跌倒是老年人受伤的常见原因，与年龄相关的感觉系统衰退与跌倒风险增加有关。前庭系统对于维持平衡和支持安全活动尤为重要，而衰老与前庭终末器官功能的下降有关。然而，很少有研究调查了前庭知觉敏感性的潜在年龄相关差异或其与姿势稳定性的关系。在这里，我们使用自适应阶梯程序来测量19名健康oa和18名健康年轻人（ya）的检测和区分阈值，方法是在黑暗中在运动平台上让参与者进行被动的起伏（线性上下平移）和俯仰（前后倾斜旋转）运动。我们还检查了参与者在不同站立平衡条件下的姿势稳定性。进一步研究了这些姿势测量和前庭知觉阈值之间的关系。最终，与YAs相比，OAs表现出更大的起伏和音调检测阈值，并且更大的感知阈值与更大的姿势摇摆相关，但仅限于OAs。总的来说，这些结果表明，前庭知觉敏感性随着年龄的增长而下降，这种下降与较差的姿势稳定性有关。未来的研究可以考虑这些结果在发展美洲地区预防跌倒的筛查工具中的潜在适用性。
Falls are a common cause of injury in older adults (OAs), and age-related declines across the sensory systems are associated with increased falls risk. The vestibular system is particularly important for maintaining balance and supporting safe mobility, and aging has been associated with declines in vestibular end-organ functioning. However, few studies have examined potential age-related differences in vestibular perceptual sensitivities or their association with postural stability. Here we used an adaptive-staircase procedure to measure detection and discrimination thresholds in 19 healthy OAs and 18 healthy younger adults (YAs), by presenting participants with passive heave (linear up-and-down translations) and pitch (forward–backward tilt rotations) movements on a motion-platform in the dark. We also examined participants’ postural stability under various standing-balance conditions. Associations among these postural measures and vestibular perceptual thresholds were further examined. Ultimately, OAs showed larger heave and pitch detection thresholds compared to YAs, and larger perceptual thresholds were associated with greater postural sway, but only in OAs. Overall, these results suggest that vestibular perceptual sensitivity declines with older age and that such declines are associated with poorer postural stability. Future studies could consider the potential applicability of these results in the development of screening tools for falls prevention in OAs.
