-----Oorspronkelijk bericht----- Van: Tom Riess <[log in to unmask]> Aan: [log in to unmask] <[log in to unmask]> Datum: maandag 29 november 1999 21:16 Onderwerp: DBS SURVEY Hi Tom, I think your survey may be very useful, but I would like to make some comments: 1 In Belgium the about 90 patients that underwent DBS of the GP or the STN have formed a supportgroup and their answers to your survey may be useful. If you are interested I can give you the emailaddress of the coordinator of the group. 2 There are DBS's of GP, Thalamus and STN. Also there may be a difference in L/R, one or both sides. 3 Also can be important what kind of surgery was performed before the DBS. (pallodotomy L/R, thalamotomy L/R, DBS of GP L/R). And how long ago did they have the(se) previous operation(s)? 4 Not only the (change of) voltage is important and/or can be essential for the result. Other issues are: the EXACT target location, the number of electrodes used, the positions of these electrodes related to the target and eachother, the polarity of the electrodes, the used frequencies. 5 I suggest you ask dr. van der Linden if he is available to help you define all relevant questions about DBS's. Hans.
