Does this patient with shoulder pain have rotator cuff disease?
For patients with shoulder pain, the physician could perform a single pain provocation test (painful arc test), 3 strength tests (internal rotation lag test, external rotation lag test, and drop arm test), and 1 composite test (external rotation resistance test). There are many possible combinations of findings with these 5 tests, so most of the combinations have not been studied for their independence, making the selection of an appropriate likelihood ratio difficult > from Hermans et al.; JAMA. 310 (2013) 837-847.
