Hi. I am 46 and last week went to neuro as I felt my left leg getting weaker. I do have undiagnosed SFN, which I thought was contributing to my weakness. I was surprised when the neuro stated that I had myopathy, never heard of it, and that he couldn't help me anymore. He was referring me to a neuromuscular specialist at Dartmouth Hospital.

I do not believe I have symptoms of nmd. I have twitching all the time, everywhere, but I feel this is benign.

I received the notes from the day of the emg visit last week and this was his interpretation:

Evidence of chronic, inactive, asymmetric myopathic process.
He then says, regarding myopathy, an inflammatory process is likely, perhaps metabolic.
Also in differential, muscular dystrophy. MND is remote consideration as well.


I'm hoping more will be clarified at Dartmouth. Can myopathic changes be seen in MND as well. From what I've read, there are distinct differences on emg in regards to these two diseases.

Any clarification would help. I know he uses the word remote, which is great. But still curious.

Thank you!

As you say the EMG of myopathy is different than that of ALS. Nothing in what you quoted seems to support MND as being in the differential. Do you have the full report? Are there psws and fibs? What does it say about recruitment, mups?

I am glad you are referred to a neuromuscular specialist who will certainly be able to clarify. You are also entitled to call and ask your current neuro to explain the apparent discrepancy

I am unable to post copy of my emg results here...want too. Can't find way.

No fibs or waves, a few Poly's(?)

Recruitment is lots of decreases, some normal.
Max pattern, lots of reduced +2 and +1.

Mup amp, mostly decreases.

Mup config, poly, triplets, doublets.

Ty for your promptness.

It does not seem to have the things we see in an ALS EMG. I would call and ask why it is in the differential?

Myopathy is good news. It means the disease is related to the muscles. In ALS the results are signs of chronic denervation, the disease is in the nerves.
Seems weird that ALS is even on the radar.

Ty so much for your thoughts. Not sure why. He didn't state anything regarding to my face. Just myopathy. Then I get his detailed notes and I wrote here what he wrote exactly. I do feel confident it is myopathy. Evidently he's not so sure. I do have nerve issues on right leg, but that's from aging discs. I'll have to wait and see. Thanks so much for your time good people.
