Three separate pairs of electrodes are attached to a body part to be treated, spaced apart around said part of the body. A primary alternating electrical current having a primary frequency of between 100 Hz and 100,000 Hz is passed between one of the electrode pairs. A similar second alternating electrical current having a secondary frequency in the same range as the primary frequency but differing by between 50 Hz and 100 Hz from the primary frequency is passed between another of the pairs of electrodes. A tertiary alternating current is passed between the third pair of electrodes and has a tertiary frequency differing by at most 1 Hz from the frequency of either the primary current, the secondary current, or the arithmetic means of the frequency of these two currents.
