The aim of this study was to determine the effect of bipolar electroacupuncture (EA) on a soft tissue defect in rabbits. Ten clinically healthy New Zealand white rabbits were divided into two groups: the control group (Group C, n = 5) and the experimental (EA) group (Group T, n = 5). During neuroleptanalgesia, defects of soft tissue (skin and muscle) were made at the dorsum site on the rabbits in both groups, and those defects were stimulated using EA. The biopsy samples were collected on Day 2, Day 4, and Day 6, prepared for histology, and examined microscopically. On the 2(nd) day, in Group C, the inflammatory degree was higher than it was in Group T; on subsequent days, low or identical degrees of inflammation were observed in both groups. Proliferative fibrous activity was increased on Day 4 for Group T and identical for both groups on Day 6. The dynamics of the epidermal thickness were characterized by a high rate on Day 2, Day 4, and Day 6 for Group T. EA facilitates a low tissue mechanical stress and has a positive effect on the healing of muscular defects. EA enhances the healing process, with no side effects.
