A year is not that long
Every case is different, for sure, but there are a lot of people who have had some improvements years after the onset of GBS. I am one of those. I have really spent lots of time rehabilitating but progress has been very slow in some areas. Just to give you one example, I have been doing this video exercise that has lots of balancing positions on one leg – very low impact. I started doing this in October 2008 and it honestly wasn’t until about two months ago, when this became easy for me to do with my right leg (my left leg was able to do them more than a year ago). I’d have bet a million dollars it wouldn’t have taken so long if someone bet me 2.5 years ago. But that is what happened. Many of my recoveries, like walking without crutches, and walking normally, also took lots longer than I could imagine. So while I don’t want to raise your expectations unrealistically, I don’t think that in most cases, progress only occurs in the first year.
