- Gerber Test is used for Subcoracoid Impingement (between the rotator cuff and the coracoid process)
- It is performed in a manner similar to the Hawkins-Kennedy impingement test.
- The arm is forward flexed 90 degrees and adducted 10 to 20 degrees across the body to bring the lesser tuberosity into contact with the coracoid.
- Pain with the maneuver indicates coracoid impingement
