Research done on the effects of CES involved settings between 100-200 uAmp. At this low level it is difficult for human skin to feel the current. This means that the study participants could not tell whether they were receiving real or ‘fake’ treatment. Researchers did this to rule out the possibility of ‘positive thinking’ affecting their findings. To get the results you need with the Elexoma, 200 uAmp is more than enough.
The best intensity level for MET is found by increasing the voltage in increments until you can just feel a tingle. Stop once you feel this.
