Training with a slow and sustained mechanical load, such as standing on one leg, is an effective method for improving balance and increasing lower-extremity strength. Also, visual feedback during motor learning is important in facilitating efficient postural responses and balance skills. In this study, a custom-made visual feedback device was invented to provide the training modality and program based on single-leg standing combined with augmented visual feedback training. This study aimed to investigate the effects of visual feedback training using the custom-made visual feedback device on balance and functional lower-extremity strength in older adults.
Thirty-four independent older adults were randomly allocated to a training group (TG) and a control group (CG). The participants in the TG received training with the custom-made visual feedback device. The training duration was three sessions per week, for four weeks. The participants in the CG continued their routine activities. Balance (static and dynamic balances, and balance confidence) and functional lower-extremity strength were assessed pre- and post-training.
Improvements in static balance (sway velocity and limit of balance during one-leg standing with eyes open) and dynamic balance (directional control of limits of stability in the backward direction) were found after training in the TG compared with the CG. No significant differences in balance confidence or functional lower-extremity strength were found between groups after training.
In older adults, training with a custom-made visual feedback device could be used to improve both static and dynamic balances, but not balance confidence and functional lower-extremity strength.
使用缓慢而持续的机械负荷进行训练，例如单腿站立，是改善平衡和增强下肢力量的有效方法。此外，在运动学习过程中提供视觉反馈对于促进有效的姿势反应和平衡技能很重要。在这项研究中，发明了一种定制的视觉反馈设备，以提供基于单腿站立结合增强视觉反馈训练的训练模式和程序。本研究旨在探讨使用定制的视觉反馈设备进行视觉反馈训练对老年人平衡和功能性下肢力量的影响。
34 名独立的老年人被随机分配到训练组（TG）和对照组（CG）。TG 组的参与者接受了定制视觉反馈设备的训练。训练持续时间为每周 3 次，为期 4 周。CG 组的参与者继续进行日常活动。在训练前后评估平衡（静态和动态平衡以及平衡信心）和功能性下肢力量。
与 CG 相比，TG 组在训练后静态平衡（单腿站立睁眼时的摇摆速度和平衡极限）和动态平衡（后向稳定性极限的方向控制）方面有所改善。训练后，两组在平衡信心或功能性下肢力量方面均无显著差异。
在老年人中，使用定制的视觉反馈设备进行训练可以改善静态和动态平衡，但不能改善平衡信心和功能性下肢力量。
