Abstract

Background: Diabetic foot ulcer is a problem in patients with diabetes mellitus (DM). One adjuvant therapy that can enhance wound healing is Low-Level Laser Therapy (LLLT), but there is no established guideline regarding the dosage. In Indonesia, there has been no study comparing the energy density of LLLT on diabetic ulcer healing
Methods: This is an experimental study on 28 subjects with a randomized diabetic foot ulcer. Group A received standard treatment of ulcer and LLLT 5J/cm2. Group B received standard treatment of ulcer and LLLT 10J/cm2.
Results: The difference in wound size between group A and group B were 4.15 mm2 and 7.5 mm2 (p=0.178). The healing rate of group A and group B were 4.15 (-10-34.5) mm2/4 weeks and 7.5 (-2.8-34) mm2/4weeks (p=0.168).
Conclusions: There was no statistically significant difference between the group receiving LLLT 5J/cm2 or 10 J/cm2 in diabetic foot ulcer healing.
