概括
脑卒中后的患者表现出改变的地面反应力变化 (GRF变化),特别是在侧减少了前后GRF变化. 这种可变性差异在摔倒者中更加明显,这表明适应式步态控制机制可以防止摔倒.
科学领域:
- 生物力学 生物力学
- 神经学 神经学
- 康复科学 康复科学 康复科学
背景情况:
- 脑卒中后的行走障碍增加了跌倒的风险.
- 地面反应力变化 (GRF变化) 在中风后步态稳定性中的特定作用尚未完全理解.
研究的目的:
- 为了比较中风后患者和年龄相匹配的对照人群在行走时的GRF变异性.
- 为了确定中风后落者和非落者之间GRF变异性的差异.
主要方法:
- 19名中风后患者和19名年龄匹配的对照参与了这项研究.
- 在行走过程中使用鞋子传感器测量了地面反应力变化.
- 进行了统计分析,包括对步行速度,性别和形进行调整.
主要成果:
- 与对照组相比,中风后的患者在91-100%的姿势阶段表现出明显较低的前后 (AP) GRF变异性.
- 在中风组内的落者在多个姿势阶段 (41-50%,51-60%,61-70%,和91-100%) 中表现出较低的AP GRF变异性.
- 敏感性分析表明,在调整性别和形后,没有显著的群体间差异.
结论:
- 在侧减少AP GRF变异性可能表明在中风后的患者中,步态控制的适应机制存在.
- 这些发现表明,改变的GRF可变性模式与中风幸存者的跌倒风险有关.
- 对这些适应机制的进一步研究可以为预防跌倒的策略提供信息.

Rolling Resistance
When a solid cylinder rolls steadily on a rigid surface, the normal force applied by the surface on the cylinder is perpendicular to the tangent at the contact point. However, since no materials are entirely rigid, the surface's reaction to the cylinder involves a range of normal pressures.
For instance, imagine a hard cylinder rolling on a comparatively soft surface. The cylinder's weight compresses the surface beneath it. As the cylinder moves, the material in front of it slows down due to...

Acute Respiratory Failure-IV
Respiratory failure can manifest suddenly or gradually, characterized by a rapid decline in PaO2 and a rapid rise in PaCO2. This situation indicates a severe respiratory problem that may quickly become a life-threatening emergency. One of the early signs of hypoxemic Acute Respiratory Failure (ARF) is a change in mental status due to the brain's sensitivity to oxygen levels and changes in acid-base balance. Symptoms such as restlessness, confusion, and agitation suggest inadequate oxygen...
