Thank you everyone. I will definitely seek another opinion from a neuromuscular expert.
In the meantime, what do the people who have experience reading EMGs think? Which were the most common findings in your own EMGs?
To be more precise, for what I've been reading this is necessary for a diagnosis: "The needle EMG is the most important study in determining diagnostic certainty of ALS. Acute (denervation evidence via presence of PSW, fibrillations, and FPs) and chronic neurogenic changes (as evidenced by decreased MUP recruitment with rapidly firing and reduced numbers of MUPs, as well as large amplitude, long duration MUP) is required for diagnosis of ALS."
I have FPs (everywhere but in the tongue, trapezius, and interosseus), scattered PSW and decreased MUP recruitment, but I have no fibrillations or long-duration MUP. I also have no clinical signs of LMN involvement (weakness, atrophy, weight loss, or visible fasciculations), but I have clear signs of UMN involvement. How relevant are the results of this EMG in the opinion of those of you who have lived with the disease? I will reiterate that I have more than two years of symptoms, so this is hardly the case of an early-disease EMG.
Thank you
