概括
老年人的脚下感觉恶化与正常行走和应对某些平衡挑战时更大的步行不稳定性有关. 改善足部感觉可能有助于预防这种人群的跌倒.
科学领域:
- 老年学是一门学科.
- 生物力学 生物力学
- 神经学 神经学
背景情况:
- 晚年与脚下感觉减弱有关,由感觉值升高表明.
- 据假设,减少脚部感觉会增加老年人跌倒的风险,特别是在走路时.
- 脚下感觉和在乱下走路平衡之间的关系仍然没有得到充分的研究.
研究的目的:
- 量化脚部感觉与步行不稳定之间的关联.
- 评估脚部感觉如何与各种行走扰乱期间的平衡控制有关.
主要方法:
- 在28名老年人中,使用Semmes-Weinstein单丝测量了足部感觉.
- 稳定性边缘 (MoS) 和全身角动量 (WBAM) 在习惯性行走过程中得到量化.
- 分析了对光流,横向腰部拉动和跑步机滑动干扰的反应.
主要成果:
- 较高的单纤维值 (更糟糕的感觉) 与较大的MoS和在习惯性行走期间增加的WBAM相关.
- 更糟糕的足部感觉与MoS的较大下降和WBAM在侧腰拉动扰动期间的增加有关.

01:19The Effect of Aging on Tissues
3.6K
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...

Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor.
