  • Patent number: 4232680
    Abstract: The present disclosure relates to a method and apparatus for being used in transcutaneous electrical nerve stimulation. The apparatus includes a first circuit operatively coupled to a source of electrical energy for generating a squarewave output signal. At least two pads are provided for being placed in operative communication with the skin adjacent to the body sections of the patient to be treated. A second circuit is provided having an input operatively coupled to the first circuit and having outputs operably coupled to the pads. The second circuit amplifies the squarewave signal from the first circuit so as to deliver at the outputs thereof a predetermined constant current squarewave output signal representative of the input signal. In this manner the area of the body operably interposed between the pads will be treated by the squarewave signal having a predetermined constant current level which is independent of the operative resistance of the body section between the pads.
