"Tone" and "firm". Very non-specific, non-scientific terms. They don't mean anything to me.
You have to keep in mind that the stimulation is very light. So...it's not going to be a very effective way to stimulate a muscle. They're used in rehab because it's an effective way to isolate a muscle and it's easy to control the intensity of the contraction. That's their only effective place IMO. If you're completely sedentary, then it would be more beneficial than doing nothing. But still it wouldn't be very effective. The amount of calories that it would cause you to burn is pretty insignificant also, so it's not an efficient weight loss tool either.
