Week 5 - Shoulder Girdle

Question 1

back joint motions

Answer 1

Elevation/depression
protraction/retraction
upward rotation/downward rotation
Scapular tilt

Question 2

Scapulohumeral rhythm

Answer 2

first 30° of shoulder joint movement is all shoulder joint motion

After: every 2° of shoulder flexion/abduction occurring, means scapula must upwardly rotate 1°

2:1 ratio
