Can you tell me if emg tests can be normal with primary lateral sclerosis?

In brief: Would be unlikely

If motor neuron disease exists, and could be in form of primary lateral sclerosis, there will usually be some degree of EMG pathology.
A fully normal EMG would tend to rule against a diagnosis of any kind of motor neuron disease, but early on, findings might be very minimal and the test might need repetition in several months.
