Materials and methods: A pilot study was conducted in 14 patients (age 30.9±7.5 years) with second- and third-degree burns of different types. The burn types included electrical, fire/flame, and chemical. All patients received continuous and intermittent electrical transcutaneous nerve stimulation sessions three times per week for 4 weeks. Each session had a duration of 30 minutes. A pair of electrodes were placed around the burn. The primary efficacy endpoint was the perception of pain assessed by a visual analog scale at baseline and at the 30th day. Results: A significant reduction of pain perception was reported (8.0±1.7 vs 1.0±0.5; P=0.027) by all patients after electrical stimulation therapy. There were no reports of adverse events during the intervention period. Conclusion: Electrical stimulation could be a potential nonpharmacological therapeutic option for pain management in burn patients. Keywords: TENS, burn pain, pain management, electrotherapy
