Test Item Cluster:
When this test is combined as a cluster with the Hawkins-Kennedy Impingement Sign and the Painful Arc sign, and all three tests report a positive, then the positive likelihood ratio is 10.56 and if all three tests are negative, the negative likelihood ratio is 0.17. If two of the three tests are positive, then the positive likelihood ratio is 5.03.[1]
Test Item Cluster:
This test may be combined as a cluster with the Drop-Arm Sign and the Painful Arc Sign to test for the presence of a full-thickness rotator cuff tear. If all three tests report positive results, then the positive likelihood ratio is 15.6 and if all three tests are negative, the negative likelihood ratio is 0.16. If all three tests are positive and the patient is older than 60 years, the positive likelihood ratio is 28.0. If two of three tests are positive, the positive likelihood ratio is 3.60.[2]
