Maintain the action ofthe current for about ten minutes and reduce to zero. Thismethod gives great relief when pain is due to intense conges-tion or the pressure of fluids. The positive current drivessome of the fluids away and relieves the tension of the skin. In the case of large joints a large positive electrode can befastened around the part with the negative at any convenient. Fig. 365.

In recent jointexudations the action of the positive galvanic current relievesthe pain and stiffness, increases the mobility and accomplishesa great deal of good. When the case is chronic the active electrode should be thenegative, and after reducing the constant current to zero em-ploy the interrupted galvanic current for a few moments toaid in, dissipating the fluids released by electrolysis. While the galvanic current does important work in thetreatment of articular inflammatory exudations yet it is em-plo3^ed by only a few variations of method, so that not muchneed be said about it. The great majority of rheumaticpatients need something more than a strictly local applica
