概括
与异常运动相比,观察正常的上肢运动可以提高脑镜神经元系统活动和肌肉参与度. 这表明在康复中专注于正确的运动模式是恢复的关键.
科学领域:
- 神经科学是一个神经科学.
- 康复医学 康复医学 康复医学
- 发动机控制器的控制器
背景情况:
- 卒中通常会损害上肢功能,影响运动控制和神经元活动.
- 镜像神经元系统 (MNS) 在运动学习和模仿中起着至关重要的作用.
- 了解观察不同运动模式如何影响神经和肌肉反应对于中风康复至关重要.
研究的目的:
- 为了研究在大脑皮层和上肢肌肉活动的差异,在模仿达到任务后观察中风后个体的正常与异常运动模式.
- 评估观察到的运动质量对镜像神经元系统 (MNS) 活动和肌参与的影响.
主要方法:
- 一项涉及17名单边中风患者的横截面研究.
- 脑电图 (EEG) 用于测量肌节律 (MNS活动) 和脑电图 (EMG) 用于测量上肢肌肉活动 (百分比最大自愿收缩).
- 参与者观察预先记录的正常和异常的上肢达到任务,然后模仿正常的运动;在行动观察和模仿 (AOI) 期间收集的数据.
主要成果:
- 在对C3和C4电极的异常运动 (p <0.01) 相比,EEG分析显示在观察正常运动时显著增加了律抑制 (表明增强了MNS活动).
- 电磁磁图显示,在模仿正常运动的观察后,脊上肌肉活动显著增加 (p = 0.027).
结论:
- 观察正常的上肢运动会导致MNS激活更高,肌肉参与更大,而不是观察中风幸存者的异常运动.
- 治疗师指导的行动观察训练侧重于正常运动模式,同时避免异常模型,被推作为中风康复的成本效益高,基于神经生理学的辅助.

Veins of Upper Limbs
4.0K
The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...

Arteries of the Upper Limbs
2.2K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Bones of the Upper Limb: Ulna
4.3K
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...

Bones of the Upper Limb: Radius
4.6K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Bones of the Upper Limb: Humerus
7.0K
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...

Naturalistic Observations
17.0K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
