1. A neuromodulation apparatus for a medical treatment comprising:
a plurality of active electrodes electrically isolated from each other and arranged in at least one electrodes array, wherein each active electrode comprises an electrically conductive element configured to be applied to a skin of a patient;
at least one reference electrode configured to be applied to the skin of the patient;
a pulse generator electrically connected to each active electrode of the plurality of active electrodes and configured to selectively transmit electric pulses for the neuromodulation medical treatment to each of the plurality of active electrodes;
a control unit coupled to the electrical pulse generator and adapted to measure a resistance and/or a current-voltage characteristic between each active electrode of the plurality of active electrodes and the at least one reference electrode, wherein based on the measured resistance and/or current-voltage characteristic the control unit is adapted to both control a shape of the electrical pulses and select which an active electrode or active electrodes of the plurality of active electrodes are to receive the electrical pulses for the neuromodulation medical treatment generated by the pulse generator,
wherein the control unit is further configured to determine a current density of electrical pulses for the neuromodulation medical treatment flowing through each of selected active electrodes during the neuromodulation medical treatment and based on the result selectively employ active electrodes neighboring to the each of the selected active electrodes within the same electrodes array to also receive electrical pulses for the neuromodulation medical treatment generated by the pulse generator.
