Those people that have had "clean" EMG's and then "dirty" ones had upper motor neuron symptoms or had PLS (PLS is a variant of ALS that only affects the upper motor neurons) that developed into ALS later (ALS is due to both upper motor neuron and lower motor neuron death). Upper motor neuron death will not show-up on an EMG and can only be diagnosed with a clinical exam. The symptoms you are stating (e.g. muscle atrophy) are lower motor neuron symptoms; if you truly have muscle atrophy and it was due to ALS, then you would have denervation and that would show-up on an EMG.
