microcurrents toner and lifter - for stroke?

I never saw this device anywhere in stroke rehabilitation so I wonder what caused it to be considered and then dropped. A type of eStim? I wonder if it could be useful to trigger finger contraction? So many questions and no one to ask them about.

Nuface Microcurrent Toner & Lifter $249

This is the most inexpensive facelift you can get. It uses micro currents to stimulate the muscles and create new muscle memory. It was first used on stroke victims and people with paralysis.. But just as you do with regular body exercise, you have to do this regularly or your muscles will lose their strength. I would suggest getting it done professionally first at a place such as Spa Radiance in San Francisco and then get yourself a home kit for $249. I guarantee you will see your skin lift and muscles in your face tone, no matter what your age.
