研究表明，对下肢关节进行一分钟的类似噪音的电刺激（ES）可以稳定单腿站立（OS），这可能是由于噪音增强的关节本体感觉。为了证明这一发现的实际效用，我们评估了相对稳定且通常用于日常活动的双足站立（BS）是否也通过相同的ES方法稳定。12名志愿者保持安静的BS，有或没有无法察觉的类似噪音的膝关节ES。结果表明，ES对前后方向足部压力中心的平均振幅、峰间振幅和标准差有显著的衰减作用（P<0.05）。这些结果表明，BS也可以通过膝关节的不可感知的噪声样ES来稳定。
Studies have shown that a minute, noise-like electrical stimulation (ES) of a lower limb joint stabilizes one-legged standing (OS), possibly due to the noise-enhanced joint proprioception. To demonstrate the practical utility of this finding, we assessed whether the bipedal stance (BS), relatively stable and generally employed in daily activities, is also stabilized by the same ES method. Twelve volunteers maintained quiet BS with or without an unperceivable, noise-like ES of a knee joint. The results showed that the average amplitude, peak-to-peak amplitude, and standard deviation of the foot center of pressure in the anteroposterior direction were significantly attenuated by the ES (P<0.05). These results indicate that the BS also can be stabilized by an unperceivable, noise-like ES of a knee joint.
