Laser Therapy for At-Home Treatment of Diabetic Foot Ulcers - Canada

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.
