The sulcus sign is an examination to determine the extent and/or presence of inferior instability of the glenohumeral joint. This test can be administered with the patient either seated or standing with his arm relaxed at her side. The examiner palpates the shoulder by placing her thumb and fingers on the anterior and posterior aspects of the humeral head. The examiner grasps the patient's elbow with her other hand and applies a downward distraction force. A positive test will result in a sulcus being formed between the acromion and the humeral head as the humeral head moves inferiorly while the force is being applied.

Shoulder - Empty Can Test
The empty can test is used to assess for the presence of injury/pathology to the supraspinatus. This test is also known as the supraspinatus strength test. The patient is either seated or standing with his arms in a position of scapation (approximately 30-degrees of horizontal adduction with the shoulders abducted to 90-degrees). The patient attempts to resist downward overpressure being applied by the examiner. A positive result occurs when the patient is unable to resist the force.
Shoulder - Apprehension Test
The shoulder Apprehension test is also known as the Fowler test or the Jobe relocation test. The examination is used to assess for shoulder instability. This examination is best partnered with the shoulder relocation test. The apprehension test (AKA crank test) is used to assess for an anterior shoulder dislocation. The patient lies on the table supine with the shoulder abducted 90-degrees and maximum external rotation. The examiner typically will support the humerus with one hand while applying overpressure to the external rotation of the shoulder. A positive test will result in the patient reacting to the movement by preventing further rotation or appearing apprehensive. It is at this point that the relocation test is typically administered.

Shoulder - Adson's Test
Adson's test is used to assess for the presence of Thoracic Outlet Syndrome at the scalene triangle. The patient is examined standing. The examiner palpates the radial pulse while moving the upper extremity in abduction, extension, and external rotation. The patient then is asked to rotate her head toward the involved side while taking a deep breath and holding it. A positive exam will result in a diminished or absent radial pulse.
