概括
弓形支鞋在老年人中改善了单腿平衡时间. 然而,它也增加了与赤脚条件相比,在行走时的姿势摇摆和能量成本.
科学领域:
- 生物力学 生物力学
- 老年学是指老年学的学科.
- 整形外科 整形外科 整形外科
背景情况:
- 步行和姿势控制对于老年人群的移动性和跌倒预防至关重要.
- 研究了包括支在内的鞋类干预措施,以提高稳定性和步行经济性.
研究的目的:
- 调查支弓的鞋类对中老年和老年人的步态和姿势控制的影响.
- 为了比较支持性鞋类,非支持性鞋类和赤脚条件的影响.
主要方法:
- 45名参与者接受了评估,包括单腿姿势测试 (SLST),姿势摇摆测试 (SPST) 和使用无线传感器进行步行评估 (WA).
- 走路的能量成本 (CWT) 用跑步机测量.
- 在三个条件下收集数据:支形鞋 (SF),非支形鞋 (NF) 和赤脚 (BF).
主要成果:
- 与赤脚 (BF) 相比,支持性鞋类 (SF) 显著增加了单脚姿势时间 (p=0.036).
- 然而,SF也导致在姿势摇摆测试 (p<0.046) 中压力中心 (COP) 面积和速度显著增加 (p<0.046).
- 与BF相比,步行的能量成本与SF相比显著更高 (p<0.033).
结论:
- 弓形支鞋可以提高老年人的单腿站立平衡.
- 尽管改善了平衡,但门支可能会对姿势摇摆产生负面影响,并增加步行能量消耗.
- 需要进一步的研究,以优化鞋类设计,在这个人群中实现平衡和高效步行.

01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
01:00Pharmacokinetics 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...
01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...
01:27Pharmacodynamics in Geriatric Patients: Effects of Age
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
01:30Cognitive 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,...
