Effectiveness of Microcurrents Therapy in Pressure Ulcers in Elderly People

"CARE NURSING PROTOCOL: postural treatment every 4 hours more standardized cure according to the guide of recommendations based on evidence in prevention and treatment of pressure ulcers in adults of Osakidetza health service.~MICROCURRENTS: the electrodes will be placed on the edge of the dressing on the sides of the ulcer's longer length during 12 hours a day until the ulcer is completely healed or for a maximum of 25 days.~Characteristics of microcurrents: pulsed monophasic rectangular wave with a pulse of 1.5 s and pause of 300 ms, voltage 21 mV and intensity 42μA with a current density of 4.2 μA."

The same nursing care protocol described for the experimental group will be applied more 12 hours per day of 2 electrodes of microcurrents around the ulcer, which will be previously manipulated and tested with an oscilloscope so that they do not emit electrical currents
