Abstract
A system and method for interferential electrical current therapy wherein the region of beneficial interference may be positioned in the body of a patient by selectively controlling the electrical signal which is provided to each of two pairs of electrodes secured to the patient's body. Two electrical signals are provided which have frequencies that differ by a predetermined amount. The system comprises means for selectively amplifying, phase shifting, and mixing the second electrical signal with the first electrical signal and applying the mixed signal to a first pair of electrodes. The system further comprises means for selectively amplifying, phase shifting, and mixing the first electrical signal with the second electrical signal and applying the mixed signal to a second pair of electrodes.
