概括
在无症状个体中,年龄不会影响肩关节位置感 (JPS). 联合位置复制 (JPR) 任务证明了不同年龄组的可靠和可复制的测量.
科学领域:
- 运动学 运动学
- 生物力学 生物力学
- 老年学是指老年学的学科.
背景情况:
- 关节位置感觉 (JPS) 对于运动控制至关重要.
- 了解JPS与年龄相关的变化对于评估肩部功能很重要.
- 之前的研究对年龄和JPS产生了不同的结果.
研究的目的:
- 为了确定年龄是否与无症状个体的肩膀JPS有关.
- 为了评估关节位置复制 (JPR) 任务的可重复性,用于测量肩部JPS.
主要方法:
- 120名无症状的参与者 (18-70岁) 完成了10个JPR任务.
- 任务评估了对反侧和反侧肩的积极和被动JPS准确性.
- 在一个子组中,使用类内相关系数 (ICC) 和标准测量误差 (SEM) 来测量可重复性.
主要成果:
- 年龄和JPR错误之间没有发现显著的关联.
- 反担保 JPR 任务显示出良好的可靠性 (ICC 0.63-0.80).
- 双边的JPR任务具有可变的可靠性 (ICC 0.32-0.79),但所有任务都显示出小的SEM值 (1.1-2.1).
结论:
- 年龄似乎不会对无症状肩膀的JPS产生负面影响.
- 对于评估肩部JPS,JPR任务是可重复的,测量之间有良好的一致性.

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...

The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.
