Abstract: Objective: To examine the effects of pulsed electromagnetic field (PEMF) therapy on promoting the healing and microcirculation of chronic diabetic foot ulcers. Design: A randomized, double-blind, placebo-controlled clinical trial on a homogenous subset of chronic diabetic foot ulcers. Setting: Hospital and university. Patients: Thirteen subjects (7 in the PEMF group and 6 in the control group) diagnosed with type 2 diabetes and had unsatisfactory healing of ulcer(s) in the preceding 4 weeks were recruited. Interventions: Subjects were randomly allocated to receive either active Pemf therapy (duration: 60minutes; frequency: 12 Hz; intensity: 12 Gauss) or nonactive PEMF for 14 sessions within 3 weeks. Main Outcome Measures: Assessment on wound closure, wound depth, and microcirculation were performed at the baseline, end of the treatment period, and 1-month follow-up. Main Results: By the end of the treatment period, there was an 18% decrease in wound size in the active PEMF group as compared with a 10% decrease in the control group. The PEMF group demonstrated significant cumulative increase in cutaneous capillary blood velocity (by 28%) and 14% increase in capillary diameter. In contrast, the control group showed a decrease in both capillary blood velocity and diameter. Conclusion: In this study, PEMF therapy seemed to accelerate wound healing and improve microcirculation.
