Adson Test | Thoracic Outlet Syndrome Assessment<\/h2>\nThoracic Outlet Syndrome is defined as a neurovascular symptom complex associated with compression of the brachial bundle, which includes the brachial plexus and\/or subclavian vessels. This compression may be caused by several anatomical structures in one or more of the following three compartments: the interscalene triangle, the costoclavicular space or retropectoralis minor space.\n\nThe Adson test is designed to decrease the space in the interscalene triangle. According to Gillard et al. in 2001 it has a sensitivity of 79% and specificity of 76%. Regarding the rather low accuracy values and due to the fact the study did not make use of MRI as the\u00a0 gold standard, the clinical value of this test is rather weak.\n

Then the patient rotates and extends his neck to the tested side. This is followed by a deep inspirational breath which is held for up to 30 seconds, as the examiner palpates for any changes in the radial pulse. A modification is described with the shoulder in 15 degrees of abduction and the head maintained in the testing position for 1 minute while the subject breathes normally.\n\nThis test is positive, in case the radial pulse abolished or if the patient\u2019s familiar symptoms are reproduced.\n\nOther common tests to assess for TOS are:\n
