hi Adam,
I would also suggest you to go for same thing ...that get urself examined by a physio. Because the information which you hav given is not at all enough to guide you also.
What structure in ur brain is involved? what is the stage of recovery right now?
what is ongoing therapy?...any more thing we need to now before giving a single word of suggestion.
So it will b better if u get ur exercise programme get ready through ur personal physiotherapist..........n remember it is needed.
