Treatment of symptomatic abnormal skin scars with electrical stimulation

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
