4.1 → BASIC SCAPULAR MOVEMENTS
DEPRESSION
Commonly described as translatory motions in which the scapula moves downward (caudally) along the rib cage from its resting position. (Oppo- site to elevation). The scapula is de- pressed by simultaneous contraction of the pectoralis minor, lower fibers of trapezius, and latissimus dorsi.
UPWARD ROTATION
The scapula upwardly rotates when you reach the arm up overhead. During this motion, the inferior angle of the scapula rotates up (superiorly) and to the side (laterally).
ELEVATION
Commonly described as translatory motions in which the scapula moves upward (cephalad) along the rib cage from its resting position. The scapula is elevated, as in shrugging, by simultaneous contraction of the levator scapulae and upper fibers of the trapezius.
PROTRACTION (also known as antepulsion or abduction) During protraction, the scapula move away from the spine and toward the front of the body. Movement where the scapula moves laterally away from the spinal column.
RETRACTION (also known as retropulsion or adduction)
In retraction, the shoulder blade moves closer to the spine. Throwing the shoulder back and pinching the shoulder blades together illustrates adduction of the shoulder girdles.
DOWNWARD ROTATION
Is the opposite of upward rotation. Your scapulae downwardly rotate when you bring your arms down from an overhead position. During this motion, the inferior angle of the scapula moves closer to the spine.
Analytically three types of primary movements of the scapula or shoulder blade can be ditinguished: vertical, lateral, and rotational movements. Internal/external rotation and anterior/posterior tilting are normally considered to be “secondary” scapular motions.
