I am sorry you are having so much trouble finding help. It is indeed a trial and error process.
Our Neuro. ordered swallowing tests and CT scans and two sessions with a specialist who explained the swallowing process and PD. She then gave us exercises, suggestions for eating and diet ideas for now and the future.
He drinks a lot of Gatorade and Ensure, and of course Ice Cream. Chewing tires him, so I cut his meat in very small bites, and we have finger foods which he can pick up. Mealtime is a very tiring and takes about 2 hours, because he drifts off to sleep, wakes up, eats some more...etc.
As to the fork: He finds the short desert forks much easier to handle. Not only is the handle shorter, the tines are also shorter. Also, as I cut his meat, or broccoli, etc. I usually feed him some, so he can chew while I cut his food. Yes, mine gets cold sometimes, but I am saving him some work by helping.
