I've hesitated posting this, but I know people are going to keep reading this about the EMG and panicking if they think it might apply to them or their loved ones as well.
Generally speaking, the only EMG testing done for the bulbar area is the tongue. Not always, but usually. The tongue is innervated by the 12th cranial nerve.
Erica's husband does not have that much tongue weakness, but he does have a weak epiglottis. The epiglottis is innervated by the 9 & 10th cranial nerve, not the 12th.
If the facility he was tested at does not test the other areas for their patients, then the doctor is most likely taking this into consideration, as, after all she would know better than anyone what nerve is responsible for his problematic areas, and whether or not it was included in the EMG testing.
I'm not suggesting that they should not go for more opinions, not at all.
My personal experience was that I did have an EMG of my vocal cords, before one done anywhere else, and it was abnormal (vocal cords are 9 & 10th cranial nerve as well). A couple of months later I had an EMG of my tongue which was normal, (eventually it wasn't, but at first it was). So, before something like this becomes more global, it is possible to have a normal EMG, but receive this diagnosis, especially if the specific area of weakness was not tested with EMG. Even though testing is good, a doctor's exam findings play a huge part in what is determined.
I hope he is able to go to another facility for more opinions, but I understand, having gone through it, why they would be told this.
