Summary
This study highlights the importance of scapular stabilizers in shoulder function. Neglecting these muscles can lead to altered biomechanics and decreased shoulder performance, emphasizing the need for targeted rehabilitation.
Area of Science:
- Orthopedics
- Sports Medicine
- Biomechanics
Background:
- Scapular musculature has been historically overlooked in shoulder rehabilitation protocols.
- Recent research has elucidated the critical role of the scapula in upper extremity function.
- Scapular stabilizer weakness can lead to abnormal shoulder biomechanics.
Purpose of the Study:
- To present current knowledge on scapular anatomy and biomechanics.
- To describe the pathomechanics associated with scapular dysfunction.
- To focus on the assessment and retraining of scapular musculature for improved shoulder function.
Main Methods:
- Review of current scientific literature on scapular anatomy, biomechanics, and dysfunction.
- Clinical commentary synthesizing research findings.
- Description of assessment techniques for scapular dysfunction.
- Outline of retraining strategies for scapular musculature.
Main Results:
- Scapular stabilizer weakness can cause abnormal stresses on the shoulder's anterior capsular structures.
- Compromised scapular function increases the likelihood of rotator cuff compression.
- Altered biomechanics due to scapular dysfunction negatively impact overall shoulder complex neuromuscular performance.
Conclusions:
- Effective shoulder rehabilitation requires addressing scapular muscle function.
- Understanding scapular pathomechanics is crucial for accurate diagnosis and treatment.
- Targeted assessment and retraining of the scapular musculature are essential for optimizing shoulder function and preventing injury.

Muscles of the Shoulder
9.4K
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.

Muscles that Move the Arm
5.6K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Muscles that Move the Head
7.6K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Bones of the Upper Limb: Humerus
11.3K
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...

Overview of the Axial Skeleton
11.8K
The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs.

Axial and Appendicular Muscles
3.5K
Skeletal muscles, the key players in our body's movement, can be classified into two groups based on their location and function: axial muscles and appendicular muscles. These classifications reflect the primary roles the muscles play in the body's structure and movement.
Axial Muscles
Axial muscles, situated along the body's midline, are intricately connected to the axial skeleton, which includes the skull, spine, ribs, and sternum. These muscles facilitate facial expressions and...
