Please check out "Frenkel exercises" on Wikipedia.
If necessary Google "Frenkel exercises".
These exercises do actually work!
They don't cure ataxia completely - not much does- but they certainly make the symptoms a lot better.
It's a pity neurophysiotherapists and many neurologists are often unaware the exercises even exist.
Heinrich Frenkel was a Swiss Jewish doctor who worked in Germany in the Nazi era.
His excellent books on the treatment of ataxia (in all its forms) was destroyed in Nazi Germany and most of Europe.
There are copies of his books in the Library Of Congress in the USA.
Love to all.
