Purpose
[edit | edit source]
Codman's test is typically used in the assessment of a suspected rotator cuff tear.
Technique
[edit | edit source]
The therapist passively raises the patient's arm to 90 degrees of abduction. The patient then lowers the arm back to neutral with the palm down. If the patient's arm drops suddenly or experiences pain, then the test is considered positive.
Evidence[edit | edit source]
Test Item Cluster:
This test may be combined as a cluster with the Infraspinatus Test 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.[1]
