Aging often results in a decline in somatosensory function, and such changes are associated with diminished motor performance. Input noise can enhance sensory and motor function through a mechanism known as stochastic resonance (SR). This paper describes the development and testing of a new vibrating shoe to possibly assist the elderly patients in controlling their balance and decreasing their falling risks.
The new vibrating shoe was evaluated to ascertain its ability to generate appropriate random and nonlinear vibrations. The vibratory shoe performance in two young subjects with decreased foot sensation and two elderly subjects in different static and dynamic balance situations was also evaluated. The postural control, expressed by the stability index (SI), was significantly affected by SR in the older subjects.
The vibrating motors could be recommended as a suitable solution for dynamic balance situations. Moreover, the new vibrating shoe could improve the age-related balance impairments in elderly subjects with balance deficiencies and others with impaired foot sensations. Implications for rehabilitations Older adults exhibited decreased postural stability. Noise signal improves sensation and proprioception in older people. New shoe with vibrating motors can operate in different dynamic situations.
衰老常常导致体感功能下降，而这种变化与运动表现的减退有关。输入噪声可通过一种称为随机共振（SR）的机制增强感觉和运动功能。本文描述了一种新型振动鞋的研发与测试，其目的在于可能帮助老年患者控制平衡并降低跌倒风险。
对新型振动鞋进行评估，以确定其产生适当随机和非线性振动的能力。还评估了该振动鞋在两名足部感觉减退的年轻受试者以及两名处于不同静态和动态平衡状况的老年受试者中的性能表现。以稳定性指数（SI）表示的姿势控制在老年受试者中受到随机共振的显著影响。
振动电机可被推荐为动态平衡状况的合适解决方案。此外，新型振动鞋可改善存在平衡缺陷的老年受试者以及其他足部感觉受损者与年龄相关的平衡障碍。对康复的启示：老年人表现出姿势稳定性下降。噪声信号可改善老年人的感觉和本体感觉。带有振动电机的新型鞋子可在不同动态状况下运行。
