Abstract
A method for treating complex regional pain syndromes by applying an oscillating electric field to appropriate sympathetic ganglia. The method includes the steps of inserting an electrode into the vicinity of the sympathetic ganglion, for example the stellate and upper thoracic ganglia, such that the necessary electric field may be applied to the ganglion. The necessary field oscillation frequency and strength, as well as other characteristics of the signal are determined individually for each patient. Continued driving of the pathological activity of the ganglion into the normal function is the long-term, reversible palatative remedy for the condition.
