概括

与认知健康的老年人 (OACH) 相比,认知障碍 (OACI) 的老年人在跌倒后表现出更大的平衡障碍. 这凸显了OACI需要有针对性的防摔策略,以减轻反复发生的跌倒风险.

科学领域:

老年学是指老年学的学科.
神经学神经学
生物医学工程生物医学工程

背景情况:

与跌倒相关的后果和平衡/走路障碍在认知障碍 (OACI) 的老年人中比认知健康的老年人 (OACH) 更明显.
关于OACH和OACI之间的跌倒后平衡和步态差异的证据有限,尽管它们对反复跌倒风险的意义重大.

研究的目的:

在OACH和OACI中调查严重跌倒后,步行和站立平衡的早期损伤.
通过集成到功能性性能测试中的惯性测量单元 (IMU) 来评估差异.

主要方法:

69名OACH (平均年龄72.0±8.2岁) 和76名OACI (平均年龄78.7±8.1岁) 的分层样本,基于蒙特利尔认知评估得分 (损伤≤24分).
在严重跌倒的急诊室访问后4周内,使用三个IMU测量了站立平衡和步行参数.
使用ANCOVA,调整以年龄为准,用于统计分析.

主要成果:

与OACH相比,OACI在平衡任务中表现出明显更大的影响力.
在各种姿势条件 (平行,双重,眼睛开/闭,平衡) 中观察到的平均速度和路径长度的差异.
两组之间没有发现 significant 的步态行为差异.

结论:

与OACH相比,OACI在下跌后表现出较差的平衡控制,这表明后续下跌的风险较高.
有效的二次跌倒预防策略至关重要,特别是对于OACI.
使用IMU早期发现平衡障碍可以为有针对性的干预提供信息.

Cognitive Development During Adulthood

Cognitive Development During Adulthood

Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...
