Special Note on Shoulder Impingement Syndrome (SIS):
Rotator cuff versus impingement: There is significant overlap between special tests for shoulder impingement syndrome (SIS) and rotator cuff pathology. This makes sense when consideration is given to the contribution of supraspinatus and infraspinatus tendon inflammation to impingement pain. Or, the contribution of rotator cuff pathology to altered recruitment, altered arthokinematics and subacromial compressive forces. Or, consideration given to test positions for the majority of shoulder impingement tests and the considerable amount of lengthening or tension created on rotator cuff muscles, and how that may provoke symptoms in individuals with rotator cuff pathology.
As mentioned in the article Special Tests: Shoulder Impingement Tests, special tests for SIS generally suffer from a lack of specificity. A diagnosis of SIS may be most accurately reached when "anterior shoulder pain is accompanied by negative tests results for other diagnoses". This may imply that SIS tests are not necessary, have little if any predictive value, and may not have any significant influence on practice (28).
