1. An electromyographic treatment system having a treatment device and including and operated by a computer having an interactive graphic display, the treatment device comprising:

  • a reference electrode and a pair of active electrodes for sensing electromyographic signals from a patient and for delivering an electrical stimulation signal to the patient;

    an electromyographic sensing circuit connected to the electrodes, having input signal conditioning means for converting the sensed signals to digital electromyographic words representative of the sensed signals and having an automatic nulling means for establishing a null signal level representative of a background electromyographic signal generated by the patient at rest;

    an electrical stimulation circuit connected to the active electrodes, having output signal conditioning means for converting a series of digital stimulation words into a plurality of complex, bipolar voltage pulses forming a series of preselected therapeutic pulse trains defining a stimulation signal;

    electronic interconnecting means for interconnecting the sensing and stimulation circuits and for interconnecting the sensing and stimulation circuits with the computer; and

    software means for use in conjunction with the personal computer for accepting the electromyographic words and generating a normalized image of the sensed signals for display on the interactive graphical display, enabling a therapist to view the sensed signals, enter a plurality of therapeutic parameters into the display, view a graphic representation of a resulting therapeutic pulse train, and for sending digital stimulation words representative of the therapeutic parameters to the stimulation circuit.
