Execution
- 1Position the patient sitting or standing and stand behind the patient.
- 2Stabilize the scapula and clavicle with one hand.
- 3Grasp the patient’s elbow with the other hand, keeping the elbow flexed to 90°.
- 4Passively abduct the glenohumeral joint until the scapula and clavicle begin to elevate.
- 5Estimate the glenohumeral abduction angle and compare with the opposite side.
Positive outcome
More than approximately 105° of glenohumeral abduction before scapuloclavicular elevation is positive for inferior glenohumeral ligament laxity and possible inferior labral involvement. Magee cautions that normal passive scapulohumeral rhythm can sometimes show up to 120° of abduction.

CommentGagey’s hyperabduction test is a laxity sign, not a complete diagnosis of symptomatic inferior instability. The 105° threshold should be interpreted with side-to-side comparison and symptom reproduction. Positive results can occur in generalized laxity without pathological instability.
