The promotional effect of low intensity direct current stimulationon pressure ulcer healing

The critical point of low intensity direct current (LIDC) intensity to facilitate the fibroblast migration to cathode was 200 μA. Condensed discharge was detected after electrical stimulation and the storage completed at three seconds after the beginning of electrical stimulation. This suggests the necessity of electrical shunt. LIDC (frequency; 2 Hz, pulse length; 250 ms, stimulation intensity; 80 μA, duration; 40 minutes) with cathode electrode placed on wound site and anode electrode placed on the skin around wound, contributed to pressure ulcer healing. This study is ongoing, andno adverse event has been observed in clinical study.
