Abstract

BACKGROUND

The number of older adults with dementia is expected to increase. Dementia is not only characterized by a decline in cognition, also other functions, for example, physical functioning change. A possible means to decrease the decline in these functions, or even improve them, could be increasing the amount of physical activity. A feasible way hereto may be activation of the mirror neuron system through action observation. This method has already been shown beneficial for the performance of actions in, for example, stroke patients. The primary aim of this study is to examine the effect of observing videos of walking people on physical activity and physical performance, in older adults with dementia. Secondary, effects on cognition and quality of life related factors will be examined.

METHODS/DESIGN: A cluster randomized controlled trial is being performed, in which videos are shown to older adults with dementia (also additional eligibility criteria apply) in shared living rooms of residential care facilities. Due to the study design, living rooms instead of individual participants are randomly assigned to the experimental (videos of walking people) or control (videos of nature) condition, by means of drawing pieces of paper. The intervention has a duration of three months, and takes place on weekdays, during the day. There are four measurement occasions, in which physical activity, physical functioning, activities of daily living, cognition, the rest-activity rhythm, quality of life, and depression are assessed. Tests for participants are administered by a test administrator who is blind to the group the participant is in.

DISCUSSION

This study examines the effect of the observation of walking people on multiple daily life functions and quality of life related factors in older adults with dementia. A strength of this study is that the intervention does not require much time and attention from caregivers or researchers. A challenge of the study is therefore to get to know for how long residents watch the videos. However, the design implies a high feasibility of the study, as well as a high applicability of the intervention into daily care.

摘要

背景

老年痴呆症患者的数量预计将会增加。痴呆症不仅表现为认知能力下降，还包括其他功能，例如身体功能的变化。减少这些功能衰退甚至改善它们的一种可能方法是增加身体活动量。实现这一目标的一种可行方法可能是通过动作观察激活镜像神经元系统。这种方法已被证明对例如中风患者的动作表现有益。本研究的主要目的是检验观察行走人群的视频对老年痴呆症患者身体活动和身体表现的影响。其次，将研究其对认知和生活质量相关因素的影响。

方法/设计：正在进行一项整群随机对照试验，在养老院的共享客厅向患有痴呆症的老年人（还有其他入选标准）播放视频。由于研究设计，通过抽签的方式将客厅而非个体参与者随机分配到实验组（行走人群的视频）或对照组（自然视频）。干预为期三个月，在工作日白天进行。有四次测量时机，在此期间评估身体活动、身体功能、日常生活活动、认知、静息-活动节律、生活质量和抑郁情况。对参与者的测试由对参与者所在组不知情的测试管理员进行。
