Abstract
Wound healing therapy utilizing pulsed electrical stimulation is disclosed with the process including repeated short treatments of electrical stimulation applied to a soft tissue wound through an active electrode positioned preferably at the wound and with a dispersive electrode positioned at a distance from the wound. The active electrode positioned at the wound is normally caused to have negative pulses applied therethrough to the wound during a first treatment period of a treatment cycle, and thereafter is made to have positive pulses applied therethrough to the wound during a second treatment period of the treatment cycle, with the treatment cycle being preferably thereafter repeated one or more times in treating most wounds, and with the negative pulses causing debriding of the wound. Effectively treated soft tissue wounds include partial thickness and full thickness open skin wounds, and particularly chronic ulcers, burns, and skin flaps by way of example, with electrical stimulation being effected by both direct pad and hydrotherapy applications utilizing an electrical pulse stimulating unit capable of delivering pulses at a predetermined pulse intensity and rate.
