The present study highlights the effects of the dual-task cognitive-gait intervention (CGI) on working memory and gait functions in older adults with a history of falls. Thirteen older adults with a history of falls were recruited from local community centers and randomly stratified into either the control (n = 5) or experimental (n = 8) group. The experimental group received the dual-task cognitive-motor intervention involving simultaneous motor (walking) and cognitive (memory recall) task whereas the control group received a placebo treatment (walking with simple music). The intervention was provided 30 minutes per session, over a 6-week period. Memory measures included a combination of word recall and arithmetic task. Gait function measures included velocity and center of pressure (COP) stability. Non-parametric tests were used at p < 0.05. The experimental group showed a greater memory performance than the control (p < 0.05). However, no significant intervention-related changes in gait velocity and stability were observed. Our findings provide the first evidence in literature to demonstrate that the long-term dual-task cognitive-motor intervention improved memory of older adults with a history of falls under the dual cognitive motor task condition.
本研究强调了双任务认知步态干预（CGI）对有跌倒史的老年人工作记忆和步态功能的影响。从当地社区中心招募了13名有跌倒史的老年人，并将他们随机分层分为对照组（n = 5）或实验组（n = 8）。实验组接受双任务认知运动干预，包括同时进行运动（行走）和认知（记忆回忆）任务，而对照组接受安慰剂治疗（伴着简单音乐行走）。干预为期6周，每次30分钟。记忆测量包括单词回忆和算术任务的组合。步态功能测量包括速度和压力中心（COP）稳定性。使用p < 0.05的非参数检验。实验组的记忆表现优于对照组（p < 0.05）。然而，未观察到与干预相关的步态速度和稳定性的显著变化。我们的研究结果提供了文献中的首个证据，证明长期双任务认知运动干预在双认知运动任务条件下改善了有跌倒史老年人的记忆。
