Laser Therapy for At-Home Treatment of DIabetic Foot Ulcers

The global prevalence of diabetes is on the rise and with it increase in prevalence of diabetic foot ulcers (DFU). These recalcitrant wounds are difficult to manage and pose a heavy economic burden. Photobiomodulation (low-level laser) is used for acceleration of wound healing.

The current study is designed to evaluate the effectiveness of B-cure laser, a home-use low-level laser device, for acceleration of diabetic foot ulcer healing over standard treatment.

Patients with diabetic foot ulcers will receive standard treatment and in addition will be randomly allocated to receive either active or sham laser device to self-treat at home. The patient's wound will be evaluated every 2 weeks. Adverse events will be documented.

The study hypothesis is that B-Cure laser treatments as an adjunct therapy to standard treatment, applied, at home, by the patient or personal care-giver, can accelerate diabetic foot ulcers healing compared to standard treatment alone.
