本文的目的是 (1) 对使用两种常用助行器（标准助行器和滚动助行器）行走的注意力需求进行初步检查，以及 (2) 向物理治疗界介绍双任务方法。 五名熟悉助行器正确使用方法的受试者和五名不了解助行器正确使用方法的受试者参与了这项研究。 每个受试者完成了实验的三个阶段：（1）仅执行反应时间（RT）任务； (2) 仅执行每项步行任务； (3)结合RT任务执行每个行走任务，构成双任务条件。 研究结果表明，通过滚动助行器或标准助行器辅助行走需要高度集中注意力。 更重要的是，使用标准助行器行走时似乎需要更大的注意力。 这些结果是针对使用这些助行器时所需的步态修改和准确性要求进行讨论的。 强调了双任务方法作为解决临床导向问题的研究工具的有用性，并讨论了该方法对于临床治疗师的一些潜在应用。
The purposes of this article are (1) to provide a preliminary examination of the attentional demands of ambulating with two commonly prescribed walking aids (a standard walker and a rolling walker) and (2) to introduce the dual-task methodology to the physical therapy community. Five subjects familiar with the appropriate use of the walker and five subjects uninformed as to the correct use of the walkers participated in the study. Each subject completed the three phases of the experiment: (1) performing the reaction time (RT) task only; (2) performing each of the walking tasks only; and (3) performing each of the walking tasks in conjunction with the RT task, which constituted the dual-task conditions. The findings indicated that walking aided by either the rolling walker or the standard walker was highly attention demanding. More importantly, it appears that greater attentional demand was required when ambulating with the standard walker. These results are discussed with respect to the gait modifications and accuracy demands required when using these walkers. The usefulness of the dual-task methodology as a research tool for addressing clinically oriented questions is emphasized, and some potential applications of this methodology for the therapist within the clinic are discussed.
