Clinical Trial Summary

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.

Description:

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.

Intervention

Device:
• B-Cure Laser Pro
The B-Cure Laser Pro is a portal, non-invasive low-level laser therapy device, that emits light in the near infrared (808nm) over an area of 1X4.5 cm2 with power output of 250mW, and energy dose of 5J/min
• Sham laser
The sham laser device is externally identical to the B-Cure Laser Pro and emit the same guiding light, but does not emit the therapeutic near infrared rays
