DESCRIPTION (provided by applicant): Recent advances in the size and performance of micro-electromechanical systems (MEMS)-based inertial instruments enable the development of a prosthesis to provide information about head motion to vestibulopathic patients. One class of candidate users is individuals who have lost some or all vestibular function and would benefit from an artificial vestibular system to augment natural visual and nonvestibular proprioceptor balance cues. A second class of users is patients with vestibular lesions who experience asymmetric firing between bilateral vestibular receptor organs. Such patients may be able to take advantage of artificial vestibular cueing, particularly since head motion is likely to exacerbate their symptoms. A third class of users is patients with balance deficits due to vestibular disorders or stroke who are undergoing vestibular rehabilitation therapy. To evaluate the utility of the Vestibular Improvement Prosthesis (VIP) whose development is proposed herein, patients with bilateral vestibular deficits will perform computerized dynamic posturography and dynamic subjective visual vertical tests. The specific hypothesis tested is that these patients will perform posturographic and eccentric rotational testing significantly better using the proposed VIP. Based on these experiments and a "usability" analysis, a product prototype will be constructed and tested in Phase II.

描述（由申请人提供）：基于微机电系统（MEMS）的惯性仪器在尺寸和性能方面的最新进展使得能够开发假体来为前庭病患者提供有关头部运动的信息。一类候选用户是失去部分或全部前庭功能的个体，他们将受益于人工前庭系统来增强自然视觉和非前庭本体感受器平衡线索。第二类用户是患有前庭病变的患者，他们在双侧前庭受体器官之间经历不对称放电。此类患者可能能够利用人工前庭提示，特别是因为头部运动可能会加剧他们的症状。第三类用户是因前庭障碍或中风而患有平衡缺陷且正在接受前庭康复治疗的患者。 为了评估本文提出的前庭改善假体（VIP）的实用性，双侧前庭缺陷的患者将进行计算机动态姿势描记法和动态主观视觉垂直测试。测试的具体假设是，这些患者使用建议的 VIP 可以明显更好地执行体位描记和偏心旋转测试。根据这些实验和“可用性”分析，将在第二阶段构建和测试产品原型。
