I notice more and more exhaustion, even for smallish efforts. The Exertion Intolerance Syndrome (EIS) appears to progress. I also have more challenges with balance. As a result, I decided to give up rowing, since the pleasure to strain balance became totally out of whack.
Occasionally I have a day, where my hands loose aim on the piano and clavichord, but when I employ the techniques I use at the onset of Parkinson’s, I can regain control of my playing.
