Summary
Post-stroke upper extremity spasticity often develops within the first month, but can emerge later. Early and ongoing assessment is crucial for managing this common condition in stroke survivors.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Clinical Neuroscience
Background:
- Upper extremity spasticity is a common complication following stroke.
- The timing and regional patterns of spasticity development are not fully understood.
- Early identification and management are key to improving functional outcomes.
Purpose of the Study:
- To investigate the time course of upper extremity spasticity development after stroke.
- To identify regional differences in spasticity onset within the upper limb.
- To explore factors associated with spasticity development and severity.
Main Methods:
- Retrospective observational study involving 861 patients with post-stroke upper limb spasticity.
- Data collected from a nationwide multicenter study in South Korea.
- Spasticity defined by a modified Ashworth Scale score ≥1.
Main Results:
- Median time to spasticity development was 34 days post-stroke.
- Approximately 50% of cases developed within the first month.
- 12% developed between 2-3 months, and 13% after 3 months.
- Elbow, wrist, and fingers were most frequently affected.
- Younger survivors experienced more severe spasticity, which increased over time.
Conclusions:
- Post-stroke upper extremity spasticity can manifest at various times, including months after the initial event.
- Spasticity assessment should continue into the chronic phase of recovery.
- Understanding the temporal and regional aspects aids in targeted rehabilitation strategies.

01:17Veins 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...

01:12Arteries 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...

01:15Bones 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...

01:09Bones 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...

01:19Bones 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...

01:27Regulation of Stroke Volume
4.8K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
