During which test is axial load applied while performing internal and external rotation of the shoulder?

The Compression Rotation Test is the correct answer because it specifically involves applying an axial load to the shoulder while simultaneously performing internal and external rotation. This test is designed to assess the integrity of the glenoid labrum and to identify any potential labral tears or issues related to the shoulder joint.

In this test, the axial load compresses the shoulder joint, which can provoke symptoms if there is a pathology such as a labral tear. The rotation component of the test further stresses the labrum as it is subjected to shear forces, enhancing the likelihood of reproducing any symptoms associated with underlying shoulder pathology.

In contrast, other tests listed do not incorporate axial loading with internal and external rotation in the same manner, making them less suitable for this particular evaluation. Therefore, the Compression Rotation Test's unique combination of loading and rotation makes it the appropriate choice for directly assessing the shoulder's structural integrity and function.
