Apparatus and method for controlling the application of therapeutic direct current to living tissue

摘要

Apparatus and a method for applying current of a particular form to bulk resistance means such a living tissue. The applied current is D.C. at a level so low as to generate voltage gradients within the bulk resistance such as to be substantially under nerve or muscle stimulation potential. Apparatus is provided to increase the current level at a first predetermined rate to a first level for a first period of time, to lower it to a second level for a longer period of time, then to lower it to zero at a second predetermined rate. When applied to painful living tissue substantial reduction or elimination of pain and inflamation has been found to occur.
