Objective: To evaluate the effect of non-invasive biofeedback electrical stimulation on symptomatic abnormal skin scars. Method: Thirty patients with over 140 scars with long-term pain and itch were recruited into the study. Patients monitored the intensity of symptoms (pain and itching) on a numerical rating scale. In addition, a modified Manchester scar scale was used to objectively assess digital photographs of each scar in terms of colour, contour, distortion and texture, while a non-invasive spectrophotometric intracutaneous analysis was used to monitor the scars' physical characteristics. Results: The electrical stimulation device resulted in a clinically and statistically significant (p<0.05) reduction of symptoms and scar scores. Pain and itch scores were both reduced to a median score of 0 by 2 months, from a baseline of 7 and 6 respectively. Scar scores were reduced from a baseline of 14 to a median score of 11 by 2 months. Conclusion: These results give a preliminary indication of the potential role of non-invasive biofeedback electrical stimulation in the management of chronic scar pain and itch. However, further large scale controlled studies are warranted to elucidate its overall efficacy and mechanistic action.
