How many degrees can the scapula rotate?
50° to 60°
The scapula on the thorax contributes to elevation (flexion and abduction) of the humerus by upwardly rotating the glenoid fossa 50° to 60° from its resting position.
What is internal rotation of the scapula?
Definitions of Scapular Movements. ◆ Internal rotation: – rotation of the scapula (about a vertical. axis at the acromioclavicular joint) » lateral border of the scapula moves.
What is scapular tipping?
A condition in which the inferior angle of the scapula is prominent, usually the result of faulty posture and a tight pectoralis minor muscle. Tipping is a normal motion when a person reaches with the hand behind the back.
What is the ratio of glenohumeral motion to scapular rotation?
a 2:1 ratio
If the scapulothoracic rhythm is properly coordinated, an individual will have approximately 120 degrees of glenohumeral abduction and 60 degrees of upward rotation of the scapula. There is about a 2:1 ratio of movement in the glenohumeral joint to that of the scapulothoracic articulation.
How much does the scapula move?
Scapulohumeral rhythm is the rhythm in which our scapula moves, in relation with the humerus in the glenohumeral joint as a means for shoulder mobility. The standard ratio is often recognized as 2:1. This means for every 2 degrees the humerus moves, the scapula moves 1 degree.
What is the normal degree of hip flexion?

|Knee flexion||141.9 (140.9 – 142.9)||137.7 (136.5 – 138.9)|
|Knee extension||1.6 (1.1 – 2.1)||1.0 (0.6 – 1.4)|
|Ankle dorsiflexion||13.8 (12.9 – 14.7)||12.7 (11.6 – 13.8)|
Do Shoulderblades move?
When the shoulder blade moves towards the spine. Inward Rotation: When the bottom corner edge of the shoulder blade rotates down and in towards to the spine. Outward Rotation: When the bottom corner edge of the shoulder blade rotates up and away from the spine.
