- Learn about ALS
Hi everyone, my dad was recently diagnosed with flail arm ALS. He has had it for approx. 2 years. He had a EMG in Feb 2020, NoV 2020 & May 2021. All 3 EMGs showed changes in arms, everywhere else is normal on EMG. The EMGs were not hugely different according to neurologist. Between the 2nd and 3rd EMG, there is approx 6months and we notice quite a bit more functional decline. Its so much worse than last fall or even last winter. Yet the EMG doesnt reflect a huge change. Neurologist said something about percentiles? Can anyone maybe explain that? Thank you.
