Claim 0:
1. An apparatus configured for therapeutic electrical stimulation of a patient, the apparatus comprising:
an electrode carrier configured to place a set of electrodes into contact with an external part of the body of the patient on the external part of the body of the patient, the set of electrodes containing at least three electrodes; and
a stimulation module comprising:
signal generation circuitry configured to generate an electrical stimulation signal as a Direct Current (DC) pulse train at a frequency of between 10 kHz and 50 kHz; and
control circuitry that is configured to sequentially activate individual subsets of the electrodes contained in the set of electrodes, the individual subsets comprising at least a first subset and a second subset, and wherein each subset contains a unique combination of at least two of the electrodes contained in the set of electrodes, with at least one electrode contained in each subset activated as a signal source for the electrical stimulation signal and at least one other electrode contained in each subset activated as a signal sink for the electrical stimulation signal.
