1. A portable automatically controlled electrical tissue stimulator comprising:

  • means for producing electrical stimulation current, the polarity of said current controllable by a current control signal;

    a plurality of electrodes for attachment in an array to a patient to be treated;

    multiplexing means operatively connected between said current means and said electrodes, and responsive to a multiplexing signal for selectively connecting any pair of electrodes to said current means; and

    presettable automatic control means including memory means for storing presettable digitally encoded information indicative of a desired sequence of electrode pair connections and a desired number of current pulses to be applied to each of the pairs connected in the sequence and further including means responsive to said information stored in said memory means to produce said multiplexing signal and said current control signal to cause said electrodes to be sequentially connected to said current means automatically and stimulation current pulses of alternating polarity to be delivered to said pairs of said electrodes automatically.
