To examine the feasibility and effectiveness of dual task (DT) exergaming to improve volitional balance control in older adults with mild cognitive impairment (MCI).
Ten older adults with MCI were examined at baseline (week-0) and post-training (week-5) on volitional balance control (maximum excursion of center of gravity, MXE [%]) while performing cognitive task (auditory clock test or letter number sequencing task) and on the NIH-motor and cognitive toolboxes. DT exergaming training lasted for 12 sessions which consisted of performing explicit cognitive tasks while playing the Wii-Fit balance games.
From pre- to post-training, MXE improved (p<0.05); however, cognitive accuracy (cognitive task) remained the same (p>0.05). Improvement in NIH motor and cognitive toolbox tests was observed post-training (p<0.05).
DT exergaming was associated to improvements in balance control under attention-demanding conditions in MCI. Future studies may focus on examining the efficacy of such training.
探讨双重任务（DT）运动游戏改善轻度认知障碍（MCI）老年人意志性平衡控制的可行性和有效性。
对10名患有MCI的老年人在基线（第0周）和训练后（第5周）进行检查，评估其在执行认知任务（听觉时钟测试或字母数字排序任务）时的意志性平衡控制（重心最大偏移量，MXE [%]），并使用美国国立卫生研究院运动和认知工具箱进行评估。DT运动游戏训练持续12节，包括在玩Wii Fit平衡游戏时执行明确的认知任务。
从训练前到训练后，MXE有所改善（p<0.05）；然而，认知准确性（认知任务）保持不变（p>0.05）。训练后观察到美国国立卫生研究院运动和认知工具箱测试有所改善（p<0.05）。
DT运动游戏与MCI患者在需要注意力的条件下平衡控制的改善有关。未来的研究可能集中在检验这种训练的效果上。
