I am a graduate student at the University of Maryland Eastern Shore. I am currently working on a study involving E-stim and it's effects on motions sickness. There is little published on E-Stim in particular, but I believe Dundee in Europe has published two studies on the effects of P6 stimulation by E-Stim in both pregnant women and post anesthesia patients. Good luck......dave bender %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
