I think the Iqoro has made a difference for me. It's been over a year now and I'm using it 3 times a day for 30 seconds each time. I found a pamphlet from Iqoro where I had done their swallowing test at the beginning. Time yourself drinking 1 dl (deciliter, about half a cup) water. I wrote 15 sec. Tested now and I can drink the same amount in 10 sec. My swallowing is better!
