STAND IN FRONT OF PATIENT, TEST BOTH ARMS AT SAME TIME

• 1. Active
• 2. Passive
  • if Active is restricted
  • stop immediately if painful
• 3. Power (MRC grading)

Lateral Elevation | Abduction 0–160/180°

• Note glenohumeral & scapulothoracic
  • Put hand on shoulder to stabilise shoulder
• Note ROM
• Active then Passive
  • Active
    • elevate both arms in coronal plane
    • comment on
      • 1. Initiation
      • 2. scapulohumeral rhythm
        • Scapula moving too early & creating a shrugging effect (R/C path, Glenohumeral Osteoarthritis)
        • 60° Scapulothoracic, 120° GHJ
        • non-linear relationship between GHJ and scapular contribution
      • 3. painful arc syndrome (impinged or torn RC)
        • Pain in midrange of abduction suggests minor rotator cuff tear or supraspinatus tendonitis
          • Ask if any pain during this movement
          • Can’t watch face from behind!
      • 4. Pain at the end of abduction (AC arthritis)
      • 5. range (160°-180°)
  • Passive (if active not restricted due to pain)
    • if not full, passive to 180° comment on
      • active vs passive
    • Warn patient about movement
    • Hold patients shoulder & elbow
      • If passive is more than active
        • ? R/C pathology
  • Observe arm lowering comment on
    • arc of pain
    • drop arm

Forward Flexion 160-180°

• Active
  • both arms raised forward
  • comment on
    • NEER’s Impingement
    • range
    • ability (trick movements)
    • check contour of axilla
• Pathology
  • ↓ in arthritis, adhesive capsulitis, R/C tears
  • R/C impingement limits abduction more than forward flexion
  • ↑ passive over active – R/C pathology, weakness of scapular stabilizers

Adduction (Horizontal flexion)

• Adduction by cross body/cross chest adduction
  • Forward flex shoulder to 90deg
  • Try to touch opposite shoulder
  • Measure the distance from the cubital fossa to opposite acromion
  • Normal: cup hand over other shoulder at least, often more
  • ↓ in ACJ pathology
• Option
  • Adduction by swinging extended arm across body (30deg)

External Rotation 45 – 90°

• Active with shoulder adducted
  • elbows flexed to 90° & arms by side
  • start with arms forward
  • rotate arms outwards (90°)

Passive

• if not full, passive

Option

• Active with shoulder abducted 90°
  • do not do this if patient had pain on abduction!
  • arms abducted to 90° & elbows flexed 90°
  • external rotation (90°)
  • internal rotation (90°)
    • usually 20° greater in dominant arm
    • Watch for compensatory arching of back
    • In this position, it may be falsely limited in patients at risk of involuntary subluxation, dislocation
    • ↓ ER – massive R/C tear
      • in massive R/C tears, passive motion with ↑ ROM but patients arm will drift back on letting go

FROM BEHIND PATIENT

Internal Rotation

• Apley Scratch Test (T7 for women, T9 for men)
  • Reach behind your back & run your thumbs over the middle of your spine
• Mark with your index finger & compare to contralateral side
  • superior angle of scapula (T2)
  • blade of scapula (T4)
  • inferior angle of scapula (T7)
  • Iliac crests – L4-5 interspace
  • Abdomen, greater trochanter, PSIS, sacrum
  • This movement also requires extension but is a very functional measurement
  • 2 levels higher in non-dominant hand
  • IR is the first motion lost in adhesive capsulitis (last to come back)
• Options
  • IR in 90° abduction (30-45deg)
  • You can also test by asking patient to
    • Hands behind head: ER in abduction
    • Hands up back IR in adduction

• If the patients arm falls back to 0° of ER, than +ve test
• 100% sensitivity & 100% specificity for irreparable degeneration of the infraspinatus

3. Hornblower’s sign

• Power of external rotation in 90° of abduction in the scapular plane
• Examiner places the patients elbow at 90 deg flexion with maximal ER
• Examiner’s other hand is used to judge external rotation force

• Described in Gerber’s 1996 article
• Patients with R/C pathology usually cannot do lift off test because of ROM
• Resisted Internal Rotation with hand on belly
• Must keep elbow forward

I’m going to hold onto your elbow

Could you now try to “Press your wrist into your belly”

• Negative
  • Elbow forward
  • Pt uses subscap to internally rotate arm to press belly
• Positive
  • Pt compensates for lack of subscapularis
    • Extending shoulder

2. Gerber subscapularis lift off test

• Christian Gerber in JBJS(B) 1991
• “Pathological lift off test – patient is unable to lift the dorsum of his hand off his back”
  • Put dorsum of patients hand on buttock then lift it off buttock & let go
  • Gerber’s test is normal if patient can hold hand off buttock
  • Pt must have full IR & not be limited by pain to use this test
• other feature that Gerber described was ↑ passive ER with indistinct endpoint

AC Joint

• 1. Localized crepitus over AC joint
• 2. Passive Cross-chest adduction
• 3. AC injection with LA

2. O’Brien Test

• Stephen O’Brien Am J Sports Medicine 1998
• Step 1
  • Elbow straight
  • FF shoulder to 90°
  • 15° towards midline
  • IR arm until thumb points downward
  • Apply downward force whilst patient resists it
  • Note presence & location of pain
• Step 2
  • Palm now faces forward
  • Apply downward force whilst patient resists it
• Positive if
  • Pain only during step 1
  • Pain at top of shoulder is AC joint
  • Pain deep in shoulder is injury to glenoid labrum

Biceps Tendon

Tendinitis

• Localised tenderness
• Speed Test
• Yergason’s test

Speed Test

• FF 90 deg, elbow extended, palms pointing towards the ceiling
• Push down on wrists & patient resists
• Positive if patient complains of pain
• Assess pain or popping at bicipital groove (long head of biceps)

Yergason’s Test

• Arm by the side, elbow flexed 90 deg, pronate forearm
• Shake patient’s hand
• Ask patient to try to flex & supinate forearm
• Positive if patient complains of pain in anterior aspect of shoulder

Stability

Biceps Instability Test

• Associated with R/C tear
• Stop sign position: abduction 90°, elbow flexed, ER shoulder
• Feel for bicipital groove
• IR shoulder
  • palpable or audible click & pain as biceps tendon reduces & then subluxates passing over the lesser tuberosity

Stability Testing

• Anterior Instability
  • Sitting (on edge of couch)
    • Quantitative laxity >Stability Testing>
    • AP drawer
    • Load & shift
  • Provocative
    • Jerk
• Lying
  • Provocative tests
    • Apprehension
    • Relocation
    • Release

Quantitative Tests of Laxity

• Test for amount of laxity

1. Sulcus Sign

• Pt sitting
• This is testing for inferior instability
• needs to be compared to the opposite side
  • in front of patient
  • hands in lap
  • pull down on elbow, other hand gripping acromion to stabilize it
  • one at a time
• look for sulcus between lateral edge of acromion & humeral head

Grade	Distance
1	1 cm
2	1-2 cm
3	> 2 cm

• Suggestive of multidirectional instability
• Performing this test with arm adducted stresses the superior glenohumeral ligament & rotator interval
• Performing this test with the arm abducted 90° stresses the IGHL.
• If there is inferior translation without symptoms the patient has inferior laxity; if there are symptoms the patient has inferior instability

2. Drawer Test – anterior & posterior

• Always examine other shoulder first
• Stabilise scapula with other hand (grip Acromion)
• Grasp proximal humerus with thumb & index finger
• Push anteriorly & posteriorly
• Normal
  • 25% anteriorly
  • 50% posteriorly
• But compare with other side

3. Cofield’s Stability Tests (glenohumeral ligament)

• Glenohumeral ligament is tightened with progressive ER
• Anterior & posterior draw performed with varying degrees ER
• Supine

4. Load & Shift Test

• Similar to Drawer test but shoulder is mildly abducted
  • Pt is at edge of table so that shoulder hangs off it & the table then acts to counteract applied forces
  • Tuck the pt’s hand into your arm pit, thus freeing both hands to manipulate the shoulder
  • Vary the amounts of abduction to find the most laxity
    • A compressive force is delivered to the humeral head to reduce it into the glenoid. The arm is positioned in 20° of abduction, 20° of forward flexion & neutral rotation. Anterior & posterior forces are then placed on the proximal humerus & direction & degree of translation are determined.

Grade	Description
1	head translation up to the glenoid rim that is greater than the other side
2	head translates over the glenoid rim but spontaneously reduces when the force is removed
3	humeral head translation over the glenoid rim which remains locked when the force is removed

Provocative Tests

Posterior Instability – Patient SittingProvocative Tests

ock-heading" id="1-jerk-test-posterior-stress-test">1. Jerk Test / Posterior stress test

• Arm is at 90° forward flexion & flexed at the elbow to 90°
• A pressure is applied posteriorly to translate the shoulder back, then the arm is brought around to abduction & the shoulder relocated
• scapula is stabilized with the other hand during this manouver.
• Positive if apprehension or Jerk felt
  • patient experiences pain +/- apprehension
  • unlike anterior test patient has +ve test if pain only
  • should reproduce the patients symptoms

2. Passive Circumduction Adduction Manoeuvre

• Standing position
• Stand behind patient
• Hand to stabilize shoulder & feel for subluxation
• Elbow extended, move arm to extended & slightly abducted postion
• Then passively move patient’s arm in circle movement moving backwards & upwards
• At the top of circle, move arm to front of patient into flexed & adducted position
• Posterior dislocation occurs when shoulder is forward flexed & adducted

Posterior Instability – Patient Sitting

1. Apprehension Test

• Ask patient to relax
• Take it slow & ask patient to say when it hurts etc
• Abduct shoulder to 90°
• Elbow flexed to 90°
• Examiner then ER arm
• Positive if
  • Pt reacts by expressing concern or anxiety
  • look for apprehension (pain not reliable indicator)

2. Relocation (Jobe Relocation Test)

• Push posteriorly on the anterior aspect of proximal humerus
  • This should relieve the patients symptoms

3. Release

• By releasing or easing the posteriorly directed pressure the patient’s apprehension should return

Other options

4. Crank Test

• Similar to apprehension test, but in upright position
• Examiner’s thumb pushes on posterior shoulder to apply anterior leverage
• index & middle fingers are positioned on anterior shoulder to prevent against sudden dislocation

LIGAMENTOUS LAXITY (Wynne-Davies Criteria)

1. Thumb touching forearm on flexing wrist
2. Fingers parallel to forear>LIGAMENTOUS LAXITY (Wynne-Davies Criteria)t 180°
3. Knees extend past 180°
4. Foot dorsiflex past 45°
