    Abstract: An electrical apparatus applies an electric field, e.g. a r.f. field, in a timed manner such that over a given cycle period, e.g. 24 hours, the field is applied for a selected portion of the cycle period and is switched off for the remainder of the period. The periods may be programmable utilizing a microprocessor. The field strength may be selected so as not to produce significant tissue heating, typically less than approximately 100 .mu.w/cm.sup.2, measured at a system surface.
