Hi Voner,

Question #1 I did the C3 protocol when I was treated at Beth Israel and had a positive response. The researchers were pretty exacting about precise location. That kind of precision was necessary because they were primarily a research institution. The electrodes are big enough that they cover many areas so getting it close is good enough. You can use diagrams for the 10-20 system, use the percentages to find the location. (You can find the 10-20 by doing a google search, try EEG Measurement and Setup, or EEG 10-20 International System) After you find it pm me if you have any questions.

I have tried three other protocols, (electrode placements) two had no effect and one worked better.

Question# 2 3" pads are the standard electrode at the three treatment centers in the U.S.

Question # 3 I had to kiss a lot of toads before I found my Prince PM and Neuro docs. In addition to consulting with top Drs. in tDCS, I find it very beneficial to have a partnership with both a PM and a Neuro. It also helps that they are on the same page, particularly regarding invasive procedures and CRPS.

Don't give up on Docs. Finding a good fit can be very hard. The hardest part with having CRPS is learning what defines a good fit.

Hope this helps!
