Hey Rick, I think I've "met" you over at patients like me or another PD forum.

I am looking at buying a well rated yet inexpensive GSR bio feedback device to improve my concentration & focus.

In the past, before PD, I have been able to focus very clearly, sharply &
deeply for long stretches, but now....

Which brings me to my second ?: has anyone here used a biofedback device to work with stress reduction and/or focus sharpening?

If so, what is the effect on the PD symptoms?

George
