I'm not sure what you mean. I had a "stimulated SFEMG," which got me a diagnosis after the two normal SFEMGs came back unclear. The stimulated SFEMG was just like the other SFEMGs except instead of telling me to slightly clench my muscles, they put electrodes on my face and sent pulses of electricity to make the muscles twitch.

These pulses of electricity were not in the least painful. They were very mild. It just felt like when your muscle twitches on its own. It doesn't feel like a shock.

I'm not sure this is the test you're having.
