calculated for clinical applicability.

Results

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.

Conclusion

The Upper Body Test presented good inter-day reliability for assessing the stability of the shoulder and pelvic girdle in young active healthy adults.

成人上半身测试对肩膀和骨盆带稳定性的日间可靠性。

背景

评估肩部和骨盆带稳定性的测试数量有限。可靠的仪器对于评估这些关节的运动功能障碍很重要，以便提供更多客观的参数。

目的

为了评估年轻人上半身测试的日间可靠性。

方法

在48小时间隔内（星期一，星期三和星期五）对肩膀和骨盆带的稳定性进行了三项评估，从而进行了可靠性研究。OctoBalance®平台用于对31位活跃的年轻人（24.5±8岁）进行上身测试。类内相关系数（ICC _2,2）双向混合模型，变异系数和Bland-Altman图用于验证测试的可靠性。计算出标准测量误差（SEM）和最小可检测差异（MDD _95％），以用于临床。

结果

类内相关系数的范围从0.87到0.94 –左侧的平均差为0.89（95％CI = -0.19–1.97），右侧的平均差为0.95（95％CI = -0.38–2.27），变异系数低在评估的第二天和第三天之间（3.31-5.91％）。在第一个评估日和其他测试日之间存在统计学上的显着差异。布兰德·奥特曼（Bland-Altman）分析显示，偏差偏低且得分在协议范围内。最小可检测差异得分在4.02和5.10之间，测量的标准误差在1.75和2.72之间，具体取决于运动侧。

结论

该上身测试呈现良好的日间可靠性评估年轻活跃的健康成人的肩膀和骨盆带的稳定性。
