Neumann described 6 Kinematic Principles of Full Shoulder Abduction to help guide your answer. Please indicate which of the following three are correct? 1) If a person had normal scapulohumeral rhythm, and 180 degrees of abduction, this person would have about 120 degrees of that motion coming from the scapulothoracic joint. 2) The upward rotation of the scapula during full shoulder abduction is the result of a simultaneous elevation at the sternoclavicular joint combined with downward rotation of the acromioclavicular joint. 3) The clavicle protracts at the sternoclavicular joint during shoulder abduction. 4) The scapula posteriorly tilts and externally rotates during shoulder abduction 5) The clavicle posteriorly rotates around its own axis during shoulder abduction. 6) The Glenohumeral joint externally rotates during shoulder abduction
