Purpose[edit | edit source]

This test is used to assess the stability of the Glenohumeral joint.

Technique[1][edit | edit source]

The patient should be seated. The therapist stabilizes the scapula to the thorax with one hand, while the other hand is placed across the posterior GH joint line and humeral head, and the web space across the patient's acromion. The index finger should the over the anterior GH joint line. The clinician should now apply a "load and shift" of the humeral head across the stabilized scapula in an anteromedial direction to assess anterior stability, and in a posterolateral direction to assess posterior instability. Normal motion anteriorly is half of the distance of the humeral head, more movement is considered to be a sign of GH joint laxity.

Evidence[edit | edit source]

Gerber & Ganz report this test to be 100% sensitive for the detection of instability in patients with recurrent dislocation, but not subluxation.[4]


See test diagnostics page for explanation of statistics.
