phase 1 scapulothoracic rhythm
humerus 30 degrees abduction
scapula = minimal movement
clavicle = 0-5 degrees elevation
phase 2 scapulothoracic rhythm
humerus 40 degrees abduction
scapula = 20 degrees protraction
clavicle = 15 degrees elevation
phase 3 scapulothoracic rhythm
humerus 60 degrees abduction
scapula = 30 degrees rotation
clavicle = 30-50 degrees posterior rotation, 15 upward rotation
