To test the middle deltoid against gravity for a muscle grade of 4 or 5 for Anterior Deltoid (shoulder flexion) or Middle Deltoid (shoulder abduction) you need to position shoulder at:

90 degrees of shoulder humeral flexion or shoulder humeral abduction

180 degrees of shoulder humeral flexion or shoulder humeral abduction

45 degrees of shoulder humeral flexion or shoulder humeral abduction

120 degrees of shoulder humeral flexion or shoulder humeral abduction

What is shoulder sublaxation?

Shoulder sublaxation is incomplete or partial separation of the GH joint where the head of the humerus has partially slipped out of the glenoid fossa without tearing or rupturing of soft tissue structures

Shoulder sublaxation is complete separation of the GH joint where the head of the humerus is torn from the glenoid fossa

Shoulder sublaxation is incomplete or partial separation of the GH joint where the head of the humerus has partially slipped out of the glenoid fossa without tearing or rupturing of soft tissue structures

Shoulder sublaxation occurs when the AC joint is dislocated.

Shoulder sublaxation occurs when the SC joint is dislocated and/or the clavicle is fractured

All of the following muuscles are involved in the motion of shoulder (humeral) flexion, except:

Coracobrachialis and Subscapularis (assister)

Scapulohumeral Rhythm is:

Coordinated movement of the GH & SC & AC joints that generally occurs in a 2:1 ratio of GH motion to SC & AC joint motion. GH motion occurs at the beginning and end of the shoulder flex/ext & abd/add. Scapular movement occurs between 80 to 140 degrees of flex/abd.

Coordinated movement of the GH & SC joints where 5 degrees of GH motion follows 2 degrees of SC motion. GH motion occurs with the first 90 degrees of shoulder flex/ext. and abd/add.

Coordinated movement of the AC & SC joints where 2 degrees of AC motion follows 4 degrees of SC motion throughout ROM

Coordinated movement of the GH & SC & AC joints that generally occurs in a 2:1 ratio of GH motion to SC & AC joint motion. GH motion occurs at the beginning and end of the shoulder flex/ext & abd/add. Scapular movement occurs between 80 to 140 degrees of flex/abd.

Coordinated movement of the scapulothoracic motion and AC & SC joints that occurs in a 2:1 ratio. Scapulothoracic motion occurs within 40 to 120 degrees of shoulder flex/ext & abd/add.

Which of the following activities requires full shoulder external rotation?

Brushing/combing your hair on the back of your head

Which one of the following activities would require the action of shoulder depression?

Pushing down on arm rests of a chair in order to stand up

Reaching an object on top of the refrigerator

Pushing down on arm rests of a chair in order to stand up

Putting a hat on top of your head

What is the closed packed postion for the GH joint and what is the joint end feel for this position?

Closed packed position is maximal shoulder abduction and external rotation; End feel is firm

Closed packed position is maximal internal rotation and adduction; end feel is soft

Closed packed position is maximal shoulder extension; End feel is firm

Closed packed position is maximal shoulder abduction and external rotation; End feel is firm

Closed packed position is maximal horizontal adduction and internal rotation; end feel is soft

If the GH joint were immobilized by osteoarthritis (frozen shoulder) and only 20 degrees is available at the GH joint, what range of shoulder flexion and abduction would be available to the upper extermity?

20 degrees of GH motion, plus 30 degrees from SC joint (movement from AC joint unavailable) = approx. 50 degrees available for flex/abd

Only 20 degrees of shoulder flexion and abduction would be available because no motion is available at AC & SC joints

20 degrees of GH motion, plus 30 degrees from SC joint (movement from AC joint unavailable) = approx. 50 degrees available for flex/abd

20 degrees of GH motion, plus 30 degrees from AC joint (movement from SC joint unavailable) = approx. 50 degrees available for flex/abd

20 degrees of GH motion, 120 degrees from ST motion = approx. 140 degrees available for shoulder flex/abd

A substitution or trick movement for scapular elevation can be which one of the following motions?

Bringing head down to shoulder by tipping head to side

Lateral trunk extension toward weak side

Bringing head down to shoulder by tipping head to side

If the clavicle were unable to rotate on its axis because of injury at the SC joint, what functional movement issues would be seen at the shoulder girdle complex?

Only approximately 90 to 110 degrees of shoulder flex/abd would be possible

No movement issues would be seen at the shoulder girdle complex

Movement of the shoulder would be limited to 30 degrees of shoulder flex/abd

Only approximately 90 to 110 degrees of shoulder flex/abd would be possible

Movement of the shoulder would be limited to internal rotation

A substitution or trick movement for shoulder abduction to 90 degrees can be any of the following motions except:

Bringing head down to shoulder by tipping head to side

Contralateral or Ispilateral trunk side flexion

Bringing head down to shoulder by tipping head to side

What happens if you excessively load the hanging (dependent) limb, especially is situations where muscle function has been impacted by stroke, or other brain injury?

shoulder sublaxation would occur

Shoulder disclocation would occur

Which of the following activities requires full shoulder internal rotation?

Brushing/combing your hair on the back of your head

Which of the following activities requires full shoulder flexion/adduction?

Brushing/combing your hair on the back of your head

Which one of the following activities would require the action of shoulder elevation?

Reaching an object on top of the refrigerator

Pushing down on arm rests of a chair in order to stand up

Putting a hat on top of your head

The shoulder complex is an intricately designed combination of three joints that link the upper extremity to the thorax – it is composed of the clavicle, scapula and humerus. What can you tell us about the complex?
