Purpose
[edit | edit source]
This test is commonly used to identify possible subacromial impingement syndrome.
Technique
[edit | edit source]
The patient should be instructed to abduct the arm in the scapular plane and then slowly reverse the motion, bring the arm back to neutral position. This test is considered to be positive if the patient experiences pain between 60 and 120 degrees of elevation. [1]
Evidence[edit | edit source]

Test Item Cluster:
When this test is combined as a cluster with the Hawkins-Kennedy Impingement Sign and the Infraspinatus test, 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 .17. If two of the three tests are positive, then the positive likelihood ratio is 5.03.[2]
