Aside from typical symptoms such as dizziness and vertigo, persons with vestibular disorders often have cognitive and motor problems. These symptoms have been assessed in single-task condition. However, dual-tasks assessing cognitive-motor interference might be an added value as they reflect daily life situations better. Therefore, the 2BALANCE protocol was developed. In the current study, the test-retest reliability of this protocol was assessed.
The 2BALANCE protocol was performed twice in 20 healthy young adults with an in-between test interval of two weeks. Two motor tasks and five different cognitive tasks were performed in single and dual-task condition. Intraclass correlation coefficients (ICC), the standard error of measurement, and the minimal detectable difference were calculated.
All cognitive tasks, with the exception of the mental rotation task, had favorable reliability results (0.26≤ICC≤0.91). The dynamic motor task indicated overall substantial reliability values in all conditions (0.67≤ICC≤0.98). Similar results were found for the static motor task during dual-tasking (0.50≤ICC≤0.92), but were slightly lower in single-task condition (-0.26≤ICC≤0.75).
The 2BALANCE protocol was overall consistent across trials. However, the mental rotation task showed lowest reliability values.
除了头晕和眩晕等典型症状外，前庭障碍患者通常还存在认知和运动问题。这些症状在单任务条件下进行了评估。然而，评估认知-运动干扰的双重任务可能更有价值，因为它们能更好地反映日常生活情况。因此，开发了 2BALANCE 方案。本研究评估了该方案的重测信度。
20 名健康年轻成年人在两周的测试间隔内两次进行 2BALANCE 方案。在单任务和双重任务条件下进行了两项运动任务和五项不同的认知任务。计算了组内相关系数（ICC）、测量误差和最小可检测差异。
除心理旋转任务外，所有认知任务的可靠性结果均良好（0.26≤ICC≤0.91）。动态运动任务在所有条件下均显示出整体较高的可靠性值（0.67≤ICC≤0.98）。在双重任务条件下，静态运动任务也得到了类似的结果（0.50≤ICC≤0.92），但在单任务条件下略低（-0.26≤ICC≤0.75）。
2BALANCE 方案在整个试验中总体一致。然而，心理旋转任务的可靠性值最低。
