项目摘要

It is difficult to detect the disability in activities of daily living (ADL) in patients with unilateral vestibular disorders using the current methods. The purpose of this research was to make it possible detecting patients' disabilities in ADL by 3-dimensional motion analysis. In this research, we focused on the standing posture with two kinds of manner and stepping motion in the patients with unilateral vestibular disorders and healthy subjects.Small reflective markers were attached on the right and left sides of subjects' head, shoulder and trochanter. The performance was recorded with two CCD cameras. The position of the marker was detected using computer. Healthy subjects and patients were instructed to do three kinds of performances as follows. Condition 1: standing with putting one foot in front of the other for 30 seconds with the eyes closed Condition 2: standing on one foot with the eyes closed for 30 seconds Condition 3: stepping with the eyes closed for 30 secondsWe measured the rotation angle and/or deviation angle of the head, shoulder and trochanter. We could find distinct difference between patients and healthy subjects. Patients showed the remarkable correlation between head and trochanter in rotation angle and/or deviation angle in condition 1 and condition 2. Similarly, patients showed the high correlation between head and shoulder in rotation angle in condition 3. On the other hand, healthy subjects did not show the definite correlation between head and other parts of the body in all three conditions. In this study, three dimensional motion analysis was useful for detecting abnormalities in the performance of the patients with unilateral vestibular disorders.

单侧前庭功能障碍患者的日常生活活动能力(ADL)障碍难以用现有的方法进行检测。本研究的目的是通过三维运动分析来检测患者的日常生活活动能力障碍。本研究以单侧前庭功能障碍患者和健康受试者为研究对象，在受试者头部、肩部和粗隆两侧各贴上微小的反光标记，观察受试者站立时的两种姿势和步态动作。这场表演是用两个CCD摄像机记录下来的。用计算机检测标记物的位置。健康受试者和患者被指导做如下三种表演。条件1：闭眼一只脚向前站立30秒；条件2：一只脚闭眼站立30秒；条件3：闭眼行走30秒。我们可以发现患者和健康人之间有明显的差异。在状态1和状态2中，患者在旋转角度和/或偏转角上显示出显著的头与转子的相关性。同样，在状态3中，患者的头和肩在旋转角度上显示出高度的相关性。另一方面，健康受试者在三种状态下都没有显示出头与身体其他部位之间的明确相关性。在这项研究中，三维运动分析有助于检测单侧前庭疾病患者的表现异常。
