目前使用的临床平衡测试不能预测帕金森病（PD）的福尔斯，可能是因为它们探测的是相当孤立的姿势控制“成分”。多任务测试（MTT）是一种新的平衡测试，同时评估姿势控制的多个组成部分。我们研究了MTT是否可以检测PD患者的姿势异常。50名年轻对照组（平均年龄27.6岁）、20名老年对照组（平均年龄62.5岁）和20名PD患者（平均年龄61.8岁，平均Hoehn-Yahr分期2.2）参与了研究。MIT由八个独立的任务组成，这些任务的复杂性不断增加，并按顺序执行。这些任务由几个运动组件（站立，行走，避开障碍物，触摸地板，转身和坐下）和一个认知组件（回答系列问题）组成。四个额外的组成部分包括携带一个空的或加载托盘，穿着滑鞋，并减少照明。每个任务中的所有组成部分必须同时或直接顺序执行。错误被定义为犹豫（减慢性能）或块（完全停止），这是分别为执行运动和认知组件。性能的速度并没有被强调，但我们确实测量了完成所有任务所需的时间。所有受试者都进行了完整的MTT测试，除了一个由7名患者和7名老年对照组成的亚组，他们进行了缩短版本，只有8个顺序任务中的3个（简单，中间和最困难）。三组之间产生运动成分犹豫或阻滞的受试者数量不同[双向重复测量MANOVA，F（2，7）=20.56; P
The clinical balance tests presently used cannot predict falls in Parkinson's disease (PD), perhaps because they probe fairly isolated "components" of postural control. The Multiple Tasks Test (MTT) is a new balance test that simultaneously assesses multiple components of postural control. We investigated whether this MTT can detect postural abnormalities in PD patients. Fifty young controls (mean age 27.6 years), 20 elderly controls (mean age 62.5 years), and 20 PD patients (mean age 61.8 years, mean Hoehn and Yahr stage 2.2) participated. The MIT consisted of eight separate tasks of increasing complexity, which were executed sequentially. These tasks were composed of several motor components (standing up, walking, avoiding obstacles, touching the floor, turning around, and sitting down) and one cognitive component (answering serial questions). Four additional components included carry ing an empty or loaded tray, wearing slippery shoes, and reduced illumination. All components within each task had to be performed simultaneously or directly sequentially. Errors were defined as Hesitations (slowed performance) or Blocks (complete cessation), which were scored separately for execution of the motor and cognitive components. Speed of performance was not stressed, but we did measure the time taken to complete all tasks. The complete MTT was performed by all subjects, except for a subgroup of seven patients and seven elderly controls who performed a shortened version, with only three of the eight sequential tasks (simple, intermediate, and most difficult). The number of subjects that produced Hesitations or Blocks for the motor components differed between the three groups [two-way repeated measures MANOVA, F(2,7)=20.56; P
