Effects of concurrent optical and magnetic stimulation in hard-to-heal wounds: a real-world evidence case series.

Objective: This work explores concurrent optical and magnetic stimulation (COMS) effects on hard-to-heal wounds in real-world settings.

Method: In this case series, participants received COMS 1-3 times per week for up to 12 weeks alongside standard wound care.

Results: A total of 27 patients (18 female and nine male) were included. Mean age was 72 years. Participants' wounds that were unresponsive to standard wound care included: venous leg ulcers (VLUs, n=13); mixed leg ulcers (MLUs, n=4); diabetic foot ulcers (DFUs, n=1); pressure ulcers (PUs, n=5); and traumatic wounds (TWs, n=4). On average, COMS was applied twice a week, resulting in an overall mean wound area reduction of 69%. In 24 participants, COMS was used primarily to achieve wound closure by the end of the 12-week period, of which: 12 were classified as complete wound closure (50%; VLUs=8, PUs=3 and TW=1); four as likely-to-heal (17%; VLUs=2 and MLUs=2); four as 'improved' (17%; MLU=1, DFU=1 and TWs=2); and four as 'non-responding' (17%; VLUs=3 and MLU=1). The best results were achieved in PUs and VLUs (respectively 100% and 62% categorised as completely healed). When used in participants where its purpose was other than that of achieving wound closure, COMS was successfully used to debride two PUs, and for wound bed preparation in one TW.

Conclusion: In this case series, COMS showed positive effects and appeared to be beneficial in healing different types of hard-to-heal wounds in community health and homecare settings. Novel COMS therapy aspects emerged: (1) positive outcomes for PU and VLU treatment; (2) COMS as a potential debridement tool when sharp debridement is unfeasible; and (3) COMS as a promising method to prepare wound beds for subsequent skin grafting or skin replacement procedures.
