Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...

概括

身体的姿势,无论是坐着还是站着,都不会显著影响快速准确的手动. 研究人员在姿势之间没有发现上肢表现的差异,即使在操纵兴奋水平时也是如此.

科学领域:

  • 电机控制和生物力学
  • 人类因素和人体工程学

背景情况:

  • 姿势配置对于准备运动至关重要.
  • 不同的身体姿势对运动性能的影响仍然不清楚.

研究的目的:

  • 研究身体姿势 (坐着与站着) 如何影响快速准确的平面点对点的手动.
  • 为了确定兴奋操纵是否影响不同姿势中的运动性能.

主要方法:

  • 23名健康的成年人执行了一项Go/No-go任务,涉及重复的点对点的手动.
  • 通过电刺激的虚假威胁来操纵兴奋水平.
  • 记录的数据包括上肢动力学,压力位移中心和四种条件 (坐着/站着与/或没有兴奋操纵) 的电磁皮肤反应.

主要成果:

  • 兴奋水平在具有和没有兴奋操纵的条件之间有显著差异.
  • 在坐姿和站姿之间没有观察到兴奋水平的显著差异.
  • 与坐着相比,压力中心位移的开始在站立的情况下更早.
  • 在姿势之间或由于兴奋操纵而导致的上肢性能没有发现显著差异.

结论:

  • 在经过测试的实验条件下,身体姿势 (坐着或站着) 似乎不会影响上肢运动性能.
  • 在这项研究中,兴奋操纵没有影响上肢表现.
  • 未来的研究可以探索其他类型的运动或人口.
