Barry - I'm sorry, we don't know what changes the nurse-clinician made in Dick's programming. There are five variables, as you probably know. I think she said one changes was to increase the amplitude, but I don't remember what the other change was. I don't think knowing the changes made to Dick's stimulator would necessarily help you - everyone is different, and their programming needs are different, too. Dick's surgery was at KU Med, where they've done more DBS surgeries than anywhere else in the country. I think experience plays an important role, both in the placement of the electrodes, and in programming the stimulators afterward. The nurse-clinician we see does nothing but program stimulators all day long. She's so experienced she was able to guess what changes would help, and with just a couple of keystrokes typed in the changes. Her first guess seemed to be the right one. Dick will go back in a couple of months, where he's scheduled for an all-day session, which will include "tweaking" his stimulator settings more to see if we can gain even more improvement. Best of luck to you. Margie << So what are these changes , dont keep us in the DARK I need some changes as my benefit from the op 2 years ago is gradually deminishing and my doctor has made many adjustments with out a great deal of progress. >>
