Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

2.5K
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...

Veins of Upper Limbs01:17

Veins of Upper Limbs

4.4K
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...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

7.4K
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

4.6K
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: Radius01:09

Bones of the Upper Limb: Radius

4.9K
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...

Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

496
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Area of Science:

  • Neuroscience
  • Rehabilitation Medicine
  • Exercise Physiology

Background:

  • Aerobic exercise may enhance motor function recovery post-stroke by increasing brain-derived neurotrophic factor (BDNF).
  • BDNF is crucial for neuroplasticity, motor learning, and memory consolidation, potentially augmenting motor training effects.
  • Combining aerobic exercise with task-specific training could offer a synergistic approach to improving upper limb function.

Purpose of the Study:

  • To evaluate the feasibility of a randomized controlled trial (RCT) combining aerobic exercise with task-specific training for stroke survivors.
  • To determine the effect size of this combined intervention on upper limb motor function.
  • To assess recruitment, adherence, retention, acceptability, and adverse events of the combined intervention.

Main Methods:

  • A parallel-group, assessor-blinded RCT design was employed.
  • Participants with upper limb motor dysfunction post-stroke were randomized to task-specific training alone or aerobic exercise followed by task-specific training.
  • Both groups received 60 hours of training over 10 weeks, with outcome measures assessed at baseline, post-intervention, and at 1 and 6 months follow-up.

Main Results:

  • The study focused on feasibility outcomes, including recruitment rates, adherence, and participant acceptability.
  • Primary clinical outcomes, the Action Research Arm Test (ARAT) and Wolf Motor Function Test (WMFT), were used to estimate effect sizes.
  • Data on adverse events were systematically collected to ensure safety.

Conclusions:

  • The combined intervention of aerobic exercise preceding task-specific training appears feasible for individuals post-stroke.
  • Further investigation in a larger Phase 3 RCT is warranted to confirm the efficacy of this combined approach.
  • This intervention holds promise for enhancing upper limb motor recovery and neuroplasticity in stroke rehabilitation.
