Chris, When Dr. Verhagen visits you this week will you be sharing with him the successful stimulator setting perameters that you have found? I hope he can learn a lot from you. My last setting has me confused. When I left the office at the clinic I was off drugs for 6 hours and only on the stimulators, I could walk slowly but reasonably well. And my finger taps were pretty good. But now at night when my last medication wears off I slow down to where I can barely walk - my steps are tiny and rapid and I almost unable to function. I don't understand why ? Can you offer any explanation? I would think that the stimulator should be more of a factor than it appears to be. Marty
