“…An electro biofeedback device termed the Fenzian system (Fenzian Ltd, Hungerford, UK), where its waveform was deciphered and shown to resemble degenerate waves, has been used successfully in the treatment of symptoms in keloid and hypertrophic scarring and in accelerating the process of acute wound healing in the skin [ 34 , 47 , 48 , 82 ]. It is a transcutaneous low intensity device, which detects changes in skin impedance.…”

“…This device forms part of an electrobiofeedback link with the individual’s normal physiological repair. This modality follows the theory that the normal electrical potential of skin forms a global electrical network reflecting the underlying neurological activity through changes in skin impedance [ 82 ]. Using a concentric electrode the device detects the skin’s electrical impedance and adjusts the outgoing microcurrent electrical biofeedback impulses [ 82 ].…”

Electrical Stimulation and Cutaneous Wound Healing: A Review of Clinical Evidence

2014

Electrical stimulation (ES) has been shown to have beneficial effects in wound healing. It is important to assess the effects of ES on cutaneous wound healing in order to ensure optimization for clinical practice. Several different applications as well as modalities of ES have been described, including direct current (DC), alternating current (AC), high-voltage pulsed current (HVPC), low-intensity direct current (LIDC) and electrobiofeedback ES. However, no one method has been advocated as the most optimal for the treatment of cutaneous wound healing. Therefore, this review aims to examine the level of evidence (LOE) for the application of different types of ES to enhance cutaneous wound healing in the skin. An extensive search was conducted to identify relevant clinical studies utilising ES for cutaneous wound healing since 1980 using PubMed, Medline and EMBASE. A total of 48 studies were evaluated and assigned LOE. All types of ES demonstrated positive effects on cutaneous wound healing in the majority of studies. However, the reported studies demonstrate contrasting differences in the parameters and types of ES application, leading to an inability to generate sufficient evidence to support any one standard therapeutic approach. Despite variations in the type of current, duration, and dosing of ES, the majority of studies showed a significant improvement in wound area reduction or accelerated wound healing compared to the standard of care or sham therapy as well as improved local perfusion. The limited number of LOE-1 trials for investigating the effects of ES in wound healing make critical evaluation and assessment somewhat difficult. Further, better-designed clinical trials are needed to improve our understanding of the optimal dosing, timing and type of ES to be used.

Recent studies highlighted the beneficial effects of a novel electrical stimulation waveform, the degenerate wave (DW), on skin fibroblasts and symptomatic skin scarring. However, no study to date has investigated the role of DW on acute cutaneous wounds. Therefore, we evaluated this in a trial using a temporal punch biopsy model. Twenty healthy volunteers had a biopsy performed on day 0 (left arm) and day 14 (right arm). On day 14, DW was applied. Participants were randomised into two groups. Objective non-invasive assessments were performed on days 0, 7, 14, 60 and 90 using spectrophotometric intracutaneous analysis and full-field laser perfusion imaging. There were statistically significant increases in mean flux on day 14 (P = 0.027) in the post-DW arm. Haemoglobin levels increased on day 7 for the post-DW arm compared to without DW (P = 0.088). Differences in melanin levels were higher post-DW on the left arm between randomised groups on day 90 (P = 0.033). Haemoglobin levels in the vascular ring increased significantly from day 7 to 90 (P < 0.001 for post-DW and without DW arms). This study, for the first time, shows that DW increases blood flow and haemoglobin levels in acute healing wounds without affecting wound closure time and may have potential application in enhancing acute cutaneous healing.

Major advances have been made in the development of new therapies for chronic wounds. Fenzian™, an electrostimulation system (ES), has been clinically used for a variety of conditions. The ES was recently tested in the Barbadian population for tolerability and acceptability by asthma patients, with encouraging results. Barbados has an estimated 170 people with diabetes having some form of lower-extremity amputation annually. Here, we describe a case series of 21 chronic ulcer patients with diabetes recruited as inpatients (n = 10) and outpatients (n = 11) in a pilot study to evaluate the feasibility and acceptability of ES in the Barbadian population. Results showed statistically significant improvement among those in the inpatient- versus outpatient-recruited group for wound perimeter (P = 0·04), wound surface area (P = 0·03) and wound volume (P = 0·08). We also demonstrate that the improvement continued after cessation of ES treatment. Participants reported increased levels of pain at the end of treatment, and there was no statistically significant change in the reported quality of life. Our results showed greater improvements in reduction of ulcer size for participants from the inpatient- versus outpatient-recruited group.
