A patient presents with inferior GH instability. What are two tests that the therapist should consider performing?

In the context of inferior glenohumeral (GH) instability, the Feagin Test and the Sulcus Sign are both relevant assessments. The Feagin Test specifically evaluates the integrity of the inferior capsule and can indicate the presence of inferior instability by testing the resistance of the glenohumeral joint to inferior translation. This test is particularly focused on the inferior direction, aligning well with the patient's condition.

The Sulcus Sign involves pulling downward on the arm while the patient is seated, which can create a visible sulcus or groove below the acromion if there is inferior shoulder laxity or instability. This test is effective in assessing the amount of inferior translation and may indicate underlying capsular laxity.

Both tests focus on the stability of the glenohumeral joint, making them particularly suited for a patient presenting with inferior GH instability. Other tests listed, such as the Drop-Arm Test, Apprehension Crank Test, Hawkins-Kennedy Test, Neer Test, and Lift-Off Sign, are more focused on other conditions related to shoulder pathology, such as rotator cuff tears, impingement syndromes, or anterior instability.
