目前正在研究体位摇摆的视觉生物反馈作为一种治疗技术，以减少特定患者群体的体位不稳定性。在临床环境中确定这种疗法的疗效之前，必须描述正常人群进行静态和动态平衡训练练习的表现曲线。两组正常受试者在每日和每周动态平衡练习方案中进行评估，使用视觉反馈他们的重心（COG）和理论稳定性极限。在治疗前和治疗后的评估中，通过睁眼、闭眼和COG的视觉反馈来测量中心位置的静态稳定性。从治疗前到治疗后的评估中，没有观察到任何这些变量的显著变化；两组的得分也没有差别。动态变量在治疗前到治疗后评估和整个治疗过程中进行评估。每一种方案都要求受试者用他们的COG在电脑屏幕上跟踪代表他们稳定极限75%的目标。评估了COG光标从一个目标移动到另一个目标所需的时间和准确性，以及到达目标时的身体摇摆。从治疗前到治疗后，两组的过渡时间和摇摆面积均显著减少（p < 0.01），仅每日治疗组的路径误差显著减少。各组间无显著差异。（摘要删节250字）
Visual biofeedback of postural sway is currently being investigated as a therapeutic technique to reduce postural instability in selected patient populations. Before the efficacy of this type of therapy can be determined in a clinical setting, the performance curves of a normal population doing the static and dynamic balance training exercises have to be delineated. Two groups of normal subjects were evaluated during a daily and weekly protocol of dynamic balance exercises using visual feedback of their center of gravity (COG) and theoretical limits of stability. Static stability in a central position was measured with eyes open, eyes closed, and with visual feedback of the COG in a pre-therapy to post-therapy assessment. No significant change was observed in any of these variables from the pre-therapy to the post-therapy evaluation; as well there was no difference between the scores of both groups. Dynamic variables were evaluated in both a pre-therapy to post-therapy assessment, and over the course of therapy. Each of these protocols required the subjects to track targets representing 75% of their limits of stability on a computer screen with their COG. The time taken and the accuracy to move the COG cursor from target to target, as well as the body sway upon reaching the target were evaluated. Transition time and sway area both decreased significantly (p less than 0.01) from the pre-therapy to the post-therapy assessment for both groups, with path error decreasing significantly for the daily therapy group only. No significant difference was demonstrated between groups.(ABSTRACT TRUNCATED AT 250 WORDS)
