Hi, Debbie,
Having seen a fair few of your posts, I suspect that this question is coming FROM somewhere......

Is this how researchers rate and log progress through studies?

I don't see how it can be a great way to do things.

If someone said 'I will see you every six months, and rate you, but take your meds at the same time and I will see you at the same time' still some people might display widely fluctuating rates of ability. Especially if they had cheese for lunch.....

As someone (thanks, Kath, for saying it for us all!) said just today, a PD patient could be different hour to hour!

My doctors preferred method of seeing how I am doing is getting me to walk 2 yards to the door, turn around, and walk back with my arms stretched out in front of me, like something from Carl Hernz's pd zombie movie, on the WPC site now! If you haven't seen it yet do so!
