During the Wright (hyperabduction) test, what is the position of the shoulder?

The Wright (hyperabduction) test is primarily used to assess for thoracic outlet syndrome, particularly how the brachial plexus and subclavian artery may be compressed as the arm is positioned in a specific way. During this test, the shoulder is placed in maximal abduction and external rotation.

This position is significant because it allows for the assessment of the space in the thoracic outlet as the arm is elevated. When the arm is in maximal abduction and external rotation, it can potentially exacerbate any compression on the neurovascular structures passing through the thoracic outlet. The test looks for a decrease in radial pulse or reproduction of symptoms when the arm is held in this position, which indicates potential thoracic outlet syndrome.

In contrast, the other positions mentioned do not effectively recreate the specific dynamic being evaluated with this test. Maximal abduction with internal rotation, maximal flexion, and neutral positioning do not achieve the same level of assessment for how the shoulder joint and surrounding structures might impact the thoracic outlet area. Thus, the correct answer reflects the specific position that maximizes the potential for identifying issues related to thoracic outlet syndrome.
