概括
年龄化的肌肉组成和姿势稳定性在年轻人中是相关的,但不是老年人. 这种脱表明,老年人对跌倒风险有独立的贡献,强调需要不同的评估策略.
科学领域:
- 老年学是一门学科.
- 生物医学工程 生物医学工程
- 运动学 运动学
背景情况:
- 衰老与肌肉构成和姿势稳定性下降有关,这两者都是跌倒的风险因素.
- 与年龄相关的肌肉变化和姿势控制之间的关系仍未得到充分研究.
- 了解这种相互作用对于制定有针对性的防摔策略至关重要.
研究的目的:
- 为了研究与年龄相关的肌肉组成和姿势稳定性之间的关系.
- 为了比较年轻人和老年人的肌肉特性和姿势控制.
- 确定肌肉组成是否预测不同年龄组的姿势稳定性.
主要方法:
- 超声波成像量化的肌肉回声强度和质地在Vastus Lateralis和双臂.
- 使用双脚姿势期间的压力变化中心来评估姿势稳定性.
- 灰色级别的同时发生矩阵分析被用于纹理量化.
- 规范性相关性分析检查了肌肉和姿势措施之间的关系.
主要成果:
- 年轻的成年人表现出比老年人更低的回声强度和更高的肌肉均性.
- 肌肉回声强度,厚度和纹理参数有效地区分了年龄组.
- 只有在年轻成年人中才发现肌肉构成和姿势摆动之间的显著相关性.
- 在老年人中,肌肉组成和姿势稳定性之间没有显著的关系.
结论:
- 在老年人中,姿势稳定性和肌肉组成是分离的,这表明独立的贡献跌倒的风险.
- 基于纹理的超声波参数为评估肌肉质量提供了对回声强度的可靠替代方案.
- 未来的研究应该在评估老年人跌倒风险时单独考虑这些因素.

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

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...
