[Purpose] The aim of this study was to investigate the effects of tempo changes in rhythmic auditory stimulation (RAS) on gait in stroke patients. [Subjects] Forty-one chronic stroke patients who had had a stroke with more than 6 months previously were recruited for this study. [Methods] All participants were asked to walk under 5 different conditions in random order: (1) no RAS (baseline); (2) baseline-matched RAS (0%); and (3) -10%, (4) +10%, and (5) +20% of the baseline. A GAITRite system was used to evaluate the spatial and temporal parameters of gait. [Results] Compared with under the RAS 0% conditions, the gait velocity, cadence, and stride length on the affected side were significantly decreased under the RAS -10% conditions. Gait velocity and cadence were significantly improved, but gait symmetry was significantly decreased under the RAS +10% and +20% conditions compared with under the RAS 0% conditions. [Conclusion] A faster RAS tempo significantly improved gait velocity and cadence, and applying RAS significantly improved the gait symmetry of stroke patients.
[目的]本研究旨在探讨节奏性听觉刺激（RAS）中的节奏变化对中风患者步态的影响。[对象]本研究招募了41名6个月前曾患中风的慢性中风患者。[方法]要求所有参与者在5种不同条件下随机行走：（1）无RAS（基线）；（2）与基线匹配的RAS（0%）；以及（3）-10%、（4）+10%和（5）+20%的基线。使用GAITRite系统评估步态的空间和时间参数。[结果]与RAS 0%条件下相比，RAS -10%条件下患侧的步态速度、步频和步幅显著降低。与RAS 0%条件下相比，RAS +10%和+20%条件下步态速度和步频显著提高，但步态对称性显著降低。[结论]更快的RAS节奏显著提高了步态速度和步频，应用RAS显著改善了中风患者的步态对称性。
