概括
在健康的年轻成年人中,生物阻抗测量显示肢体之间的差异很小,这表明没有受伤的膝盖可以作为监测受伤膝盖胀和愈合的基线.
科学领域:
- 生物医学工程 生物医学工程
- 运动医学 运动医学
- 整形外科 整形外科 整形外科
背景情况:
- 膝盖受伤会导致胀,监测其解决方案是评估愈合和恢复运动的关键.
- 生物阻抗提供了一种客观的方法来测量胀,可能有助于膝盖受伤后的临床决策.
- 这项研究确定了年轻,活跃个体的基线生物阻抗变性,以了解肢体之间的差异.
研究的目的:
- 测量年轻,活跃个体的膝盖生物阻抗.
- 定义基线变化和影响肢体间生物阻抗差异的因素.
- 评估生物阻抗对监测膝盖胀和愈合的潜力.
主要方法:
- 使用脚/脚和大腿传感器测量生物阻抗,类似于全膝关节关节整形术后的协议.
- 验证了方法的可重复性;然后,在78名健康受试者 (平均年龄21岁) 中测量了生物阻抗.
- 一般化的多变量线性回归分析了年龄,BMI,大腿周长和膝盖功能 (KOOS-JR) 对阻抗测量和四肢差异的影响.
主要成果:
- 生物阻抗测量显示了高的重复性 (COV 1.5%,ICC 97.9%).
- 女人显示出明显更高的主导四肢阻抗和更大的四肢之间的阻抗差异比男性.
- 受试者的性别和BMI显著影响了生物阻抗;年龄和膝盖功能得分没有. 肢体之间的差异平均很小 (<5%).
结论:
- 健康膝盖之间的生物阻抗测量是相似的,验证了使用未受伤的膝盖作为监测受伤的对侧膝盖愈合的基准.
- 进一步的研究应该探索膝盖功能得分和生物阻抗之间的关系.
- 研究性别和解剖学变异对生物阻抗测量的影响是有必要的.

The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
Changes in the Appendicular Skeleton with Age
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...
