Use of photobiomodulation with blue light in the treatment of ulcers of various etiology in spinal cord injured patients: a case series

The case study sought to validate the efficacy of Photobiomodulation with Blue Light as a therapy for promoting the healing of skin lesions resistant to conventional therapies in patients with spinal cord injuries. 25 patients were treated for a total of 32 skin lesions of various etiologies, primarily 2nd, 3rd, or 4th-degree pressure ulcers (ref. EPUAP/NPUAP classification), that had been present for more than 90 days and showed no clinical signs of evolution toward healing, despite having already received advanced medication treatment in the Spinal Unit for more than 4 weeks. For photobiomodulation therapy, a class IIa medical device (EmoLED) was employed, which uses LED sources that generate blue light in the 410-430nm region. Blue Light treatment restarted the healing process in 68.7% of the ulcers treated, with an average level of re-epithelialization of 72.8%. Blue Light, based on our prior experience, is a therapy that can assist shorten treatment and hospitalization times while also improving patients' quality of life; it can also be utilized for frail patients because it is well tolerated and readily deployed.
