Intervention 1: In the electrical stimulation group, an active carbon rubberized electrode (3 × 4 cm) was placed just outside the ulcer surface area. A dispersive electrode (4 × 6 cm) was placed approximately 20 cm proximal to the active electrode and far from the wound on the proximal region of the leg. The polarity of the active electrode was negative (cathode) during the treatment period. Cathodal direct current with sensory threshold intensity applied to the wound site for 1 h/day, 3 days/week and for 12 sessions. Intervention 2: In placebo group, an active carbon rubberized electrode (3 × 4 cm) was placed just outside the ulcer surface area. A dispersive electrode (4 × 6 cm) was placed approximately 20 cm proximal to the active electrode and far from the wound on the proximal region of the leg. In the placebo group, the treatment procedure was the same as that described for the electrical stimulation group, but the current intensity was zero.
