Reliability refers to the precision of an assessment, so it is a critical topic to take the right decisions related to health management. People usually perform several tasks at the same time in their daily life. The aim of this study was to examine the reliability of the 30-s chair stand test in people with type 2 Diabetes Mellitus (T2DM) with test-retest, with and without dual-task (motor + cognitive task).
Twenty-six subjects with T2DM and 30 subjects without T2DM performed the 30-s Chair Stand Test (30sCST) in which they must sit and stand as many times as possible in 30 s. They performed the test in the usual way (30sCST) and also with an additional cognitive task (30sCST-DT). A retest was conducted 7-14 days later.
Relative reliability was excellent in both groups (intraclass correlation coefficient > 0.9). In 30sCST-DT, relative reliability was high in the T2DM group (intraclass correlation coefficient > 0.7) and excellent in subjects without T2DM (intraclass correlation coefficient > 0.9).
The 30sCST and the 30sCST-DT tests are reliable tools for people with T2DM to measure changes after an intervention. The smallest real difference was 15% and 20% upper in the T2DM group in the 30sCST and 30sCST-DT tests, respectively.
可靠性是指评估的精确性，因此，做出与健康管理相关的正确决策是一个关键问题。人们在日常生活中通常同时执行多项任务。本研究旨在检验 2 型糖尿病（T2DM）患者在进行测试-重测时，同时进行和不进行双重任务（运动+认知任务）时 30 秒椅站测试的可靠性。
26 例 T2DM 患者和 30 例非 T2DM 患者进行 30 秒椅站测试（30sCST），要求他们在 30 秒内尽可能多地坐站。他们以通常的方式（30sCST）进行测试，也进行了附加的认知任务（30sCST-DT）。7-14 天后进行重测。
两组的相对可靠性均很高（组内相关系数>0.9）。在 30sCST-DT 中，T2DM 组的相对可靠性较高（组内相关系数>0.7），而非 T2DM 组的相对可靠性很高（组内相关系数>0.9）。
30sCST 和 30sCST-DT 测试是 T2DM 患者衡量干预后变化的可靠工具。T2DM 组在 30sCST 和 30sCST-DT 测试中的最小真实差异分别为 15%和 20%。
