No, it doesn't. CTS is a problem with one area that the EMG shows but ALS can affect all the voluntary motor neurons but none of the sensory ones (that cause numbness and tingling).
The fact that someone does not have "typical" symptoms of something (and constant vs. episodic numbness/tingling doesn't necessarily correlate with CTS severity anyway) doesn't rule it out. On the other hand, lacking evidence of widespread lower motor neuron damage does rule out ALS. It's like, if you get in your car and drive it, then no one took the catalytic converter overnight, no matter how much you may be worried.
What a lovely non-ALS EMG! You must be so relieved that this should give you confidence to be able to move on and enjoy your life. We may not be licensed-neurologists, but we know ALS and you did not evidence it. The EMG backed this up. I'm so happy for you.
Thank you! I guess the only reason why I questioned it, is cause he said my symptoms don’t seem fitting of severe cubital tunnel syndrome, and I saw the spontaneous electrical activity in muscle findings, made me nervous. Thank you everyone
