If the directions given so far have allowed the reader to establish the cause of some segmental pain, the somatic or sympathetic nerve should be known. It then becomes necessary to place the anode over this nerve to treat the pain. In conditions where such segmental allocation is impossible (e.g. joint pain), it is advisable to select an impulse with a higher DC-component whenever the apparatus provides such modalities of current. If this is not possible, the duration of a single pulse should be doubled. Keep the size of electrodes as different as for treating nerves and use the small electrode as the anode over the most painful area (e.g. in gonarthrosis, figs. 93 and 94). The duration of the therapeutic session should be 20 minutes. This subtle difference in type of current should be noted also when regarding table 6. Higher DC-component is equal to the FM- selection on some apparatus (e.g. Electroblock, Relaxette; see table 2).
