Indications:

Reverse Impingement test is a shoulder examination used to determine the presence of shoulder impingement.

Reverse Impingement test for shoulder

Patient supine with shoulder abducted ~95° & arm externally rotated, examiner pushes the head of the humerus inferiorly while applying a mild external rotatory force on the arm.

Interpretation:

Positive Pain decrease or disappearance → Mechanical Impingement under the acromion.

Clinical notes:

This maneuver decreases the compressive force between the supraspinatus tendon/greater tuberosity to the humerus & the acromion.
Due to the similarity of the anterior apprehension test, extreme caution should be taken when dealing with unstable shoulders.
