Posterior Impingement Sign Test

The Posterior Impingement Sign Test is a diagnostic tool used by healthcare professionals to identify both internal and external rotation and posterior shoulder pain and impingement. It involves specific maneuvers to provoke symptoms and assess shoulder function.

The test is performed with the patient lying down, shoulder, and elbow at 90 degrees. The examiner moves the arm into maximal external rotation, internal rotation, and abduction, checking for pain or discomfort that indicates impingement.

This test may be beneficial for patients who often experience shoulder pain or stiffness, especially those involved in activities requiring repetitive overhead movements, to diagnose potential internal shoulder impingement.
