背景:轻度认知障碍(MCI)病例的增加强调了寻找有效方法来减缓其进展的紧迫性。鉴于目前预防或治疗这种恶化的早期阶段的药物选择的有效性有限,非药物替代品尤其相关。
目的:评估基于沉浸式虚拟现实(VR)的认知运动干预的有效性,该干预模拟日常生活活动(ADL)对认知功能的影响及其对抑郁症的影响以及MCI患者进行此类活动的能力。
方法:34名老年人(男性,将MCI女性)随机分为实验组(n=17;75.41±5.76)或对照组(n=17;77.35±6.75)。两组都接受了运动训练,通过有氧运动,群体中的平衡和抵抗活动。随后,实验组接受基于VR的认知训练,对照组接受传统的认知训练。认知功能,抑郁症,使用西班牙语版本的蒙特利尔认知评估(MoCA-S)评估了进行日常生活活动(ADL)的能力,老年抑郁量表(SGDS-S),以及6周干预前后的日常生活工具活动(IADL-S)(共12次40分钟)。
结果:组间比较未发现认知功能或老年抑郁症的显著差异。认知功能和老年抑郁症的组内效应在两组中均显著(p<0.001),具有较大的效果尺寸。在评估其在ADL中的表现时,任何一组都没有统计学上的显着改善(对照,p=0.28;实验,p=0.46)如预期。实验组的完成率(82.35%)高于对照组(70.59%)。同样,实验组的参与者在申请中达到了较高的难度,并且需要更少的时间来完成每个级别的任务。
结论:双重干预的应用,在基于沉浸式VR的认知任务之前通过运动训练被证明是改善MCI患者认知功能和减少抑郁的有益非药物策略。同样,对照组受益于这种双重干预,有统计学意义的改善.

BACKGROUND: The increase in cases of mild cognitive impairment (MCI) underlines the urgency of finding effective methods to slow its progression. Given the limited effectiveness of current pharmacological options to prevent or treat the early stages of this deterioration, non-pharmacological alternatives are especially relevant.
OBJECTIVE: To assess the effectiveness of a cognitive-motor intervention based on immersive virtual reality (VR) that simulates an activity of daily living (ADL) on cognitive functions and its impact on depression and the ability to perform such activities in patients with MCI.
METHODS: Thirty-four older adults (men, women) with MCI were randomized to the experimental group (n = 17; 75.41 ± 5.76) or control (n = 17; 77.35 ± 6.75) group. Both groups received motor training, through aerobic, balance and resistance activities in group. Subsequently, the experimental group received cognitive training based on VR, while the control group received traditional cognitive training. Cognitive functions, depression, and the ability to perform activities of daily living (ADLs) were assessed using the Spanish versions of the Montreal Cognitive Assessment (MoCA-S), the Short Geriatric Depression Scale (SGDS-S), and the of Instrumental Activities of Daily Living (IADL-S) before and after 6-week intervention (a total of twelve 40-minutes sessions).
RESULTS: Between groups comparison did not reveal significant differences in either cognitive function or geriatric depression. The intragroup effect of cognitive function and geriatric depression was significant in both groups (p < 0.001), with large effect sizes. There was no statistically significant improvement in any of the groups when evaluating their performance in ADLs (control, p = 0.28; experimental, p = 0.46) as expected. The completion rate in the experimental group was higher (82.35%) compared to the control group (70.59%). Likewise, participants in the experimental group reached a higher level of difficulty in the application and needed less time to complete the task at each level.
CONCLUSIONS: The application of a dual intervention, through motor training prior to a cognitive task based on Immersive VR was shown to be a beneficial non-pharmacological strategy to improve cognitive functions and reduce depression in patients with MCI. Similarly, the control group benefited from such dual intervention with statistically significant improvements.
