Abstract :
Introuduction: Low level laser therapy (LLLT) is gaining acceptance in clinicalapplications. For example, it is used as therapeutic modality in the repair of diabeticfoot ulcer when conventional therapy was not effective, separately. The aim of thisstudy is to determine the effect of local and intravenous LLLT for the healing ofdiabetic foot ulcer.
Material & Methods: This study contains 74 diabetic foot-ulcers which were proneto resistance to conventional therapy. Different stages of diabetic foot are includedin this study. The wounds irradiation are performed by the combination therapy of650 nm and 860 nm laser, with the total energy density of 3.6 J/cm² plus intravenouslaser therapy (IVL) with 2.5 MW, 650 nm laser used for 30 minutes. All woundshave been photographed from equal distance, before and after treatments, and allthe wounds were staged by a surgeon who was disinterested and neutral about theeffects of the laser therapy. Her judgments were based on the visual assessments ofthe wounds. All the mathematical and statistical analysis is based on the descriptivestatistics which, is done by the SPSS 16.
Results: in the result of this study; 62.2% (Forty-six out of the 74 ulcers) completelyhealed, 12.2% (Nine in numbers) healed more than 50%, 8.1% (Six in numbers) healedless than 50%, 5.4% (Four in numbers) not healed,12.2% (Nine in numbers) didnot continue their treatment (less than 5 sessions of Laser therapy). Excluding, thewounds in stage 5, more than 80% of each stage’s wound, completely healed morethan 50%, with in 2 months duration. In this study, we definitely can express that, allthe Patients received some degrees of healing, during their laser receiving treatments.
Conclusion: The combined local and intravenous LLLT promote the tissue repairprocess of diabetic foot ulcer. In this multi-disciplinary method, we achieved aremarkably shorter mean healing time of two months, compared with other reportedstudies with healing time of three to six months
