sorry, noname, but i have to respectfully tell you, i think it is a little bit irresponsible to encourage people with neurovascular injuries and/or entrapment disorders to try to "push through the pain" using yoga poses such as the one you describe. and to do so without the input of a trained PT, no less, beforehand? sheer madness, i say!
in fact, we have at least one forum member whose very injury was caused if not severely exacerbated by doing this very type of thing. now, perhaps you are young enough or your TOS mild enough that you can still get away with doing things of this nature. but i certainly wouldn't advise anyone else to try it...
that is just asking for trouble, in my humble opinion. TOS is a very harsh taskmaster. it is nothing to fool around with and a confounding thing, to say the least. what feels like muscle pain is really nerve pain, and vice versa. the nervous system is in a constant state of hyperexcitement due to injury to and/or ongoing compression of the BP, and the involved musculature is in a constant state of spasm in a futile attempt to protect the affected nerves and blood vessels, and 'round and 'round she goes, where she stops, nobody knows...
ayenga yoga taught one-on-one by a certified instructor trained to work with people with injuries is one of the few forms of yoga i can tolerate, personally. and i cannot even do that right now. yoga simply has too many arm movements for me and for many other TOS'ers that i know. so does t'ai chi... and i LOVED doing t'ai chi when i could manage it!
so i think it's great that you have gotten your TOS under control, or that your case is not that advanced, or whatever the case may be for you personally. i'm just a bit nervous about putting specific movements up on a board like this one that someone else may unwittingly then try for themselves, with potentially disastrous results if not closely supervised by a trained and caring professional.
i know that's not your intention, but you see my point, i'm sure (i noticed you say you're in the minority view; perhaps that is what you meant by that remark?). i am all for PT, bodywork and other modalities, home programs including yoga, don't get me wrong! just easy does it. we don't want anyone to reinjure themselves. and with the TOS personality, it's just too easy to do!!!!
so even though you don't expressly say everyone should try to do this certain yoga move, it worked for me - there is a danger that someone might do exactly that. that is my point. nothing more, nothing less. i hope you won't take offense at what i'm saying here. i just don't want anyone getting hurt (more hurt than they already ARE, i mean).
and oh, just as an aside to bill: FYI - the nerves that comprise the BP (C-5, C-6, C-7, + C-8 & T-1) branch out to become the 3 main ones in the arm that you mention, median, radial and ulnar. so these are not SEPARATE dx's or issues for you, my friend. it all falls all under the TOS umbrella, i'm afraid!

you may have some double- or triple-crush issues going on, but i'll bet you even $ the original injury was in the BP. that's where the trouble began, and that is what set you up for the nerves to become vulnerable elsewhere as they travel down that big strong arm of yours...
but fear not! now that you have the right dx and the good doc fried, help is on the way. hey, have you heard of a PT named suparna over in allentown? i've heard she is running one hell of a program over there... check it out, bill! googlebreath! i want to go stay there for 8 weeks but i need shelley to take a roadtrip with me and she's all talk and no action, apparently...
bye, kidz. and no offense, noname. i wish you had a name and i always enjoy reading your posts, because we need different viewpoints to keep this forum alive and the info flowing!
