Abstract

A device and method are set forth for electro-stimulation. The user can select an overall treatment protocol of current frequencies and amplitudes to be applied for specified dwell periods defining a sweep cycle. The user can select for one or more periods in the cycle a frequency/amplitude to be applied to elicit a response such as a muscle contraction or the like. The device protocols may be selected to elicit responses while conserving power, to provide for heating without eliciting a response or to hop between frequency/amplitude combinations to produce the desired effect.
