Vestibular reflexes have traditionally formed the cornerstone of vestibular evaluation, but perceptual tests have recently gained attention for use in research studies and potential clinical applications. However, the unknown reliability of perceptual thresholds limits their current importance. This is addressed here by establishing the test-retest reliability of vestibular perceptual testing.
Perceptual detection thresholds to earth-vertical, yaw-axis rotations were collected in 15 young healthy people. Participants were tested at two time intervals (baseline, 5 to 14 days later) using an adaptive psychophysical procedure.
Thresholds to 1 Hz rotations ranged from 0.69 to 2.99°/s (mean: 1.49°/s; SD: 0.63). They demonstrated an excellent intraclass correlation (0.92; 95% confidence interval: 0.77 to 0.97) with a minimum detectable difference of 0.45°/s.
The excellent test-retest reliability of perceptual vestibular testing supports its use as a research tool and motivates further exploration for its use as a novel clinical technique.
传统上,前庭反射一直是前庭评估的基石,但感知测试最近因其在研究和潜在临床应用中的应用而受到关注。然而,感知阈值的未知可靠性限制了它们目前的重要性。本研究通过建立前庭感知测试的重测信度来解决这一问题。
在 15 名年轻健康人中收集了对地球垂直、偏航轴旋转的感知检测阈值。参与者在两个时间间隔(基线,5 至 14 天后)使用自适应心理物理程序进行测试。
1 Hz 旋转的阈值范围为 0.69 至 2.99°/s(平均值:1.49°/s;标准差:0.63)。它们表现出极好的组内相关(0.92;95%置信区间:0.77 至 0.97),最小可检测差异为 0.45°/s。
感知前庭测试的重测信度极好,支持将其用作研究工具,并促使进一步探索其作为一种新的临床技术的应用。
