Morley Test

The best test to assess thoracic outlet syndrome (TOS) is typically a combination of clinical maneuvers, including the Adson's test, Wright's test, and Roos test, which evaluate for compression of the brachial plexus and subclavian vessels.

Electromyography (EMG) and nerve conduction studies (NCS) are commonly used to confirm brachial plexus injuries by assessing nerve function and detecting abnormalities in electrical activity along the nerve pathways.

To test for thoracic outlet syndrome, perform clinical maneuvers such as Adson's test, Wright's test, and Roos test. These assess for compression of the brachial plexus and subclavian vessels in the supraclavicular region, typically reproducing symptoms like pain, numbness, or tingling in the upper limb.
