  1. – maximum value of the current density (J z ) along the median nerve or ulnar nerve. – average value of J z for 10% of the elements with highest J z values along the corresponding nerve; – average value of J z in the respective nerve. Ratio – represents the ratio of in the stimulated nerve related to for the nerve, which is not to be stimulated.
