Uniformly and consistently increases electrode to skin conductivity. PRINCIPLES OF APPLICATION

S-D curve should be plotted after 20th day of injury/lesion. So the main problem associated with low freq. This effectively limits the cross-sectional conductor area available to carry alternating electron flow, increasing the resistance of that conductor above what it . The ions are driven into the skin via the pores - hair follicles, sweat gland ducts - rather than through the stratum corneum per se (the stratum has a high resistance, thus limited current passes through it - the ducts are lower resistance, will allow greater passage of current, thus the route of preference).
