Look into Vitalstim therapy.
www.vitalstim.com My husband had similar swallowing difficulties after his treatment ended 4/05 and is making real progress using this treatment. He has reduced his pegtube consumption by 50% and is gaining weight!!!! He started this therapy in late March, and for the first time we have hope for some normalcy. We are realistic, if he doesn't progress any further we will be greatful for what we have.
