This study investigated whether real-time biofeedback of angular trunk displacement could alter balance performance among healthy older and young adults. Healthy community-dwelling older adults (n=32) and healthy young adults (n=32) were included in the randomized control trial study. The intervention group received combined vibrotactile, auditory and visual biofeedback of angular trunk displacement in real-time during training on a battery of static and dynamic balance tasks and during the subsequent post-training balance re-assessment. The control group received balance training and were re-assessed in the absence of real-time biofeedback of their trunk displacement. The 90% range of angular trunk displacement was calculated for each balance task pre- and post-training. Significant age-related differences were observed independent of the intervention. Biofeedback intervention significantly changed the angular displacement of the trunk for both young and older participants on a number of balance tasks compared to control treatment (40-60% reduction in angular displacement). In some cases, biofeedback influenced balance in older adults, but not younger adults.
本研究旨在探讨实时躯干角度位移生物反馈是否可以改变健康老年人和年轻人的平衡表现。本研究纳入了 32 名健康的社区居住老年人和 32 名健康的年轻人，采用随机对照试验研究。干预组在一系列静态和动态平衡任务的训练过程中以及随后的平衡后评估中实时接受躯干角度位移的振动触觉、听觉和视觉联合生物反馈，而对照组则在没有实时躯干位移生物反馈的情况下接受平衡训练和评估。在训练前后计算了每个平衡任务的躯干角度位移 90%范围。干预组和对照组都观察到了与年龄相关的显著差异。与对照组相比，生物反馈干预显著改变了年轻和年长参与者在多项平衡任务中的躯干角度位移（角度位移减少 40-60%）。在某些情况下，生物反馈影响了老年人的平衡，但对年轻人没有影响。
