Hi,
I don't get these questions.
Your research project is supposed to be your own work, from coming up with a research question to writing the whole thing in the appropriate format.
Have you ever treated people after CVA? Don't you have just about a million questions left?
I still have, even after 20 years working with them. But that won't help you, because you need to find your own question, in order to have the interest and motivation to undertake the study and search for literature.

Just think about, what frustrated you most when treating people with stroke, or think back to the times, when you tried to find literature to guide your treatments. Did you find any gaps, things that haven't been researched well, ... or ... go the other way. Anything you read that really got you thinking that you would like to try yourself and check whether it works with your special clientele or age group???

Just a few thoughts.
Good luck,
Fyzzio
