Electric sympathetic block:  methods of measurement and a study assessing its effectiveness.
Electric sympathetic block is the procedure whereby sympathetic nerve fibers are blocked by application of controlled electrical impulses via electrodes placed on the skin.  Methods of measuring the extent of sympathetic blockade and a clinical study using bipolar middle frequency currents to achieve electric sympathetic block are presented.  Fifteen of 20 (75%) patients who underwent a 1-week series of electric sympathetic blocks reported at least 75% subjective relief from sympathetically mediated pain after completion of the series.
