Shoulder/Arm Flashcards
Levator Scapula attachments
TPs C1-4 and medial, superior angle of scapula.
What movements does Levator Scapula control
Cspine - extension, side bending
Shoulder - elevation
What nerve supplies Levator Scapula
Cervical nerve (C3-C4) and dorsal scapular nerve (C5).
Levator Scapula
Supine - Pt rotates head slightly towards side your testing. Resist side bending, back of hand above ear, other hand resists shoulder elevation.
Infraspinatus attachments
Infraspinatus fossa of scapula and greater tubercle of humerus.
What movements does Infraspinatus control
Shoulder - External rotation
What nerve supplies Infraspinatus
Suprascapular nerve - C5-C6
Infraspinatus
Supine - Elbow bent 90deg. Humerus abducted 90deg. Resist lateral rotation while stabilising opposite side of elbow.
Supraspinatus attachments
Supraspinous fossa of scapula and greater tubercle of humerus.
What movements does Supraspinatus control
Shoulder - 0-15 abduction
and assists deltoids in 0-90deg abduction
What nerve supplies Supraspinatus
Suprascapular nerve - C5-C6
Supraspinatus
Supine - Humerus abducted 10-15deg and shifted slightly off the table. Resist abduction superior to the wrist.
Prone - arm at the side, elbow locked and fully on couch. Resist first 15deg of abduction.
Subscapularis attachments
Subscapular fossa of scapula and lesser tubercle of humerus.
What movements does the Subscapularis control
Shoulder - internal rotation
What nerve supplies the Subscapularis
Upper and lower subscapular nerves - C5,C6
Subscapularis
Humerus is abducted between 45-90deg. Resist medial rotation, while stabilising opposite side of elbow.
Biceps, Long Head attachments
Supraglenoid tubercle of scapula and tuberosity of radius.
What movements does Biceps, Long Head control
Elbow - flexion
What nerve supplies Biceps, Long Head
Musculocutaneous nerve - C5,C7
Biceps, Long Head
Supine - Humerus abducted 45deg. Resist elbow flexion.
Prone - Elbow bent 90deg. Grasp forearm superior to the elbow. Resist movement of the hand to the shoulder.
Coracobrachialis attachments
Coracoid process and middle third of humeral shaft
Coracobrachialis movements
Flexion and adduction of humerus
Coracobrachialis nerve supply
Musculocutaneous nerve (C5- C7)
Coracobrachialis
Humerus abducted slightly, elbow bent 90.
Place hand on arm above elbow while grasping Pts hand resist flexion of the shoulder.
Pronator Teres attachments
Medial epicondyle of humerus and middle of lateral shaft of the radius. (Anterior forearm)
What movements does Pronator Teres control
Elbow - pronator teres, flexion
What nerve supplies Pronator Teres
Median nerve, C6-C7
Pronator Teres
Supine/sitting - Elbow bent, grasp thumb with one hand, back of other hand against Pts back of hand. Resist pronation with both hands.
Supinator attachments
Lateral epicondyle of humerus and lateral surface of proximal third of the radius.
What movements does Supinator control
Elbow - supination
What nerve supplies Supinator
Radial nerve, C7-C8
Supinator
Supine/sitting - Pts elbow bent. Place one of your hands behind thumb and index finger and other hand on hypothenar eminence. Resist supination with both hands.
Jeep resistance relatively light - if too strong biceps will dominate movement.
Anterior deltoid attachments
Lateral third of clavicle and deltoid tuberosity
Anterior deltoid movements
Flexion, adduction and medial rotation
Anterior deltoid nerve supply
Axillary nerve C5-6
Anterior deltoid
Resist forward flexion from supine
Clients elbow is bent 90 and resist downward movement
Medial deltoid attachments
Lateral acromion and deltoid tuberosity
Medial deltoid movements
Abduction to 90deg
Medial deltoid nerve supply
Axillary nerve C5-6
Medial deltoid
Humerus abducted 90, elbow bent 90, resist further abduction above elbow.
Posterior deltoid attachments
Lateral acromion and deltoid tuberosity
Posterior deltoid movements
Extension, abduction and lateral rotation
Posterior deltoid nerve supply
Axillary nerve C5-6
Posterior deltoid
Resist extension
Tricep long head attachments
Infraglenoid tubercle on scapula to olecranon
Tricep long head movements
Extension of shoulder and elbow
Tricep long head nerve supple
Radial nerve C7-8
Tricep long head
Elbow locked, arm by Pts side resist behind wrist.
Triceps medial and lateral attachments
Posterior humerus and olecranon
Triceps medial and lateral movements
Extension of the elbow
Triceps medial and lateral nerve supply
Radial nerve C7-8
Triceps medial and lateral
Humerus slightly abducted and elbow 90, resist extension with hand superior to wrist.
