Shoulder Flashcards
Movements of the scapula?
Upward rotation
- occurs with abduction or flexion of the shoulder
Downward rotation
- occurs with shoulder extension and adduction
Scapular abduction
Protraction
Serratus anterior
Pectoralis minor
Vertebral border of the scapula moves laterally
The shoulder joint adducts horizontally
Scapular adduction
Retraction
Middle and lower trapezius
Rhomboid major and minor
The vertebral border of the scapula moves medially
The shoulder joint abducts horizontally
Scapular elevation
Upper trapezius
Levator scapulae
Shoulder shrugs
The shoulder
Glenohumeral joint
3 planes of movement:
- Flex/ext: 0-180, 0-50; no hyperextension
- Abd/add: 0-180
- Int/ext rotation: 0-120
Shoulder flexion
Expected ROM: 180º
Muscles: anterior deltoid, coracobrachialis (less than 90º), supraspinatus
Test position: supine or seated to prevent hyperextension of lumbar
- arm pronated
Goniometer
Fulcrum: slightly below the acromion, through head of humerus
Stationary arm: mid-axillary line of trunk
Moveable arm: longitudinal midline of humerus
Things to watch for:
- Hyperextension of lumbar
- Elevation of scapula
- Don’t be fooled by elbow
Shoulder extension
Expected ROM: 50º
Muscles: latissimus dorsi, teres major, posterior deltoid, coracobrachialis (above 90º)
Test position: prone to prevent hyperextension of lumbar
- arm pronated
Goniometer
Fulcrum: slightly below the acromion, through head of humerus
Stationary arm: mid-axillary line of trunk
Moveable arm: longitudinal midline of humerus
Things to watch for:
- Hyperextension of lumbar
- Elevation of scapula
- Don’t be fooled by elbow
Shoulder abduction and adduction
Expected AROM: 0-180º
- adduction is the return to 0º
Position: supine, prone, or seated
- shoulder should be fully externally rotated
Goniometer
fulcrum: lateral aspect of the chest, slightly below acromion
Stationary arm: parallel to sternum, lateral aspect of trunk
Moveable arm: midline of humerus
Possible substitutions
Spinal flexion toward contralateral side
Elevation of scapula
Flexion of humerus
Shoulder horizontal adduction
Occurs in the transverse plane. Is a combination of motions between scapula, clavicle, and humerus.
Expected ROM: 0-120º (depends on start position)
Position: supine
Goniometer
Fulcrum: superior aspect of shoulder over acromion
Stationary arm: along superior aspect of scapula
Moveable arm: along midshaft of humerus
Horizontal abduction
Expected AROM: 0-120º
Position: supine or seated
Goniometer
Fulcrum: superior aspect of shoulder over acromion
Stationary arm: along superior aspect of scapula
Moveable arm: along midshaft of humerus
Substitutions:
- trunk rotation
Internal (medial) rotation
Expected ROM: 65º-90º
Position: supine
- elbow bent to 90º
- shoulder is brought to 90º of abduction; if not possible, measure from point able and document
Goniometer
Fulcrum: through humeral shaft, the tip of the elbow
Stationary arm: perpendicular to the floor or lined up with the trunk
Moveable arm: along the ulnar shaft
External (lateral) rotation
Expected ROM: 90º
Position: supine
- elbow bent to 90º
- shoulder is brought to 90º of abduction; if not possible, measure from point able and document
Goniometer
Fulcrum: through humeral shaft, the tip of the elbow
Stationary arm: perpendicular to the floor or lined up with the trunk
Moveable arm: along the ulnar shaft
Potential substitution patterns:
- trunk flex/ext
- elbow extension
- wrist flex/ext
Scapular elevation MMT
Muscles: upper trapezius and levator scapulae
Palpation: upper trapezius, lateral to cervical spinous process
Position: seated (AG), supine or prone (GM)
- have patient pull shoulders towards ears
- resistance: medial to acromion process in a downward motion
To minimize the affect of the trapezius and focus on the levator, have the patient put their hand behind their back.
Scapular elevation muscles
Upper trapezius
O: superior nuchal line and ligamentum nuchea
I: lateral third of clavicle and acromion process
N: spinal accessory nerve
Levator scapulae
O: transverse process of upper four cervical vertebra
I: medial border of scapula
N: dorsal scapular nerve
Scapular adduction MMT
Muscles: middle trapezius
Palpation: between the vertebral border of scapula and spinous process of cervical and upper thoracic vertebra
Position: prone (AG), sitting (GM)
AG
- Patient is prone with elbows flexed over the edge of the table, instruct the patient to lift elbows
- Apply pressure to mid-medial scapula and push out
GM
- in sitting with arm supported
- ask patient to bring shoulder blades together
Scapular adduction muscle
Middle trapezius
O: spinous process of T1-T5
I: superior border of scapular spine
N: spinal accessory nerve
Scapular depression and adduction
Muscles: lower trapezius
Palpation: between medial scapular spine and thoracic vertebra
Position: prone (AG and GM)
- AG: shoulder is abducted to 130 degrees, ask client to lift arm off table, apply resistance to the inferior angle of scapula, up and out
- GM: same position, but you might have to support the arm
Scapular depression and adduction muscles
Lower trapezius
O: spinous process of T6-T12
I: scapular spine
N: spinal accessory nerve
