The tiny brain trainer that helps get you moving after a stroke

Is this vagus nerve stimulation now considered a standard protocol?

Sends signals to activate nerve to prompt brain to release neurotransmitters

The National Stroke Association has a story of a person getting one but absolutely no information on who it might be useful for. What kinda crap information is that?

The American Stroke Association has no information on vagus nerve stimulation. It must not be important.

The World Stroke Organization has no way to search their site probably because its totally useless for survivors.
