Notes for NPTE
Question | Answer |
---|---|
What is the resting position, close packed position, capsular pattern and non parttern of the glenohumeral joint? | 40-55 abduction, 30horizontal adduction (scapular plane)Full abduction, lateral rotationLateral rotation, abduction, medial rotationexternal rotation, abduction, flexion, internal rotation |
Scapulohumeral rhythm | During 180 of abduction, there is roughly a 2:1 ration of movement of the humerus to the scapula, with 120 of movement occurring at the glenohumeral joint and 60 at the scapulothoracic joint. |
What happen when you have a unstable shouder? | The Scapulohumeral rhythm is commonly altered because of incorrect dynamic functioning of the scapular or humeral stabilizers or both. This may be related to incorrect arthrokinematics at the glenohumeral joint |
What happen when you have a reverse scapulohumeral rhythm? | The scapula moves more than the humerus. The patient appears to “hike” the entire shoulder complex rather than produce a smooth coordinated abduction movement. |
In what way would you mobilize the GH joint to increase ABDUCTION? | INFERIOR CAUDAL |
In what way would you mobilize the GH joint to increase Early flexion (0-45)? | Posterior |
In what way would you mobilize the GH joint to increase internal rotation? | Posterior |
In what way would you mobilize the GH joint to increase Horizontal adduction? | Posterior |
In what way would you mobilize the GH joint to increase extension/lateral rotation? | Anterior |
In what way would you mobilize the GH joint to increase horizontal abduction? | Anterior |
In what way would you mobilize the GH joint to increase late flexion (120-180)? | anterior |
What is the resting position, close packed position, capsular pattern of the acromioclavicular joint? | Arm by side90 abductionPain at extremes of range of motion, especially horizontal adduction and full elevation |
Which branches innervated the acromiclavicular joint? | Branches of the suprascapular and lateral pectoral nerve |
What is the resting position, close packed position, capsular pattern of the esternoclavicular joint? | Arm at sideFull elevation and protractionPain at extremes of range of motion, especially horizontal adduction and full elevation. |
What can you tell about scapulothoracic joint? | Is not a true joint. The muscles acting on the scapula help to control its movements. It does not have a capsular pattern nor a close packed position. |
Which muscles elevate the scapula? (2) | Upper trapeziusLevator scapulae |
Which muscles depress the scapula? (4) | Serratus, pectoralis major & minor, latisimus, trapezius (lower fibers) |
Which muscles protract the scapula? (3) | Serratus anterior, Pec major and minor |

What is the function of the rotator cuff mucles? | They hold the head of the humerus in the glenoid cavity during abduction. |
What happen when the supraspinatus is paralyzed? | Patient experiences no difficulty in raising the arm overhead, but a decrease in strength and endurance resulted. Loss of abd as seen in patients with rupture of the supraspinatus tendon is due to pain. |
What happen when on of the abd muscles is paralyzed? | still can perform an unresisted motion of glenohumeral joint abd with the other, although the strength and functional use in abd is reduced. |
But if both are paralyzed? | Shoulder abd is seriously affected. No true abd is then possible unless the shoulder is fully ext rot. |
What is the fuction of Deltoid? | Pull the humerus up. |
What happen when the deltoid is paralyzed? | Can not perform glenohumeral abd. Instedad, the arm is raised slightly by upward rot. of the scapula nd lateral flex of the trunk |
How patients with isolated deltoid paralysis perfom abduction? | Patients with isolated deltoid paralysis can By ext rot. The glenohumeral joint (to use the biceps) and a slight motion toward flex at around 90 abd. |
What is the function of the trapezius? | Cause upward rotation of the scapula during arm elevation.Support the shoulder girdle and prevent sagging of the shoulder |
What happen when the trapezius is paralyzed? | The support is missing and the shoulder sloper down more than it would normally. The weight of the arm tends to draw the tip of the shoulder down, causing the scapula to rotate downward beyond its normal hanging position. |
How can the shoulder girdle can be elevated even if the trapezius is paralyzed? | The levator scapulare and the rhomboids are caple of doing so without the aid of the upper trapezius. |
What is the function of the serratus anterior? | Cause upward rotation of the scapula during arm elevation? |
What happen when the serratus anterior is paralyzed? | The subject is unable to rise the arm over head as the trapezius cannot bring about enough upward rotation for complete abd. A typical WINGING is seen when it is paralyzed and the scapula fails to side forward on the rib cage. |
What are the indications of loss of scapular control? | scapula protracting along chest wall,under load;early contraction of upper trapezius on abduction,under load; Increased work of rotator cuff and biceps, especially with closed chain activity (reverse oringin-insertion);Altered scapulohumeral rhythm |
Who causes anterior humeral translation? | Weak subscapulares and teres major, tight infraspiatus and teres minor. |
Who causes scapular winging fault on concentric elevation? | Long/weak serratus anterior |
