Did the dr ordering the tests suspect TOS , or just was doing a basic test for generic reasons..
I think they should have done arms down & arms up..
but an arms down indicator would be more serious - like possible full time blood flow restrictions vs only when arms raised..
You can use our site search tool for test keywords, symptoms and such to find past posts or threads mentioning those.. https://www.neurotalk.org/search.php

I haven't had that test but my chiro , PTs & primary did see my " white hands" and loss of coordination after a minute of raised while making gripping motions and then flushing when lowered. The stick em up test LOL
