Adson's sign is the loss of the radial pulse in the arm by rotating head to the ipsilateral side with extended neck following deep inspiration. It is sometimes used as a sign of thoracic outlet syndrome (TOS). [ 1 ]
Thoracic outlet syndrome (TOS) is a condition in which there is compression of the nerves, arteries, or veins in the superior thoracic aperture, the passageway from the lower neck to the armpit, also known as the thoracic outlet. [1] There are three main types: neurogenic, venous, and arterial. [1]
Wright's test is a clinical sign in which the radial pulse weakens or disappears when the arm is abducted and externally rotated. [ 1 ] [ 2 ] It occurs in some patients with thoracic outlet syndrome .

Adson's sign tests for thoracic outlet syndrome Lhermitte's sign may indicate cervical radiculopathy or spinal cord disease Spurling's test tests for cervical spine disease [ 1 ] [ 2 ]
A positive Pemberton's sign is indicative of superior vena cava syndrome (SVC), commonly the result of a mass in the mediastinum.Although the sign is most commonly described in patients with substernal goiters where the goiter "corks off" the thoracic inlet, [4] the maneuver is potentially useful in any patient with adenopathy, tumor, or fibrosis involving the mediastinum.
Professional societies such as the American Thoracic Society and the European Respiratory Society have published guidelines regarding the conduct and interpretation of pulmonary function testing to ensure standardization and uniformity in performance of tests. The interpretation of tests depends on comparing the patients values to published ...
The superior thoracic aperture is essentially a hole surrounded by a bony ring, through which several vital structures pass. It is bounded by: the first thoracic vertebra (T1) posteriorly; the first pair of ribs laterally, forming lateral C-shaped curves posterior to anterior; and the costal cartilage of the first rib and the superior border of the manubrium anteriorly.
