1. Adson’s Test, How the test is done and the anatomical basis of this test Kelompok 2

2. Adson Test Adson test is designed to assess anterior scalene syndrome, one of the four forms of thoracic outlet syndrome A hallmark of TOS is the reproducibility of symptoms with specific arm and shoulder movements. The maneuvers are designed to target specific anatomic areas that are commonly implicated in TOS in order to reproduce symptoms of pain, paresthesia, or pulselessness.

3. How the test is done Test Maneuver Positive Result Adson Test The affected shoulder is abducted to 30 degree with full extension of the elbow. Patient extends the nect while turning their head to the ipsilateral shoulder and inhaling deeply Diminished or absent radial pulse

4. Technique and Procedure The test can be performed with the patient in either sitting or standing with their elbow in full extension The arm of the standing (or seated) patient is abducted 30 degrees at the shoulder and maximally extended. The radial pulse is palpated and the examiner grasps the patient's wrist. The patient then extends the neck and turns the head toward the symptomatic shoulder and is asked to take a deep breath and hold it. The quality of the radial pulse is evaluated in comparison to the pulse taken while the arm is resting at the patient's side. Some clinicians have patients turn their head away from the side tested in a modified test

5. Positive Test 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. A positive test should be compared with the non-symptomatic side

6. Anatomical Basis of Adson Test A nterior scalene syndrome is a neurovascular entrapment syndrome caused by tight anterior and middle scalenes , T he idea is to stretch and pull these muscles taut, causing them to further compress the brachial plexus and subclavian artery, which run between them.

7. Anatomical Basis of Adson Test Adson’s test involves asking the client to rotate the neck ipsilaterally, flex it laterally to the opposite side, and extend the neck at the Spinal Joint (the opposite actions of the actions of the anterior and middle scalenes ), while the therapist is palpating the radial pulse
