Although diagnosis and treatment of TOS is common in osteopathic medicine, the effectiveness of the diagnostic special tests and treatment has not been thoroughly investigated. This study aims to examine the effectiveness of the special tests (Adson's, Wright's hyperabduction and Halstead maneuver) in diagnosing a change in blood flow through the arteries of the upper arm compared to evaluation with Doppler ultrasound to measure blood flow while the tests are performed. Patients with positive tests will be treated with OMT including myofascial release, soft tissue, and articulation to relieve restricting structures. Upon completion of treatment, the special tests will be performed again along with the Doppler ultrasound to measure blood flow through blood vessels. Results then are analyzed statistically for significance of the ability correctly diagnose and treat TOS symptoms.
