The goal of this study was to determine the optimum level of current intensity in treating hyperhidrosis. Utilizing between 7.5-8.0 mA proved to be the ideal level, as efficacy was highest while avoiding an increased incidence of side effects. Typically, patients undergoing this degree of treatment experienced roughly a week of palmar dryness before returning for treatment. Side effects included dry mouth and throat, and this was experienced by most patients. Current intensities above 8.0 mA resulted in higher frequency of side effects occurring, however the length of time patients experienced side effects was not impacted by the current intensity.
