Changes in the Appendicular Skeleton with Age

3.3K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

科学领域:

  • 生物力学 生物力学
  • 老年学是一门学科.
  • 运动学 运动学

背景情况:

  • 了解与年龄相关的步态变化对于移动性和跌倒预防至关重要.
  • 身体活跃的老年人可能与他们久坐不动的同行保持不同的步态特征.

研究的目的:

  • 为了比较年轻成年人和身体活跃的老年人之间的步态参数.
  • 调查年龄和特定步态指标之间的关系.

主要方法:

  • 一项涉及81名参与者的横向病例控制研究 (18-45岁的年轻人,60岁以上的活跃老年人).
  • 使用PodoSmart Insole系统进行步行分析,以收集时空和运动数据.
  • 统计分析包括用于组比较的t测试和与年龄相关的趋势的Pearson相关性.

主要成果:

  • 在两个年龄组之间,在步伐长度,节奏,接触时间,摇摆时间和支阶段持续时间方面观察到显著差异.
  • 年龄与节奏,接触时间,摇摆时间和支阶段持续时间有中度至强度的负相关性,这表明随着年龄的增加,参数变差.
  • 在每个年龄组中,在步态变量中注意到性别差异.

结论:

  • 年轻的成年人和活跃的老年人在步态参数中表现出明显的差异.
  • 虽然步态随着年龄的增长而变化,但老年人的身体活动水平可能会影响这些模式,这需要进一步调查.
