Context: Shoulder problems constitute a major socioeconomic problem with lifetime prevalence up to 66.7%. To aid the diagnosis more than 184 tests have been described. Although a standardized guideline for a complete shoulder examination is not available, we hypothesize that experienced shoulder surgeons have clear preferences among Shoulder Physical Examination (SPE) tests.
Aim: The aim of this study was to identify the most used SPE tests for 12 selected shoulder pathologies and evaluate the usefulness of these tests in terms of sensitivity and specificity.
Methods and material: In March to May 2014, ten experienced shoulder surgeons were asked to name the SPE tests they would use for 12 pre-selected shoulder pathologies. A literature search on Pubmed.com and on the Cochrane library was conducted to assess the sensitivity and specificity of the most reported SPE tests for each pathology to investigate specificity and sensitivity of the test.
Results: In total 49 SPE tests were named. Nine surgeons reported at least one common SPE test for eight of 12 pathologies. For the following four pathologies; eight surgeons agreed upon one test for one pathology and for the remaining three pathologies six surgeons recommended one common test. The sensitivity and specificities of the 12 chosen tests were allowable.
Conclusion: There was a high degree of agreement on which SPE to use for which shoulder pathology and the specificity and sensitivity of the most reported SPE tests for each pathology were both acceptable. However, there is no clear evidence to support one SPE test over another in the literature.
In the search of a standardized guideline for shoulder examination, we evaluated the clinical practice of shoulder examination among ten experienced shoulder surgeons. The aim was to identify the most used SPE tests and evaluate the usefulness of these tests in terms of sensitivity and specificity and present the preferred SPE used by experienced shoulder surgeons.

|Pathology||ShPE||Description of the ShPE||
|Acromio-clavicular joint arthrosis||Direct palpation||Is performed by digitally palpating the joint and examining for tenderness. Tenderness is considered as a positive test .||
|Subacromial impingement syndrome||Hawkins Kennedy test||Is performed by examining the patient in the sitting or standing position with their arm flexed at 90° and the elbow flexed to 90°, supported by the examiner to ensure maximal relaxation. The arm is then moved into maximal internal rotation. Pain in the sub acromial space denotes a positive sign .||63-95%/25-78% |
|Tear/lesion of the supraspinatus tendon||Jobe’s test||Is performed with the patient standing or seated. The patient holds the arm at 90° of abduction, 30° flexion in the plane of scapula and internal rotated. A positive test consists of pain or weakness on resisting downward pressure on the arms or an inability to perform the test .||
|Tear/lesion of the infraspinatus/ teres minor tendon||The resisted external rotation test||Is performed by passively flexing the elbow to 90°, holding the wrist, and asking the patient to external rotate the shoulder  while the examiner applying internal rotation pressure to provide resistance. A positive test consist of pain or weakness .||46-84%/53-100% |
Tear/lesion of the Subscapularistendon
|The belly press test||
Is performed when the patient presses the abdomen with the hand flat and attempts to keep the arm in maximum internal rotation. The test is considered positive when the elbow drops in a posterior direction, internal rotationis lost, and pressure is exerted by extension of the shoulder and flexion of the wrist .
|Caput longum biceps pathology||The Speeds test||Is performed with the patient standing or seated. The patient hold the arm in 90° flexion, full supination and the elbow extended. The patient then tries to resist a downward force applied by the examiner. The test is considered positive when pain is increased in the shoulder, localized in the bicepital groove .||49-71%/55-85% [5,6]|
|Superior Labrum Anterior-Posterior (SLAP) lesion||O’Brien test||Is performed by flexing the patients arm to 90°, 10° of horizontal adduction, and maximum internal rotation with the elbow in full extension. The examiner applies a downward force at the wrist of the involved arm. The patient is instructed to resist force. If there is pain localized inside the shoulder the test is positive for a SLAP lesion .||47-99%/11-98% |
|Anterior instability||Apprehension test||Is performed by flexing the patients elbow to 90°, then abducting the shoulder to 90° and applying an anterior force to the posterior surface of the shoulder, while externally rotating the shoulder. Apprehension (the sensation of subluxation) or pain indicates a positive test .||50-72%/56-99% |
|Posterior instability||Posterior apprehension test||Is performed by applying posterior force on the anterior surface of an adducted and flexed shoulder. Apprehension by the patient for this movement signifies a positive test .||19%/99% |
|Multi directional instability||The anterior/posterior translocation test||Is performed with the patient in a standing or seated position. The examiner places one hand over the scapula to stabilize the shoulder and uses the other hand to grasp the humeral head. The humerus is then translated anteriorly and posteriorly. An increased translation compared to the opponent shoulder is considered positive .|
|Adhesive capsulitis||Passive Range of Motion (PROM)||Is performed by positioning the patient’s arm in the shoulders principal movements, flexion, extension, abduction, adduction, internal and external rotation. For frozen shoulder the test is considered positive if the passive range of motion is decreased [13-16].|
|Scapula alatae||Wall push up test||Is performed with the patient leaning up against a wall (or down on the floor) with the hands outstretched, facing the wall. The patient is then asked to lean closer towards the wall flexing the elbows and then push the body back, until once again in a standing position. While performing this test the patient’s scapula is observed for movement. If there is rotation or winging of scapula, the test is considered positive .|
Of the more than 184 SPE tests described, 49 were reported by our study population. For eight of 12 pathologies, there was a high degree of accordance as it was possible to identify an SPE test preferred by 9 to 10 of the experts . For the remaining four pathologies, there was a moderate degree of accordance as it was possible to identify an SPE test preferred by 6 to 8 of the experts.
In the examination for acromioclavicular joint arthrosis, there was consensus on the usage of direct palpation as ten out of ten surgeons used this test. It has shown a high sensitivity (96%) but a low specificity (10%) . In other words, a positive test is a poor indicator of presence of the pathology whereas the negative test is a strong indicator of absence of the pathology.
In the examination for subacromial impingement syndrome, there was consensus on the usage of Hawkins-Kennedy test as ten out of ten surgeons used this test. In the literature, the pooled sensitivity was 79% and the specificity 59% . However, in the meta-analysis by Hegedus et al., a Diagnostic Odds Ratio (DOR) around one was reported suggesting a limited usefulness of the test . It has been suggested that the Hawkins-Kennedy test can be used as a screening test of impingement symptoms rather than identifying the pathologic mechanism .
In the examination for tears of supraspinatus tendon, there was consensus on the usage of Jobe’s test as nine out of ten surgeons used it. The sensitivity ranged from 41% to 81% and the specificity ranged from 50% to 98% . A positive test is a rather strong indicator of presence of the pathology and a negative test a rather strong indicator of absence of the pathology .
In the examination for tears of infraspinatus/teres major tendon, consensus was on the resisted external rotation test, which was used by nine out of ten surgeons. The sensitivity ranged from 46% to 84% and the specificity from 53% to 100% . Again, a positive test is a rather strong indicator of presence of the pathology and a negative test a rather strong indicator of absence of the pathology.
In the examination for tears of subscapularis tendon, there was consensus on the Belly press test as nine out of ten surgeons used it. The sensitivity was found to be 40% and the specificity 98% . This means that a positive test is a very strong indicator of presence of the pathology whereas a negative test is a modest indicator of absence of the pathology.
In the examination for pathology of the long head of biceps usage of speeds test was recommended by eight out of ten surgeons. The test has shown a sensitivity ranging from 49-71% and a specificity ranging from 55 to 87% [5,6]. As such, a positive test is a moderate indicator of presence of the pathology and a negative test is a moderate indicator of absence of the pathology. Hegedus et al., recommended the test for examining SLAP lesions rather than pathology of the long head of biceps, whereas Calis et al., recommended the use of Speeds test before use of other SPE tests [6,9].
In the examination for Superior Labrum Anterior and Posterior (SLAP) lesions, there was consensus on the usage of O’Brien test, which was used by nine out of ten surgeons. Sensitivity ranging from 47% to 99% and specificity ranging from 11% to 98% has been found . If ignoring the only study with both high sensitivity and high specificity  a positive test seems to be a moderate indicator of presence of the pathology and a negative test a strong indicator of absence of the pathology.
In the examination for anterior instability ten out of ten surgeons reported the apprehension test. Sensitivity ranging from 50% to 72% and specificity ranging from 56% to 99% has been found . Hegedus et al., found the studies of great quality, but without sufficient power to be incorporated in a meta-analysis .
In the examination for posterior instability, six out of ten surgeons used the posterior apprehension test. A pooled sensitivity of 19% and specificity of 99% have been found . As such, a positive test is a very strong indicator of presence of the pathology whereas the negative test is a poor indicator of absence of the pathology.
In the examination for Multi Direction Instability (MDI), the most frequently used test was anterior posterior-translocation test as seven out of ten surgeons used it. Extra notice should be taken to discrepancy between instability and laxity. Laxity of the shoulder varies between patients and laxity found by an SPE does not automatically imply that the patient has instability .
In the examination for adhesive capsulitis there was consensus on the usage of reduced Passive Range of Motion (PROM) in all directions as ten out of ten surgeons used it. Full passive range of motion in any plane suggests another diagnosis than adhesive capsulitis [13-16]. In other words, this test can be used to exclude the diagnosis rather than confirm it.
In the examination for scapula alatae, six out of ten surgeons reported the wall push up test. For MDI, scapula alatae and adhesive capsulitis we were not able to find any data examining the sensitivity or specificity.
The sensitivity and specificity varied a lot between the 12 chosen SPE tests with sensitivity ranging from 19% to 99% and the specificity from 10% to 100%. Considering this, one could ask if it is reasonable to recommend a standardized guideline based on the chosen tests. A standardized guideline has its clear advantages as it allows for better communication between healthcare professionals and it is a potential aid for inexperienced investigators. On the downside it might limit investigators in pursuing the test that feels best in their hands and it might reduce specificity if people use one instead of numerous tests to investigate for a given pathology . Taken into account that several SPE tests had a high specificity; it might be advantageous to perform a set of two or three SPE tests for each pathology. It does however not seem realistic to expect general practitioners and general physiotherapist to remember between 24 and 36 different tests to do a shoulder examination.
On this basis we find it reasonable to recommend the 12 chosen SPE tests as a minimum repertoire for a good basic shoulder examination or as a general screening for shoulder pathology. Shoulder surgeons, sports physicians, sports physiotherapist and others with a special interest in physical shoulder examination will increase the specificity of their examinations by using additional tests.
However, there is no clear evidence to support one SPE test over another. In order to enhance communication between health care professionals we have highlighted one SPE test for each of the 12 shoulder pathologies. We recommend the use of these 12 chosen SPE tests (Table 2) as a minimum repertoire for a shoulder examination. There is need for better studies examining validity and accuracy for SPE tests and their correlation to treatment outcome.
