概括
免费组织转移 (FTT) 用于转移性足截肢 (TMA) 的肢体救援,与本地片相比,显示出类似的步行参数. 尽管最初的波动较高,但FTT仍然是功能性行走的可行选择.
科学领域:
- 整形外科 整形外科 整形外科
- 生物医学工程 生物医学工程
- 重建性手术是一种重建性手术.
背景情况:
- 自由组织转移 (FTT) 有助于在转移性关节截肢 (TMA) 中挽救四肢.
- FTT的散装可以阻碍鞋履和行走,可能增加的风险.
- 步行分析对于评估TMA后的功能结果至关重要.
研究的目的:
- 以FTT重建的TMA患者的步态模式与本地脚下片进行比较.
- 评估FTT关闭对截肢后行走的生物力学影响.
- 评估FTT作为肢体救援选项,考虑功能结果.
主要方法:
- 十九名TMA患者 (本地 n=14,FTT n=5) 使用可穿戴传感器进行了120秒的步态测试.
- 分析的步行参数包括节奏,速度,步伐长度,四肢支和姿势摇摆 (RMS).
- 单变量和多变量分析比较了组之间的步态参数,控制混因素.
主要成果:
- 没有发现步行速度,节奏,步伐持续时间或中转高度的显著差异.
- 自由组织转移 (FTT) 患者表现出明显更高的根平均平方 (RMS) 摆动 (P=0.041).
- 多变量分析表明,片类型与RMS波动没有独立的关联;在FTT组中观察到更高的BMI和PVD.
结论:
- 时空步态参数在FTT和本地重建之间基本上是可比的.
- 虽然单变量分析显示FTT的波动增加,但在调整后,这不是一个独立的因素.
- 对于TMA来说,FTT似乎是一个有价值的肢体救援选择,对截肢后的行走影响最小.

1.7K
Self-concept is the cognitive and emotional understanding individuals hold about their identity. It evolves through various developmental stages, beginning in infancy and maturing as children grow. This concept influences how individuals perceive their abilities, interact with others, and manage challenges throughout life.
Infancy and Emerging Recognition
During infancy, self-concept is virtually nonexistent. Babies do not distinguish themselves as separate entities and often mistake their...

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

01:15Concept of Pressure at a Point
791
The concept of pressure at a point in a fluid establishes that pressure within a fluid is uniform in all directions at a specific location. This uniformity occurs because fluid molecules exert force evenly across any point due to their random motion and continuous collisions within the fluid. Pressure at a point is determined by the surrounding fluid molecules and is influenced by factors like depth and density, rather than by shape or orientation.
In a fluid at rest, pressure acts equally in...

01:20Understanding Self-Concept
305
The self-concept encompasses individuals' beliefs about themselves, structured through cognitive frameworks known as self-schemas. These schemas function as mental representations of specific traits or behaviors, influencing how self-relevant information is perceived, processed, and remembered. For example, individuals who are schematic for body weight are more likely to interpret routine experiences—such as dining out or shopping—through the lens of that trait. Conversely, those...
