Abstract

Abstract Introduction: We developed and tested a new system for inducing the healing of diabetic foot ulcers. The system relies on the regenerative properties of its two components: an insole with a sheet of natural latex and a device that contains a matrix of light emitting diodes with wavelength of 635 nm. Methods: The electronic and latex based devices were developed, and a four weeks test was performed in one control group (CG) of five ulcers and one experimental group (EG) of eight ulcers. The CG was treated with a standard approach, based on a silver-releasing foam dressing, and the EG was treated with the system under test. For each ulcer, an index for quantifying the percentage ulcer recovery, named CRU(%), has been calculated; a CRU(%) = 0% means no healing, and a CRU(%) = 100% means total healing. Results: There were statistically significant increases of CRU(%) of 51.8% (p = 0.022), for the CG, and of 78.4% (p < 0.001), for the EG. The increase in the EG was higher than the increase in the CG, and the difference was statistically significant (p < 0.001). The results showed that the proposed method had, for these particular sets of ulcers, faster healing rates, than for the standard method. Conclusion: The results hint that the proposed method seems promising as a future treatment method. However, the technique must undergo further testing before it can be considered for extensive clinical applications.
