Study Groups

HVG
The patients received standard nursing care and HVPC
High voltage pulsed current
The patient´s wounds were treated for 45 minutes with HVPC three times a week for 16 weeks or until their ulcers closed. The active electrode made of aluminum foil was secured directly over the wound, which previously had been loosely packed with sterile gauze soaked with 0.9% saline solution. The dispersive electrode was placed 5 cms proximal to the wound.The electrical stimulator Intelect 340 stim model (Chattanooga Group) produces a twin peaked pulse and was applied with the following parameters: continuous mode, submotor level, 100 Hz pulse frequency and 100microseconds pulse duration. Prior to the beginning the study the electrical stimulator was calibrated with oscilloscope (Tektronix TDS 1002 model).
LG
These patients received standard nursing care and LLLT
Low level laser
Wavelenght 633 nm (DMC - Brazil), power 30 mW, continuous, 2 J/cm2 in the edge of the ulcer and 1.5 J/cm2 in the bed, punctual application in direct contact, 3 times a week, 1 every alternate day, for 16 weeks or until the ulcer closed. The laser device was calibrated before each treatment session with a research radiometer (International Light).
CG
The control group only was treated with standard nursing care
Standard nursing care
It was based to nursing intervention classification (NIC)46. These interventions were performed by a qualified nurse and included ulcer irrigation with physiological saline, sharp debridement as needed and maintenance of a moist wound environment with appropriate wound dressing. Patients were all educated regarding pressure off loading of the involved foot. All patients received standard wound care seven times a week for 16 weeks or until their ulcers closed.
