I think what you meant to say is the motor unit potential. If those are of normal size, then that means you don't have chronic denervation, which is an excellent sign.
You don't mention positive sharp waves or fibrillations, which would be indicative of active denervation. The absence of these is another excellent sign.
The fasics you are having in the absence of weakness and in the absence of atrophy and in the absence of positive sharp waves and in the absence of fibrillations and with normal motor unit potentials, is excellent news too.
Fasics will be picked-up by an EMG whether they are from ALS or BFS or any other reason. It doesn't matter how many there are, the EMG will see them. Your neuro would be able to tell whether they were benign or pathologic and if your neuro cleared you, then they are benign. Once again, excellent news.
Put all of this together and you have nothing but fantastic news. Congratulations. You should now go out and celebrate. This is going to be one great 4th of July for you. Take care.
