Abstract
A method and apparatus are disclosed for providing therapeutic electric current to a treatment site of a patient. The steps of the method comprise generating a first and second signal having a frequency difference between 1 Hz and 300 Hz, wherein each signal has a frequency of at least 1 KHz and are amplified by Class D switching amplifiers, minimizing the DC component of the first and second signals using balanced amplifiers; operatively coupling a first electrode of at least one pair of electrodes to a patient's body on or beneath a first epidermal or mucous membrane surface; operatively coupling a second electrode of at least one pair of electrodes to a patient's body on or beneath a second epidermal or mucous membrane surface; forming a therapeutic signal configured to reduce pain at a treatment site by simultaneously sending a first signal from the first electrode to the second electrode and sending a second signal from a second electrode to the first electrode, and then simultaneously sending the first signal from the second electrode back to the first electrode and the second signal from the first electrode back to the second electrode, wherein the first and second signals are linearly independent off phase alternating current signals; and adjusting the therapeutic signal utilizing a feedback system based on impedance changes within the patient's body.
