Relevance – Diabetic foot ulceration is a significant complication of diabetes. – Evidence exists that expression of growth factors like VEGF may reduce its occurrence.

Treatment (random assignment): – Electrical stimulation (ES) (n = 10). Cathodal direct current 1 h/d, 3 d/wk for 4 wk (12 sessions). – Sham ES (placebo, n = 10). Measures: – VEGF and NO (blood samples) at 1 st and 12 th sessions before and after intervention. – Wound surface area and skin temperature at 1 st, 6 th, and 12 th sessions.

NO: – Significantly increased in ES compared with sham ES after 12th session. Skin temperature: – Significantly higher increase in ES than sham ES.
