This study aimed to evaluate the effect of microcurrent electrical stimulation on pain and area of venous ulcers. In a pilot study for a single-blind controlled clinical trial, carried out at an outpatient clinic during four weeks, 14 subjects with venous ulcers (mean age 62±9 years) were divided in two groups: microcurrent (n=8) and control group (n=6). Pain (by Visual Analogue Scale) and the ulcer area were measured by planimetry. There was a significant difference between the two groups with respect to pain (microcurrent group from 8.5 (6.5-9.75) to 3.5 (1-4.75) and control group from 7.5 (5.75-10) to 8.5 (5.5-10), p<0.01). Non-significant changes were found with respect to ulcer area (planimetry by graph paper, p=0.41 and by Image J®, p=0.41). In conclusion, the application of microcurrent improves the pain of patients with venous ulcers (ClinicalTrials.gov: NCT01372020).
