Okay, Ballerina, here are the full details:

We are delivering the standard 2.0 mAMP for 20 minutes, resulting in a total dose of 40 mAMP minutes. She tolerates this okay.

We are using anodal stimulation (I incorrectly wrote cathodal stimulation in prior post), with the red (positive) lead over the right motor cortex (contralateral to the area of her worst pain, on the left side of her coccyx/perineal region), and black (negative) lead at the left supra-orbital position. Everything I've read suggests anodal stimulation of the motor cortex to be most efficacious for chronic pain.

We are using the following system components to deliver the current:

1) Iomed Phoresor II Auto iontophoresis device

2) 3" x 3" Amrex rubber pad w/ sponge insert (actually 2" x 2" contact surface with skin; 25.8 cm2)

3) pin to banana pin adaptors (to insert into the rubber pad)

4) (3) snap to pin converters (to connect between the electrophoresor's wires and the pin to banana pin adaptor)

I bought these >2 years ago, and tried to list the websites I purchased them from (still valid)**edit**

Again, my question is simple: are you finding a lead position that works better than that which we are using? If so, what is it, if I may ask? I hope you have continued to experience improvement.
