基于足底压力的舌位触觉生物反馈平衡改善系统
A Plantar-pressure Based Tongue-placed Tactile Biofeedback System for Balance Improvement
摘要：
保持直立姿势是一项复杂的任务，它是通过整合来自视觉、前庭和体感系统的感觉信息来实现的。当这些感觉输入中的一个变得不可用和/或不准确和/或不可靠时，姿势控制通常会降级。解决这个问题的一种方法是通过经由替代感觉模态向中枢神经系统提供额外的感觉信息来补充和/或替代有限的/改变的/缺失的感觉信息。沿着这些思路，我们开发了一个原始的生物反馈系统[1]，其基本原理在于通过舌头放置的输出设备（舌头显示单元，“TDU”[2]）向用户提供与足底压力分布相关的补充感觉信息。本实验的目的是评估其在改善年轻健康成年人平衡方面的有效性。
英文摘要：
Maintaining an upright stance represents a complex task, which is achieved by integrating sensory information from the visual, vestibular and somatosensory systems. When one of these sensory inputs becomes unavailable and/or inaccurate and/or unreliable, postural control generally is degraded. One way to solve this problem is to supplement and/or substitute limited/altered/missing sensory information by providing additional sensory information to the central nervous system via an alternative sensory modality. Along these lines, we developed an original biofeedback system [1] whose underlying principle consists in supplying the user with supplementary sensory information related to foot sole pressure distribution through a tongue-placed output device (Tongue Display Unit, "TDU" [2]). The purpose of the present experiment was to assess its effectiveness in improving balance in young healthy adults.
