This study aimed to investigate the effectiveness of dual-task training (DTT) compared to single-task training (STT), on gait parameters in elderly patients with mild dementia (MD). Twenty-four elderly patients with MD were randomly assigned to the DTT ( = 13) or the STT group ( = 11). The DTT group performed a specific cognitive-motor DTT, while the STT group received only motor task training. Both training sessions lasted 8 weeks, with a frequency of 3 days per week, and the cognitive functions and gait parameters were measured. A statistically significant interaction effect was found between the two groups in stride length, stride velocity, cadence, step length, swing phase, stance phase, and double support phase ( < 0.05). After 8 weeks, the DTT group showed significant improvement in spatiotemporal parameters, except for the kinematic parameters ( < 0.05). In the between-group analysis, the DTT group showed more improvement than the STT group in stride velocity, step length, swing phase, stance phase, and double support ( < 0.05). These findings suggest that improvements in spatiotemporal gait parameters after DTT are reported in patients with MD. Our results can guide therapists to include dual tasks in their gait rehabilitation programs for the treatment of mild dementia.
本研究旨在调查与单任务训练（STT）相比，双任务训练（DTT）对轻度痴呆（MD）老年患者步态参数的有效性。24名患有MD的老年患者被随机分配到DTT组（n = 13）或STT组（n = 11）。DTT组进行特定的认知 - 运动双任务训练，而STT组仅接受运动任务训练。两个训练阶段均持续8周，每周进行3天，同时测量认知功能和步态参数。在步长、步速、步频、步幅、摆动期、支撑期和双支撑期方面，两组之间发现了具有统计学意义的交互作用（P < 0.05）。8周后，除运动学参数外，DTT组在时空参数方面有显著改善（P < 0.05）。在组间分析中，DTT组在步速（P < 0.05）、步幅、摆动期、支撑期和双支撑期方面比STT组有更多改善。这些发现表明，MD患者在进行DTT后时空步态参数有所改善。我们的结果可以指导治疗师在其步态康复计划中纳入双任务，以治疗轻度痴呆。
