Chapter 5: Shoulder Flashcards
What are the active ranges of motions for the shoulder?
- Flexion: 160-180 degrees
- Extension: 50-60 degrees
- Abduction: 170-180 degrees
- Adduction: 50-75 degrees
- External rotation: 80-90 degrees
- Internal rotation: 60-100 degrees
- Cross flexion/cross extension: 130 degrees
What is the glenohumeral painful arc?
About 45-120 degrees of abduction.
What is the acromioclavicular painful arc?
About 170-180 degrees of abduction.
What is scapulohumeral rhythm?
For every 2 degrees of abduction there is 1 degree of scapulothoracic upward rotation.
What is a SICK scapula?
- Scapular malposition
- Inferomedial border prominence
- Coracoid pain and malposition
- dysKinesis of scapular movement
What is scapular dyskinesis?
An alteration in the normal resting or active position of the scapula during shoulder movement.
What is the Apley’s scratch test?
Reach to touch the opposite scapula to test range of motion.
- Over the shoulder tests abduction and external rotation
- Under the shoulder tests addiction and internal rotation
What are force couples?
Groups of counteracting muscles that show obvious action when a movement is loaded or done quickly.
What are the agonists and antagonists of scapular protraction?
Agonists: serratus anterior and pectoralis major and minor.
Antagonists: trapezius and rhomboids
What are the agonists and antagonists of scapular retraction?
Agonists: trapezius and rhomboids
Antagonists: serratus anterior and pectoralis major and minor.
What are the agonists and antagonists of scapular elevation?
Agonists: upper trapezius and levator scapulae
Antagonists: serratus anterior and lower trapezius
What are the agonists and antagonists of scapular depression?
Agonists: serratus anterior and lower trapezius
Antagonists: upper trapezius and levator scapulae
What are the agonists and antagonists of shoulder abduction?
Agonists: deltoid
Antagonists: Supraspinatus
What are the agonists and antagonists of shoulder medial rotation?
Agonists: Subscapularis, pectoralis major, latissimus dorsi, anterior deltoid.
Antagonists: infraspinatus, teres minor, posterior deltoid
What are the agonists and antagonists of shoulder lateral rotation?
Agonists: infraspinatus, teres minor, posterior deltoid
Antagonists: Subscapularis, pectoralis major, latissimus dorsi, anterior deltoid
