概括
患有中风 (PwS) 的人适应在不平坦的表面上行走,保持速度和稳定性. 然而,他们表现出有限的脚运动和潜在的疲劳,这表明长期在不平坦的地形上进行导航具有挑战.
科学领域:
- 生物力学 生物力学
- 神经康复疗法 神经康复疗法
- 步态分析 步态分析
背景情况:
- 患有中风 (PwS) 的人在户外行走方面遇到重大挑战,特别是在不平坦的地形上,这阻碍了社会参与.
- 普华永道在跨越不均表面的特定步态适应和局限性仍然不太清楚.
研究的目的:
- 为了比较PWS和健康对照 (HC) 之间的不均表面上的距离上的步态参数变化.
- 为了研究与距离相关的影响步行速度,稳定性,关节动力学和肌肉激活模式在普华永道.
主要方法:
- 19个PWS和19个HC在10米不均的地面上完成了四圈.
- 测量了步行速度,车身加速 (稳定性),关节角度,电肌图 (EMG) 幅度和瞬间平均频率 (IMNF).
- 线性混合模型分析了跨圈的步态参数变化,以确定组对组的相互作用.
主要成果:
- 虽然步行速度和稳定性在各组之间保持着相似的状态,但普华永道在轮回中表现出脚背部屈曲的减少.
- 电磁图谱分析显示,在HC中前幅度增加,但在初始接触期间PwS没有增加.
- 普华永道的IMNF升高表明,关节角度维护的运动单元招募更大,尽管 gluteus medius IMNF下降,表明疲劳.
结论:
- 普华永道在不均的表面上展示了与HC相比的步行速度和稳定性,这表明了一些适应能力.
- 然而,PWS表现出足脚背部屈曲不足和潜在的有限的冲击吸收能力,以及肌肉疲劳的迹象 (例如, gluteus medius IMNF下降).
- 这些发现表明,虽然普华永道可以适应不平坦的地形,但它们的容量是有限的,造成疲劳和功能性能降低的风险.

12.4K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

01:26Profile Leveling and Cross Sections
1.6K
Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes. Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the...

01:16Spinal Cord: Cross-sectional Anatomy
4.4K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

01:29Distance Problem
37
When an object's velocity changes over time, the total distance traveled can be determined by summing small displacement intervals over short increments. This approach approximates the true distance through numerical summation and the use of integral calculus. An estimate of the total displacement can be obtained by measuring velocity at regular intervals and multiplying each value by the corresponding time step.If a runner accelerates over the first three seconds of a race, speed measurements...

02:12Short-distance Transport of Resources
17.5K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

00:54Noncompartmental Analysis: Miscellaneous Pharmacokinetic Parameters
437
The noncompartmental approach is a widely used method in pharmacokinetics to assess drugs' behaviors in the body. It considers several factors, including clearance, bioavailability, and total volume of distribution.
One key aspect of the noncompartmental approach is determining a drug's total clearance. This can be done by dividing the drug dose by the area under the concentration-time curve from zero to infinity. The area under the concentration-time curve represents the drug's...
