If a patient presents with inferior GH instability, which two tests should a therapist consider performing?

The Feagin Test and the Sulcus Sign are both specifically designed to assess glenohumeral joint instability, particularly in cases of inferior instability.

The Feagin Test helps evaluate if there is inferior glenohumeral instability by placing pressure on the humeral head while the patient is in a standing or seated position. A positive test indicates a drop in the humeral head and suggests that the inferior glenohumeral ligament may be compromised.

The Sulcus Sign also assesses for inferior instability by pulling downward on the arm while the patient is seated. A noticeable indentation or "sulcus" beneath the acromion can indicate inferior laxity in the glenohumeral joint capsules and ligaments.

Together, these tests provide crucial information regarding the integrity and stability of the glenohumeral joint, making them the most appropriate choices for assessing inferior GH instability.
