The medical staff want to run tests on his throat. The tests are FEEST, Videostroboscopy, and modified barium swallow. I have looked them up, found lots of info BUT there doesn't appear info on what actual changes they can make. He has difficulty following directions and with a tube in is his throat expecting him to make different sounds, eating barium coated food all would be stressful for him, etc. Does anyone know about any of these tests and found them helpful? Aspiration pneumonia seems to be just a part of the progression of the disease. If these tests actually are helpful please let me know.
