Muscles of the Shoulder

Muscles of the Shoulder

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.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...

Avoidance Learning and Learned Helplessness

Avoidance Learning and Learned Helplessness

Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

Associative Learning

Associative Learning

Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Purposive Learning

Purposive Learning

E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a...

Observational Learning

Observational Learning

Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Learning Disabilities

Learning Disabilities

Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
Dyslexia
Dyslexia is a...

Area of Science:

Orthopedic surgery
Medical education technology

Background:

Video-based learning enhances medical skill acquisition.
YouTube is a popular resource for medical students and trainees.
A systematic review of YouTube video reliability for medical education is needed.

Purpose of the Study:

To evaluate YouTube videos as educational tools for four key shoulder physical examinations.
To analyze the reliability and usefulness of these videos.

Main Methods:

Searched YouTube for 'Neer test,' 'Hawkins test,' 'empty can test,' and 'drop arm test' videos.
Two physicians assessed video characteristics and usefulness (very useful, somewhat useful, not useful, misleading).
Correlated video usefulness with upload source and viewer engagement metrics (views, likes).

Main Results:

200 eligible videos were analyzed; 51 were 'very useful' and 32 were 'misleading'.
Video usefulness strongly correlated with upload source (physician-uploaded videos were more useful) and viewer preferences (likes, views).
Videos uploaded by physicians showed significantly higher usefulness and viewer engagement than those by individuals.

Conclusions:

YouTube videos can serve as valuable learning resources for shoulder physical examinations.
Filtering videos based on upload source (e.g., physicians) and viewer engagement is crucial for effective use.
