Claim:
1. An electro stimulation system for providing signals to a subject including: a first electrical current control circuit (i) adapted for connection to a first electrical power supply such that electrical current supplied to the skin tissue of the subject is controlled and (ii) providing a first electrical current return path; a second electrical current control circuit (i) adapted for connection to a second electrical power supply such that electrical current supplied to the skin tissue of the subject is controlled and (ii) providing a second electrical current return path; a plurality of first connection probes adapted for temporary external electrical connection to the skin of the subject; a plurality of second connection probes adapted for temporary external electrical connection to the skin of the subject; a first active switching device for intermittently connecting an output of the first electrical power supply to one of the first connection probes thereby causing the one of the first connection probes to become an active probe; a second active switching device for intermittently connecting an output of the second electrical power supply to one of the second connection probes thereby causing the one of the second connection probes to become an active probe; a first return switching device configured for intermittently connecting one other of the first connection probes to the first electrical current return path thereby causing the one other of the first connection probes to become a return probe; a second return switching device configured for intermittently connecting one other of the second connection probes to the second electrical current return path thereby causing the one other of the second connection probes to become a return probe; a first electrical resistance configured to be connected in parallel with active and return probes of the first connection probes; a second electrical resistance configured to be connected in parallel with active and return probes of the second connection probes; and at least one switching control device connected to the first and second active switching devices and to the first and second return switching devices, wherein the at least one switching control device is configured to be activated during a treatment to cause a repeatedly varying selection of different first and second connection probes as active probes or return probes causing a varying formation of electrical currents passing through a path through the skin tissue of the subject with an electrical current being established (i) between an active probe of the first connection probes and a return probe of the first connection probes and a return probe of the second connection probes simultaneously during a treatment and (ii) between an active probe of the second connection probes and the return probe of the second connection probes and the return probe of the first connection probes simultaneously during the treatment.
