Q

Briefly describe what subacromial pain syndrome is, its symptoms, its cause, and aggravations

A

Non-traumatic, usually unilateral, shoulder problems that cause pain, localized around the acromion.
Often present with:
- painful arc of pain
- pain after activity and early AM
- pain during ER and elevation
Pain is usually associated with a change in load to the tendon and often worsens during overhead activities and overuse

Q

Briefly describe what rotator cuff tendinopathy is, its symptoms, its cause, and aggravations

A

Indicates a problem with your shoulder muscles. It can be caused by an overload of the four muscles located in that region, or an inflammation of one of the tendons.
Often present with:
- painful arc of pain
- pain after activity and early AM
- pain during ER and elevation
Pain is usually associated with a change in load to the tendon and often worsens during overhead activities and overuse

Q

What would be included in a subjective history of the shoulder joint?

A
  1. Onset
    - insidious/ trauma/ timescale
  2. Pain behaviours
    - location, severity, 24-hour pattern, aggs and eases
  3. Special questions
    - locking, red flags, previous dislocations
  4. PMH and general health
    - THREADS

Q

How do glenohumeral joint related pains differ from acromioclavicular joint and sternoclavicular joint pain?

A

Glenohumeral joint pains = commonly felt over the anterior deltoid, often extending into the region of the distal deltoid and biceps
Acromioclavicular joint and sternoclavicular joint pain = often felt locally around the joint

Q

Give some red flags for the shoulder joint

A
  • history of cancer
  • sudden weight loss
  • fracture
  • dislocation
  • history of heart attack
  • sweating and chest pain when shoulder pain occurs
  • jaw, mouth or teeth pain when shoulder hurts

Q

What would you look for in both the informal and formal observation?

A
Informal
 - observe how they use their arms, facial expressions and quality of movement
Formal 
 - observe in sitting and standing
 - skin colour changes
 - inspect muscle bulk for symmetry
 - head of humerus
 - elbow length - compare epicondyles

Q

What part of the body must we clear first and how?

A

Clear the thoracic spine

  • the patient sits with arms across the chest
  • perform thoracic flexion, extension. side flexion, rotation and apply overpressure
  • no pain reproduced = no pain in the thoracic spine

Q

Name and describe 2 tests for rotator cuff related shoulder pain

A
  1. Neer test
    - begin in sitting position. stabilize scapula with one hand, internally rotate arm (pronation), maximum flexion with overpressure
    - pain reproduction is a positive test
  2. Hawkins Kennedy test
    - begin in sitting position, 90degrees shoulder flexion, 90degrees elbow flexion, stabilize the scapula and hold elbow. Apply internal rotation (hand brought down)
    - pain reproduction is a positive test

Q

Name and describe 2 tests for RC tears

A
  1. IR lag sign
    - hand of painful shoulder on the lumbar region, lift hand off back passively to full IR and ask the patient to maintain position.
    - positive test = hand moves towards the back, subscapularis tear
  2. Drop arm test
    - 90degrees arm abduction, ask the patient to lower smoothly
    - positive test = sudden drop or weakness during lowering, supraspinatus tear

Q

Name the origin, insertion, and action of the subscapularis

Q

Name the origin, insertion, and action of the supraspinatus

A

Origin: supraspinous fossa of scapula
Insertion: superior part of the greater tubercle of the humerus
Action: initiates abduction of the arm

Q

Name the origin, insertion, and action of the infraspinatus

A

Origin: infraspinous fossa of scapula
Insertion: inferior part of the greater tubercle of the humerus
Action: rotates arm laterally

17
Q

Name the origin, insertion, and action of the teres minor

A

Origin: posterior surface of the scapula, adjacent to its lateral border
Insertion: greater tubercle of the humerus, inferior to infraspinatous
Action: rotates arm laterally

18
Q

What exercises would you recommend?

A

Isometric external rotation - strengthens muscle without moving it and risking pain/ further injury (can be done at work
Rows - sitting position with knees slightly bent, wrap a resistance band around feet and hold each end. Pull the band back, like rowing
Bear hugs - stretches rotator cuff muscles. Place a resistance band around back, holding each end, with thumbs pointed up. Bring your arms out and forward, to give a big hug

19
Q

What test can be used for subacromial impingement?

A

The Painful Arc Test is considered positive for supraspinatus impingement if the patient reports pain between 60 degrees and 120 degrees of abduction. Pain should reduce after 120 degrees of abduction. If the patient instead reports pain at the end of abduction, acromioclavicular joint dysfunction is indicated.
