Adson Test | Thoracic Outlet Syndrome

Adson Test | Thoracic Outlet Syndrome


Hi and welcome back to Physiotutors. I’m Kai and in this video I would like to show you the Adson Test, which is another test for Thoracic Outlet Syndrome. According to Gillard et al. in 2001 it has a sensitivity of 79% and specificity of 76%. With this test you are testing the entrapment of the Brachial Plexus between the anterior and the middle scalene muscles which form the posterior scalene port. So let’s get to it. To do the Adson Test Bring your patients shoulder to the external rotation slight abduction and little bit of extention and try to palpate his radial pulse. Then ask your patient to extend his head and to rotate towards the tested shoulder. And ask him to breathe in and hold the breath For little while. For this test to be positive you are looking for the reproduction of your patient’s symptoms or for abolition of the radial pulse. Alright guys, this was the Adson Test which is the most valid test on the Thoracic Outlet Syndrome according to the Gillard et al. in 2001. I hope you enjoyed this video Please make sure to check out the other tests that we covered on Thoracic Outlet Syndrome. and see you next time.

  1. Ontzettend bedankt voor alle nuttige video's die jullie posten! Het maakt mijn leven als fysio student veel makkelijker 😉

  2. The symptom of this test (looking for diminished radial pulse can create a false positive test). Therefore, this test should only be used to search for symptom provocation

  3. Shouldn't he look (rotate his head) towards the other way in order to stretch the scalene muscle and reproduce the symptoms?

  4. great video guy! question: if this test is positive, for treatment purposes, would you target the middle and posterior scalene? thanks!

  5. Always good content on this channel! To your knowledge is there any tests that give preference to the more common neurogenic component of TOS or because of the anatomy's proximity are all structures within the outlet being tested?

  6. I'm using Magee as my source, the procedures, in this video, are correct. By the way, thoracic outlet syndrome (TOS) is due to the following: tight scalene, cervical rib compression, surgery, or pancoast tumor. Therefore, you are going to perform some stretching to the patient's scalene.

  7. How's it called the posterior scalene port if it lies between both the anterior and middle scalene muscles, and not between the middle and posterior scalenes?

  8. i would to ask you about allen test .roos test adsons test is all of these test for dx brachial nerve injury ?

  9. I'm a RN and I have TOS, I let the resident doctors practice these tests on me all the time in the ER, they are always shocked to feel my radial pulse decrease so rapidly.

  10. Hi guys, awesome video! I have a few questions about this test. I've read online that this test is to determine compression of the costoclavicular space. Is this true? Also, assuming costoclavicular space compression, how does someone fix this conservatively? Which muscles need to be strengthened and which muscles need to be stretched? Thanks in regards
