No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
The hypothesis is that CES stimulation will dose dependently increase parasympathetic tone. Healthy subjects will have three 20 minute sessions of CES stimulation, at three different intensities of stimulation, with each session occurring on a separate day. Effect on parasympathetic tone will determined by measuring high frequency heart rate variability before, during and after the stimulation. The Fisher Wallace Stimulator (FW100) which delivers a low dose alternating current a varying frequencies will be used for the stimulation.
