Purpose
[edit | edit source]
Adson's test is a provocative test for Thoracic Outlet Syndrome accompanied by compression of the Subclavian artery by a cervical rib or tightened anterior and middle scalene muscles.[1]
Technique[2]
[edit | edit source]
- Patient in upright position.
- Passively extend, abduct and externally rotate affected arm while palpating the radial pulse.
- Ask patient to take a deep breath and hold it in.
- Ask patient to extend neck and rotate the head towards affected side.
The test is positive if there is a marked decrease, or disappearance, of the radial pulse. It is important to check the patient's radial pulse on the other arm to recognize the patient's normal pulse.
Evidence[edit | edit source]
There is minimal evidence of its interexaminer reliability according to existing literature. It has been noted to have a specificity ranging from 18% to 87%, and sensitivity of up to 94%. There is little documentation regarding the reliability of the adson's test. [3][4][5]
