I only know what these kind of testing scales are like because of having a son who has had similar tests all his life. My testing was done by someone in a white coat, right before having an apomorphine challlenge, I was told what was happening, she did all sorts of scoring for things, declared that she thought I was developing a sensitivity to sinemet, told me she would be going on maternity leave, and I have never seen or heard from her since! By the time they actually got round to doing some of the mobility bit for the challenge, it was about 20 minutes too late, and I was pronounced not responsive to it.......

All these subjective things........

The thing I remember very well from that day is that she shoved a whole load of stuff and a large glass of water slipped off the edge of the table, and I moved faster than I had done in years - and that was before they administered the apo....... the glass didn't hit the ground of course, I caught it and got soaked...
