Are there any adverse reactions from using the electrodermal devise?
The output electrical stimulus of the electrodermal devise is 10-12 microamperes, about the same amount of amperes produced as a AAA dry cell battery. It is classified by the Food and drug administration as being of non-significant risk. About 200 grams of pressure must be applied in order for the probe to make proper contact with the skin. As a result, a pressure mark may be made at the contact point of the skin with the Cramer needle of the probe. This mark disappears rapidly without any residual effect. Adverse biofeedback reactions are unusual. The only one that I have seen in 1310 cases is vasomotor instability produced by imprinted solutions for chemicals or metals affecting the parasympathetic nerve site , ST 10a or the Autonomic Nerve site, AL 1a. Most of those who experience these reactions felt better in the recumbent position until the reaction clears.
