Hey Alice,

This might be a really weird question, but where would the needle be inserted for SFEMG if a person has respiratory weakness? I know that for me, they put the needle in my forehead because I had facial weakness (or maybe they were checking my ocular muscles, not sure...I didn't have ptosis or dv at the time the testing was done, though)...This is why I think that it would be odd to use SFEMG in a case where a person has mainly respiratory weakness, just because I have no idea where they'd put the needle...I'm prollly totally missing something....But it seems that if that is the case (that it wouldn't be possible to measure that sorta weakness with that sorta test), they should base the diagnosis on symptoms, response to meds. and/or blood tests (if the weakness is isolated to the breathing area)...
