Development of the Dual-task Walking for Community Elderly with mild cognitive impairment

受试者，208老年人居住在该地区，进行了测试，他们的能力，同时进行认知任务（DTW-C：双任务步行的社区老年人，我们已经设计）。具体来说，受试者被指示在传感器垫上以正常速度行走5米的距离，同时以相反的顺序重复给定的随机排列的2位数和3位数。例如，在一个实施例中，4-5→5-4、7-9→9-7等）。该测试以3个阶段进行，从没有认知任务开始，然后以如上所述的相反顺序重复两位数，然后三位数。结果表明，认知任务和行走的双重任务的性能之间的中间强相关性。然而，也有人指出，该测试缺乏区分效度（e。例如，在一个实施例中，坠落事件）。

The subjects, 208 aged individuals residing in the area, were tested for their capacity to walk while undergoing a cognitive task(DTW-C : dual task walking for the community elderly that we have designed). Specifically, the subjects were instructed to walk at normal speed for a distance of 5 meters on a sensor mat, while repeating given randomly arranged 2-and 3-digit numbers in reverse order(e. g., 4-5→5-4, 7-9→9-7, etc.). The test was run in 3 stages starting with no cognitive task, followed by repeating two, then three digit numbers in reverse order as described above. The results indicated an intermediate to strong correlation between the performance of a dual task of cognitive task and walking. It was also indicated, however, that the test lacks discriminating validity(e. g., the event of falling).
