They have a 30-40% false negative rate, meaning that it will miss positive findings (or what should be) by the same.
On the other hand, the 60-70% chance that it will contribute to the diagnosis is very valuable. If you have a positive EMG, that is significant. If you have a negative EMG, you either don't have a problem or there is a 30-40% chance that the EMG missed finding your "positive" problem. It is still a necessary test to do!
If you have very strong clinical findings and the EMG is negative, very often it is repeated.
