This study aimed to identify the magnitude and type of balance and mobility impairments in people with Alzheimer disease by comparing their performance with that of older people without cognitive impairment.
Twenty-five community-dwelling people with mild to moderate Alzheimer disease and a comparison group of 25 cognitively intact age- and sex-matched people completed a comprehensive balance and mobility assessment. This included computerized posturography measures of static and dynamic balance under various conditions, clinical balance, and mobility measures, and measures of falls and falls risk.
The level of falls risk was higher in people with Alzheimer disease. Standing balance in people with Alzheimer disease was significantly impaired across a range of static and dynamic balance conditions. Activity level, gait, and mobility measures were also impaired, particularly turning and dual tasks.
The findings of the study highlight the value of including balance screening as a routine component of early dementia assessment. This would allow for the early detection of balance dysfunction and the introduction of balance retraining before impairments progress to more advanced levels.
本研究旨在通过比较阿尔茨海默病患者与无认知障碍的老年人的表现，确定阿尔茨海默病患者平衡和移动障碍的严重程度和类型。
25 名居住在社区的轻度至中度阿尔茨海默病患者和 25 名年龄和性别匹配、认知功能正常的对照组参与者完成了一项全面的平衡和移动评估。这包括在各种条件下使用计算机进行静态和动态平衡的姿势描记术测量、临床平衡和移动测量，以及跌倒和跌倒风险测量。
阿尔茨海默病患者的跌倒风险水平更高。阿尔茨海默病患者的站立平衡在各种静态和动态平衡条件下均显著受损。活动水平、步态和移动能力也受损，特别是转身和双重任务。
研究结果强调了将平衡筛查作为早期痴呆评估常规组成部分的重要性。这将允许在平衡功能障碍进展到更高级别之前，早期发现并进行平衡训练。
