the ST gave us a bunch of exercises to improve breath control, mouth muscles and tongue and throat muscle control and tone. I looked pretty goofy doing them but after some time they did actually help. They do a lot of this for all sorts of neuro patients - that's important that you see a speech therapist who specialises in neuro (mine was at a stroke rehab center & I was the only patient under 50 when I went). I also got lots of swallow testing (yum, pudding) from her. Mine was even covered by insurance (I never knew such a program existed on my insurance).
Try it - it helped me and it can't hurt. Now stop worrying about the future- just keep plodding toward it (I have it on good authority that it is the only way to get there

)
