In a double-blind comparison of magnet patches versus sham patches (10 patients per group), the treatment group had significant reductions in pain (postoperative days 1–7), edema (days 1–4), and discoloration/ecchymosis (days 1–3) compared with controls.

Abstract

The authors present their experience with the healing influence of permanent magnets on postoperative wounds. The responses of 20 patients who underwent suction lipectomy and postoperative negative magnetic field therapy were studied in a double-blind fashion. Magnets in the form of patches (10 patients) or sham magnet patches (10 patients) were placed over the operative region in each of the patients. Pain, edema, and discoloration (ecchymosis) were evaluated at 1, 2, 3, 4, 7, and 14 days postoperatively. Our results show that the treatment group had significant reductions in pain on postoperative days 1 through 7, in edema on days 1 through 4, and in discoloration on days 1 through 3 when compared with the control group. These results demonstrated that commercially available magnets have a positive influence on the postoperative healing process in suction lipectomy patients.
