Computerized game-based vestibular rehabilitation: assessment of feasibility and motor learning

基于计算机游戏的前庭康复:可行性评估和运动学习

基本信息

项目摘要

Damage to the vestibular system is a common problem that often leads to substantial disability. For most cases, there is no effective medication to restore vestibular function. Instead, the mainstay of treatment is vestibular rehabilitation to promote central motor learning that will enhance impaired vestibular reflexes and compensate for the vestibular deficit. Vestibular therapy consists of a program of exercises that are performed at home and in the clinic, supervised by a trained vestibular therapist. Gaze stability exercises target the vestibulo-ocular reflex and improve vision during head movement; balance exercises help to restore good postural control. Although vestibular therapy is effective, there are several key limitations as it is currently practiced. First, the difficulty of exercises cannot be precisely calibrated to each patient's specific level of impairment. Second, compliance with therapy cannot be easily monitored. Finally, standard exercises may not be sufficiently engaging to encourage continued practice. The objective of this project is to test the feasibility of a customized interactive vestibular game for gaze stability exercises. The game is based on a visual discrimination task that tests visual acuity during rotations of the head. The difficulty of the task can be customized and adjusted incrementally based on the patient's initial level of function and progress over time with treatment. There are two aims of this pilot study. The first aim will test the ability of the game to induce plasticity in the vestibulo-ocular reflex in healthy individuals with normal vestibular function. The approach will be based on prior studies of vestibular adaptation, in which a mismatch of vestibular (head motion) and visual (motion of the scene being viewed) inputs leads to a change in the gain of the vestibulo-ocular reflex. In the same group of subjects, the change in VOR gain provoked by an incremental increase in the degree of visual-vestibular mismatch will be compared to that induced by the more traditional approach of single-step adaptation. The hypothesis is that the game will lead to a change in vestibulo-ocular reflex gain, and that this change will be larger with the incremental strategy. The second aim will be to test the feasibility and playing experience of the vestibular game in a group of veterans with peripheral vestibular hypofunction, who are undergoing or who have recently completed standard vestibular rehabilitation therapy. Each patient will play the game and will provide feedback of their experience. We will also record the same physiological data (vestibulo-ocular reflex gain before and after playing) to assess short term motor response. The patients will play the game once a week for four sessions each; this will provide us with preliminary data regarding improvements in gaze stability over time. The data from this aim will support a future application for a multisession clinical trial of our game in comparison to conventional therapy.
前庭系统的损伤是一个常见的问题,通常会导致严重的残疾。在大多数情况下, 目前还没有有效的药物来恢复前庭功能。相反,治疗的主要方法是前庭。 促进中枢运动学习的康复将增强受损的前庭反射和补偿 前庭缺陷症。前庭疗法包括在家中进行的一系列练习和 在诊所,由训练有素的前庭治疗师监督。凝视稳定性练习的目标是前庭-眼睛 在头部运动过程中反射和改善视力;平衡练习有助于恢复良好的姿势控制。 虽然前庭疗法是有效的,但目前它有几个关键的局限性。首先, 运动的难度不能根据每个患者的具体损伤程度进行精确的校准。第二, 治疗依从性不容易被监测。最后,标准练习可能还不够 参与以鼓励继续练习。该项目的目标是测试定制的 用于凝视稳定练习的互动前庭游戏。这款游戏基于一项视觉辨别任务, 测试头部旋转时的视力。任务的难度可以定制和调整 根据患者最初的功能水平和随时间推移的治疗进展而递增。 这项初步研究有两个目的。第一个目标是测试游戏的能力,以诱导 前庭功能正常的健康人的前庭-眼反射。该方法将基于 先前关于前庭适应的研究,其中前庭(头部运动)和视觉(视觉运动)不匹配 正在观看的场景)输入导致前庭-眼睛反射的增益改变。在同一组中 受试者,由视觉前庭程度的增加引起的VOR增益的变化 失配将与更传统的单步适应方法引起的失配进行比较。这个 假设游戏将导致前庭-眼睛反射增益的变化,并且这种变化将是 增量战略的规模更大。 第二个目标是测试前庭游戏的可行性和游戏体验 有外周前庭功能减退的退伍军人,正在接受或最近完成标准 前庭康复疗法。每个患者都将玩这个游戏,并提供他们的经验反馈。 我们还将记录相同的生理数据(比赛前和比赛后的前庭-眼睛反射增益)以评估 短期运动反应。患者将每周玩一次游戏,每次四次;这将提供 美国有关于随着时间的推移凝视稳定性改善的初步数据。来自这一目标的数据将支持 与传统疗法相比,我们的游戏将在未来进行多疗程临床试验。
