POSTERIOR DRAWER TEST

​• ​Test positioning

The client lies supine.

The therapist stands next to the involved shoulder, and holds the client's arm at the elbow, passively abducts the shoulder to 90-degrees, and horizontally flexes the shoulder 20 to 30-degrees.

The client's elbow is flexed in a relaxed position.

The therapist stabilizes the scapula by placing the other hand posterior to the shoulder joint capsule with the thumb over the coracoid process.

​• ​Action

While stabilizing the scapula, the therapist applies downward pressure, pushing the humeral head posteriorly.

The therapist notes any posterior movement of the humeral head.

​• ​Positive finding

Increased posterior instability of the humeral head relative to the scapula/glenoid fossa may be indicative of posterior instability.

The client may exhibit apprehension if the test is positive.

​• Special considerations & comments

​A bilateral comparison should be used for a more accurate assessment.
