The polarity effect of electrical stimulation on wound healing is a continuing challenge in rehabilitation. Despite some recent advances in our understanding of wound healing and its basic principles, many problems in treatment exist, especially for chronic wounds. We studied how daily 1-hour anodal versus cathodal pulsed electrical stimulation for 14 or 21 days affected wound healing in guinea pigs. Our results suggest that electrical stimulation, regardless of polarity regimen, benefits wound healing, but anodal stimulation the first 3 days and cathodal stimulation the remaining days can strengthen repaired tissue.
