Abstract

A method of treating a wound comprising the steps of placing a pair of electrodes placed spaced apart in the region of a wound and applying a predetermined sequence of current waveforms across the electrodes. The sequence of current waveforms comprises a first waveform comprising a series of current pulses having an amplitude in a range of from 80 to 300 μA, having a frequency in a range from 0.5 to 1.5 pulses per second and a pulse width in a range from 333 to 1000 ms, a second waveform comprising a series of current pulses having an amplitude in a range of from 20 to 60 μA, having a frequency in a range from 2 to 4 pulses per second and a pulse width in a range from 125 to 250 ms and a third waveform comprising a series of current pulses having an amplitude in a range of from 250 to 640 μA, having a frequency in a range of from 80 to 120 pulses per second and a pulse width in a range from 4 to 6 ms.
