I'm not a moderator here and I don't have MS but I found this YouTube video that shows what you heard about
. I have no idea if this is really effective. In short, the patients bit down on what looks like a tongue depressor sticking out of their mouth and there seem to be a couple of pressure points on the mid section of the body that are pressed. I can't say one way or the other about
if it would really work on a person with MS or Parkinson's.
