Abstract

A method for stimulating abdominal muscles of a subject, comprising the steps of providing at least three electrodes, one of the at least three electrodes being a central electrode and the other two of the at least three electrodes being side electrodes located on the subject spaced apart from the central electrode on respective sides thereof, and passing at least one pulsed signal subcutaneously through the subject between selected electrodes of the at least three electrodes.

Claims

1. A method for stimulating abdominal muscles of a subject, comprising the steps of:

providing at least three electrodes, one of the at least three electrodes being a central electrode and locating the central electrode adjacent to an umbilicus of a subject, the other two of the at least three electrodes being side electrodes and locating the other two electrodes on the right and left sides of the subject and spaced apart from the central electrode on respective sides thereof; and

passing at least one pulsed signal subcutaneously through the subject between selected electrodes of the at least three electrodes.

2. The method of claim 1, further comprising the step of selecting at least one pair of the at least three electrodes for applying the pulse so that the at least one pulsed signal passes subcutaneously through the subject between the at least one selected pair of the at least three electrodes.

3. The method as claimed in claim 2, wherein a plurality of pairs of electrodes are selected and further comprises applying the pulses simultaneously to each of the selected pairs of electrodes.

4. The method as claimed in claim 2, wherein a plurality of pairs of electrodes are selected and further comprises applying the pulses sequentially to each of the selected pairs of electrodes.

5. The method as claimed in claim 2, wherein one of the selected pairs of electrodes comprises one side electrode and the central electrode, and another selected pair of electrodes comprises the other side electrode and the central electrode.

6. The method as claimed in claim 2, wherein one of the selected pairs of electrodes comprises the two side electrodes.

7. The method as claimed in claim 2, wherein one of the selected pairs of electrodes comprises one of the side electrodes and one of a pair of first and second central electrodes making up the central electrode, and another of the selected pairs comprises the other of the side electrodes and the other of the pair of first and second central electrodes making up the central electrode.

8. The method as claimed in claim 7, wherein one of the selected pairs of electrodes comprises the first and second central electrodes which act as one single electrode and one of the side electrodes, and another of the selected pairs of electrodes comprises the first and second central electrodes which act as one single electrode and the other side electrode.

9. The method as claimed in claim 7, wherein one of the selected pairs of electrodes comprises the first and second central electrodes.

10. The method as claimed in claim 2, wherein a plurality of pairs of electrodes are selected and further comprises applying pulses to the respective pairs of electrodes that are the same or different.

11. The method as claimed in claim 1, wherein the step of passing at least one pulsed signal subcutaneously through the subject comprises applying a plurality of pulses at intervals in the range of 5 milliseconds to 1000 milliseconds.

12. The method as claimed in claim 11, wherein the step of passing at least one pulsed signal subcutaneously through the subject comprises applying a plurality of pulses at intervals in the range of 20 milliseconds to 40 milliseconds.

13. The method as claimed in claim 12, wherein the step of passing at least one pulsed signal subcutaneously through the subject comprises applying a plurality of pulses at intervals of approximately 24 milliseconds to 36 milliseconds.

14. The method as claimed claim 1, further comprises adjusting the interval between pulses of each pulsed signal.

15. The method as claimed in claim 1, wherein the step of passing at least one pulsed signal subcutaneously through the subject comprises applying pulses of duration in the range of 10 microseconds to 200000 microseconds.

16. The method as claimed in claim 15, wherein the step of passing at least one pulsed signal subcutaneously through the subject comprises applying pulses of duration in the range of 50 microseconds to 1000 microseconds.

17. The method as claimed in claim 16, wherein the step of passing at least one pulsed signal subcutaneously through the subject comprises applying pulses of duration in the range of 100 microseconds to 500 microseconds.

18. The method as claimed in claim 17, wherein the step of passing at least one pulsed signal subcutaneously through the subject comprises applying pulses of duration of approximately 240 microseconds to 360 microseconds.

19. The method as claimed in claim 1, further comprises adjusting the duration of each pulsed signal.

20. The method as claimed in claim 1, wherein the step of passing at least one pulsed signal subcutaneously through the subject comprises applying a plurality of pulses of magnitude in the range of 0 mA to 100 mA.

21. The method as claimed in claim 1, further comprising adjusting the magnitude of each pulse of each pulsed signal.
