Clinical Assessment of the

Shoulder:

What the research says…

Are the Clinical Tests we use Valid?

Sensitivity

“SNOUT”:

➢ A sensitive test can rule out a disease when the result is negative

● A sensitive test = sensitivity > 80%, -LR < 0.20

Specificity

“SPIN”:

➢ A very specific test rules in a disease with a high degree of confidence

● A specific test = specificity > 80%, +LR > 5.0

SLAP lesions● Hegedus et al. (2012):

Passive Distraction and Active Compression = s:70% sp: 90%, +ve LR:7.0, –ve LR: 0.11 (Schlecter, 2009)

Compression-rotation AND Apprehension AND Speed = s: 25%, sp: 92%, +LR: 3.13, -LR: 0.82 for Type 2 only (Oh et al. 2008)

➢ Less optimism for Biceps load II than in Hegedus (2008)

● MRI may be helpful but anatomical variants and Buford complex are normal

● MRI and MR Arthrogram imaging have lower sensitivity than physical examination tests in diagnosing SLAP lesions

➢ in others words, both negative scans and negative cluster testing does NOT rule out a SLAP lesion

Labral Pathology (not exclusive to SLAP)

● Hegedus et al. (2012):

Anterior Slide AND Crank = s: 34%, sp: 91%, +LR: 3.75, -LR: 0.73 (Walsworth et al., 2008)

Apprehension AND Relocation = s: 38%, sp: 93%, +LR: 5.43, -LR: 0.67 (Gaunche & Jones, 2003)

➢ These combinations are good at ruling IN labral pathology but a negative test cannot confidently this rule out…

● Munro (2009):

Kim = s: 80%, sp: 93%, +LR: 12.6, -LR:0.21 (Kim, 2005)

Jerk = s: 73%, sp: 98%, +LR: 34.7, -LR: 0.21 (Kim, 2005)

IRRT (differentiate intra-articular pathology from impingement) = s: 88%, sp: 96%, +LR: 24.7, -LR: 0.12 (Zaslav, 2001)

Rotator Cuff Tears

● Hegedus et al. (2012):

Age ≥ 65 AND Weakness in ER (infraspinatus) AND night pain = s: 49%, sp: 95%, +LR: 9.84, -LR: 0.54 (Litaker, 2000)

Lift off and/or resisted IR (subscapularis) = s: 50%, sp: 95%, +LR: 10.0, -LR: 0.53 (Naredo, 2002)

● Hegedus (2008):

Recommend a combination of bear hug & belly press (s: 40-60%, sp: 88-98%)

● Miller et al. (2008):

ERLS for SSP & ISP, s: 46%, sp: 94%

➢ Tests here appear to be good at ruling in an RCT but a negative test does not mean a RCT/pathology does not exist

AC joint

● No clinical test met the criteria for recommendation by Hegedus (2012) due to high risk of bias from QUADAS 2 assessment

● Two studies looked at clinical tests for the AC joint: Jia et al. (2009) & Goyal et al. (2010)

● Jia et al. (2009) found:● AC resisted extension = s:

72%, sp: 85%, +ve LR:4.8 -LR: 0.33

● Active Compression for AC = s: 41%, sp: 95%, +LR: 8.2, -LR: 0.62

● Cross body for AC joint = s: 77%, sp: 79%, +LR: 3.67, -LR: 0.29

● Goyal et al. (2010) found:● Adductor stress = s: 57%, sp:

96%, +LR:15, -LR: 0.45

And now for the less well defined pathologies….

Subacromial Impingement Syndrome (SIS)● Hegedus et al. (2012):

At least 3 or more positives of the following: Hawkins-Kennedy, Neer, Painful Arch, Empty Can, resisted ER = s: 75%, sp: 74%, +LR: 2.93 and –LR: 0.34 (Michener et al., 2009)

● Park et al. (2005) also recommend this cluster but without the arch sign

● Even with cluster testing adequate levels of sensitivity, specificity, positive & negative LRs are not reached for SIS

● However, consider relevance as would this inform clinical decision making?

● Structural Vs Patterning?

● Consider SSMP (Lewis, 2009) and neuromodulation/patterning re-education

Rotator Cuff Tendinopathy

● Hegedus et al. (2012):

Age > 39, Painful Arch, Self-report of popping or clicking (Chew et al. 2010):

➢ 2 or more positives= s: 75%, sp: 81%, +LR: 3.82 -LR: 0.32

➢ 3 positives = s: 38%, sp: 99%, +LR: 32.20, -LR: 0.63

Lift off and/or Resisted IR = s: 50%, sp: 84%, +LR: 3.13, -LR: 0.60 (Naredo et al, 2002)

However…

● Inadequate sensitivity means a negative test does not mean a tendinopathy doe not exist

● Large cross over with RCT and SIS

● Difficult to evaluate the use of cluster testing in light of Cook and Purdum’s (2009) tendinopathy continuum

Shoulder Instability● Hegedus et al. (2012) Strong

evidence only for Type 1 – 2 anterior instability (Stanmore)

Apprehension and Relocation = s: 81%, sp: 98%, +LR: 39.68, -LR: 0.19 (Farber et al. 2006)

EUA:

● Laxity (Colfield’s technique):● Ant/post drawer signs

● Sulcus sign & Gagey Test for inferior capsule/Rotator interval

For atraumatic instabilities (type III) consider:

● Muscle patterning● Kinetic Chain● Beighton score

➢ Load and shift (no data)

➢ Ant/Post draw (no data)

Adhesive Capsulitis

● Not assessed as current diagnosis is clinical so no criterion standard

● Hegedus et al. (2012):

Shrug Sign appears sensitive for stiffness related disorders (OA and adhesive capsulitis)(Jia et al, 2008)

➢ Essential physical criteria for diagnosis is a marked and equal limitation of External rotation, both passively and actively

● Emig et al. (1995):

MR Arthrogram sensitivity of 70% and a specificity of 95%

➢ Difficult to interpret as etiology and histology is not fully understood

Osteoarthritis

● No data for sensitivity or specificity for clinical shoulder tests

● Based on clinical history, presentation and XRAY

● >50yrs, incidence increase with age

● Insidious and progressively worsening

● Pain: activity dependent, usually intermittent but can be at rest, dull generalised aching, night pain, reduced active and passive ROM all planes, esp. ER, disuse atrophy, possible grinding sensation with joint movements

● XRAYs:● Subchrondral sclerosis +/- cysts ● Osteophytes

● For the knee 24-56% of patients with OA X-ray findings have pain and higher grades of OA are linked with pain ?relevant to shoulder, a none weight bearing joint?

(Parsons et al., 2004)

The best* test combinations and reported values…

● SLAP: Passive Distraction AND Active Compression

● SLAP (T2): Compression-rotation AND Apprehension AND Speed

● Labral Tear: Anterior Slide AND Crank AND/OR Apprehension AND Relocation

● RCT (degen): Age≥65 AND weakness in ER AND night pain

● RCT (none degen): Lift-off and/or Resisted ER

● SIS: Hawkins-Kennedy, Neer, Painful Arch, Empty Can, Resisted ER (3 or more positives)

● RC Tendinopathy (supra): Age > 39, Painful Arch, self-report of popping or clicking

● RC Tendinopathy (subscap): Lift-off and/or Resisted IR

● Anterior Instability (T1): Apprehension AND Relocation*Defined as highest sensitivity, specificity, or both from studies with least bias
