TENS / EMS Muscle Stimulator Machine as Iontophoresis Machine

Had anyone used a transcutaneous electrical nerve stimulation (TENS) or electrical muscle stimulation (EMS) machine as an underarm iontophoresis machine. Traditionally, these machines are mainly used to rehab muscles and prevent atrophy of muscles when a person is injured and unable to exercise. Take a look at some of these:

It seems to me that one of these machines could easily be used simply by placing the electric charge side back to back and wrapping them in a wet cloth. I've tried the drionic underarm unit, but the batteries die quickly and are expensive to replace.

I have been wondering if this machine can be used for iontopheresis for palmer and planter treatment? I was thinking about getting it to use for pain related issues and if it can serve a dual purpose.

i think it would, so long as you connect it to a metal pan with water that is grounded underneath.

It's been years since this posting. A TENS unit will NOT work for ionto treatment because it is AC. Obviously I didn't order the above unit and went with the Galvanic Stimulator which has been highly successful.
