本研究的目的是测试是否使用新型压电振动鞋垫施加到脚底的感觉下振动噪声，可以显着改善感觉，增强平衡，并减少老年人的步态变异。我们还旨在确定振动噪声的最佳水平，以及治疗效果是否会持续，用户的感觉阈值是否会在一天中保持恒定。一项在3个不同日期对3种感觉下噪声刺激水平进行的随机单盲交叉研究。平衡步态实验室12名65 - 90岁的健康社区老年志愿者，能感觉到最大鞋垫振动。一种聚氨酯泡沫鞋垫，其压电致动器向脚底提供感觉下振动噪声刺激。平衡、步态和定时起身和行走测试。振动鞋垫显着提高了性能的定时上升和去测试，减少了姿势摆动的面积，并减少了时间的变化，步行在70%和85%的感觉阈值和整个一天的过程。振动感觉阈值在研究日内和研究日之间保持相对稳定。这项研究提供了一个概念的证据，即随机共振的原理，足底感觉系统的应用，使用一种新的低电压压电技术，可以改善平衡和步态的措施，与福尔斯。有效的振动噪声幅度范围为感觉阈值的70%至85%，并且可以每天设置一次。
The objective of this study was to test whether subsensory vibratory noise applied to the sole of the foot using a novel piezo-electric vibratory insole, can significantly improve sensation, enhance balance, and reduce gait variability in elderly people. We also aimed to determine the optimal level of vibratory noise, and whether the therapeutic effect would endure and the user’s sensory threshold would remain constant during the course of a day. A randomized single-blind crossover study of three subsensory noise stimulation levels on 3 separate days. Balance and gait laboratory 12 healthy community-dwelling elderly volunteers aged 65 – 90 years who could feel the maximum insole vibration. A urethane foam insole with the piezo-electric actuators delivering subsensory vibratory noise stimulation to the soles of the feet. Balance, gait, and timed up-and-go tests. The vibratory insoles significantly improved performance on the timed up-and-go test, reduced the area of postural sway, and reduced the temporal variability of walking at both 70% and 85% of the sensory threshold and throughout the course of a day. Vibratory sensation thresholds remained relatively stable within and across study days. This study provides proof of concept that the application of the principle of stochastic resonance to the foot sole sensory system using a new low voltage piezoelectric technology can improve measures of balance and gait that are associated with falls. Effective vibratory noise amplitudes range from 70% to 85% of the sensory thresholds and can be set once daily.
