Please can someone tell me if an EMG done in the limbs can detect bulbar als?

[AnxiousWorrier85]

I need to move last this fear, and I thought having an EMG would help me do that and it did at first…
Been twitching in my calf’s, thighs, arms and other random spots for 4 months now.
Clean clinical examination and an EMG on both legs and upper and lower right arm was perfectly normal. (They tested the limbs where I was getting fasciculations most)
Initially I was relieved and then yesterday and again today I randomly coughed on some water I was drinking and now I’m terrified of Bulbar als and that the EMG might now have shown that?

Please can someone snap me back into reality and try and explain how an EMG works please?

Am I right in thinking if I had twitching (which I have had for 4 months) which was due to als then by testing those affected limbs the EMG would have picked it up no matter where the onset ie bulbar because the twitching was my initial symptom which led me down this rabbit hole in the first place.

Your questions are best directed at your neurologist, but even then you will be lucky to get a definitive answer. We all have to soldier on and wait and see what happens. Neurology is very much await and see game.

I am sorry that I can't help further but on the other hand you are still functioning unlike many of us.

Take care xx
