Abstract:
The aim of this study was to determine the efficacy of light-emitting diode
therapy in enhancement of chronic diabetic foot ulcer. Fifty patients participated in
the study. They suffered from chronic foot ulcer as a complication of diabetes
mellitus, their ages ranged from 50 to 70 years old. They classified into two equal
groups (LED therapy group and standard medical therapy group). LED group
received light – emitting diode therapy in addition to standard medical treatment for
thirty sessions., while standard medical group received standard medical treatment
only also for thirty sessions. Additionally two weeks period of follow up was added to
the total program. There was statistical significant reduction in wound surface area
after 15 and 30 sessions (P<0.05). There was also a statistical significant
improvement in the degree of healing rate in LED therapy group through
histopathological assessment of the tissue biopsy after 30 sessions. There were (16%)
with fair healing, (76%) with moderate healing (8%) with excellent healing. While, in
standard medical therapy group all patients (100%) were presented with poor
healing. Therefore, light-emitting diode therapy is an effective, innovative, non
expensive modality in the treatment of diabetic foot ulcer combined with standard
medical treatment.
