Rationale

Evidence from 8 high quality studies (Liu 2016, Lin 2015, Castoldi 2009, Park 2005, Litaker 2000, Villafane 2015, Holtby 2004, Gillooly 2010) indicate that the following tests are useful to diagnosis full-thickness rotator cuff tear: bear hug test, belly press test, empty can test, external rotator lag sign, external rotation resistance test, full can test, Hawkins test, Hug up test, internal rotation lag sign (IRLS) test, internal rotation resistance test (IRRT) test, Internal rotation resistance test at maximal 90 degrees of abduction and maximal external rotation (IRRTM) test, Jobe Test, Lateral Jobe Test, Lift off test, NEER test, Patte Test, and Yocum test. Generally, these tests are better to diagnose (rule in), than screening (rule out) full thickness rotator cuff tears.

Bear hug test summary

Combined full/partial thickness tears:

One high quality study evaluated the bear hug test to diagnose any rotator cuff tear (Lin 2015). The test results produce a small but sometimes important change in probability of rotator cuff tears (positive LR=3.49, negative LR=0.37).

Belly press test summary

Combined full/partial thickness tears:

One high quality study evaluated the belly press test to diagnose any rotator cuff tear (Lin 2015). The test results produce a small, but sometimes important change in the probability of a tear (positive LR=3.18, negative LR=0.45).

Empty can test summary

However, the test was poor for ruling out partial thickness tears, with a negative test producing a very small decrease in probability of a partial thickness tear(negative LR=0.89).
