The test shown in the picture above represents Adson’s sign which is the loss of the radial pulse in the arm by rotating head to the ipsilateral side with extended neck following deep inspiration.
Process
- The patient is placed in a sitting position, hands resting on thighs.
- The examiner palpates radial pulse on side being tested
- Patient actively rotates head to ipsilateral side being tested while the examiner laterally rotates and extends the patient’s shoulder
- Patient takes a deep breath and is instructed to hold it
The test is positive if radicular symptoms are reported and secondary to a diminished or lost of the radial pulse.
