What are the movements of the scapula?
|
Abduction(Protraction), Adduction(retraction), Downward Rotation, Upward Rotation, Elevation and Depression.
|
|
What is Lateral Tilt? When does it occur?
|
Happens during abduction, scapula rotates about its vertical axis resulting in posterior movement of medial border adn anterior mocement of lateral border
|
|
What is Medial Tilt? When does it occur?
|
During extreme adduction. The scapula rotates about its vertical axis resulting in anterior movement of medial border adn posterior movement of lateral border.
|
|
What is anterior tilt? When does it occur?
|
Rational movement of scapula about frontal axis occuring during glenohumeral hyperextention. Superior border moving anteroinferiorly and inferior angle moving posterosuperiorly.
|
|
What is posterior tilt? When does it occur?
|
Rational movement of scapula about frontal axis occuring during glenohumeral hyperflexion. Superior border moves posteroinferiorly. Inferior border moves anterosuperiorly.
