Cognition and motor skills are interrelated throughout the aging process and often show simultaneous deterioration among older adults with cognitive impairment. Co-dependent training has the potential to ameliorate both domains; however, its effect on the gait and cognition of older adults with cognitive impairment has yet to be explored. The aim of this study is to compare the effects of the well-established single-modality cognitive computerized training program, CogniFit, with "Thinking in Motion (TIM)," a co-dependent group intervention, among community-dwelling older adults with cognitive impairment.
Employing a single-blind randomized control trial design, 47 community-dwelling older adults with cognitive impairment were randomly assigned to 8 weeks of thrice-weekly trainings of TIM or CogniFit. Pre- and post-intervention assessments included cognitive performance, evaluated by a CogniFit battery, as a primary outcome; and gait, under single- and dual-task conditions, as a secondary outcome.
CogniFit total Z scores significantly improved from baseline to post-intervention for both groups. There was a significant main effect for time [F (1, 44) = 17.43, p < .001, η = .283] but not for group [F (1, 44) = 0.001, p = .970]. No time X group interaction [F (1, 44) = 1.29, p = .261] was found. No changes in gait performance under single and dual-task performance were observed in both groups.
The findings show that single-modality (CogniFit) and co-dependent (TIM) trainings improve cognition but not gait in older adults with cognitive impairment. Such investigations should be extended to include various populations and a broader set of outcome measurements.

认知和运动技能在整个衰老过程中是相互关联的，并且经常在认知障碍的老年人中同时出现恶化。共同依赖训练有可能改善这两个领域；然而，其对认知障碍的老年人的步态和认知的影响尚未被探索。本研究的目的是比较既定的单一模式认知计算机训练程序 CogniFit 与“思维运动（TIM）”的效果，TIM 是一种共同依赖的小组干预措施，适用于认知障碍的社区居住老年人。
采用单盲随机对照试验设计，将 47 名认知障碍的社区居住老年人随机分配到 TIM 或 CogniFit 的每周三次训练 8 周。干预前后评估包括认知表现，使用 CogniFit 电池评估，作为主要结果；以及在单任务和双任务条件下的步态，作为次要结果。
CogniFit 总 Z 分数在两组中均从基线到干预后显著提高。时间有显著的主效应[F (1, 44) = 17.43, p < .001, η = .283]，但组间没有差异[F (1, 44) = 0.001, p = .970]。未发现时间与组之间的交互作用[F (1, 44) = 1.29, p = .261]。两组的单任务和双任务下的步态表现均无变化。
研究结果表明，单一模式（CogniFit）和共同依赖（TIM）训练可改善认知障碍老年人的认知能力，但不能改善步态。应将此类研究扩展到包括各种人群和更广泛的结果测量。
