Electro stimulation treatment apparatus and method
First Claim
1. An electro stimulation system for providing signals to a subject including:
- at least one electrical power supply;
a first switching device for intermittently connecting the output of an electrical power supply to one or more connection probes electrically connected to the subject;
a second switching device for intermittently connecting one or more connection probes electrically connected to the subject to form an electrical current return path for current supplied by the electrical power supply; and
switching control devices connected to the first and second switching devices;
wherein the intermittent connection of the output of an electrical power supply or the intermittent formation of electrical current return paths vary during a treatment and wherein the switching of the first and second devices occurs independently of each other.

4. A method of providing electro stimulation to a subject including the steps of:
-
(a) attaching a plurality of electro stimulation probes in electrical connection with the subject;
(b) selecting one or more of the probes for connection to at least one electrical power supply thereby causing said one or more probes to become active probes;
(c) selecting one or more of the probes for connection to an electrical current return path thereby causing said one or more probes to become return probes;
(d) connecting said one or more active probes to the at least one electrical power supply and said one or more return probes to the electrical current return path thus causing an electrical current to flow between said active and return probes; and
(e) altering the selection of active and return probes; and
(f) repeating steps (d) and (e) until completion. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)

20. A method of controlling the supply of an electrical current to a subject connected to an electrical power supply unit that is in electrical connection with the an area of the subject by at least one active probe and return probe respectively including a first electrical resistance connected in parallel with the at least one active and return probe and having a controllable variable conductance network connected between the junction of the return probe and the first resistance and a ground reference, the method including the following steps:
-
initially controlling the variable conductance network to present a significantly low conductance such that limited current can flow through the area of the subject; and
subsequently controlling the variable conductance of the network to cause a desired electrical current flow through the area of the subject.
