在老年人中,平衡信心与不同户外环境中的行走参数有关
Gerontology
|December 9, 2025
概括
具有更高平衡信心的老年人表现出改善的步态参数,包括更快的步行速度和更一致的步伐,特别是在不同的斜坡上. 这凸显了平衡信心在评估老年人的步态时的重要性.
科学领域:
- 老年学是一门学科.
- 生物力学 生物力学
- 运动学 运动学
背景情况:
- 感知平衡信心对于老年人的步行稳定性至关重要,特别是在不同的环境中.
- 了解平衡信心和特定步行参数之间的关系对于预防跌倒的策略至关重要.
研究的目的:
- 在不同环境中调查老年人平衡信心和户外步行参数之间的关联.
- 为了确定高与低平衡信心的老年人之间步行参数的差异.
主要方法:
- 一项涉及39名老年人 (平均年龄76岁) 的横截面研究使用IMU在水平,上坡和下坡步行时评估了步行参数 (节奏,步伐持续时间).
- 资产负债表的信心用特定活动的资产负债表信心 (ABC) 尺度来衡量.
- 共变量包括体力活动,自我评估的健康状况,跌倒史,以及SPPB和TUG等测试中的表现.
主要成果:
- 平衡信心与平面和上坡地形上的节奏正相关,与平面和上坡地形上的节奏变化和下坡和步伐持续时间的节奏变化负相关.
- 高平衡信心 (ABC ≥80) 的老年人表现出更高的节奏 (7-8%),更短的步伐时间上坡/下坡,更快的平行步行速度 (0.14 m/s),以及与低信心 (ABC <80) 的人相比,降低了上坡步行变化.
- 根据平衡信心水平,观察到行走参数的显著差异.
结论:
- 平衡自信是老年人步行模式的重要差异化因素,特别是在具有挑战性的地形上.
- 将自我评价的平衡信心与上坡行走测试相结合,可能会为老年人群的个人步态变化提供有价值的见解.

Homeostatic Imbalance
Homeostasis is the maintenance of a stable internal environment within the body, which is crucial for the proper functioning of cells, tissues, organs, and organ systems. The body has various control mechanisms that work together to regulate various physiological parameters such as temperature, blood pressure, pH balance, and fluid balance, to name a few. These control mechanisms are based on feedback loops that can be either positive or negative.
However, sometimes these feedback loops fail,...

Drug Dosing: Geriatric Patients
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are not...
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,...
