Background: Across the globe, diabetes mellitus (DM) is considered as a major health issue because of its prevalence rate tending to increase day by day in a remarkable manner. A foot ulcer is frequently faced complication that is very frequently faced in patients suffering from diabetes mellitus. Diabetic Mellitus is noticed as a severe health issue affecting around 387 million people. The purpose of this study is to study the effect of low level laser therapy on diabetic foot ulcers to control infection, determine best suitable cost-effective technique and aid in studying the role of Low-level laser therapy in the context of treating diabetic foot ulcers. Aim: To study the role of low-level laser therapy on diabetic ulcers Results: The proportion of males was slightly higher than females in both cases and controls. The mean BMI was 26.50±2.444 among cases and mean BMI was 25.27±2.407 among controls. Among 16 grades 1 ulcer, 6 (37.5%) remained in grade 1, 10 (62.5%) ulcers completely healed at the end of 20 days. In group B, 21 subjects had bacterial growth on day-1, and the remaining 19 had no bacterial growth. Out of the 21 with bacterial growth, 15(71.42%) still had growth at the end of 20 days, and 6 (28.58%) had no growth. Methods: The current study was a randomized open labelled control study, with randomised two treatment groups [Group A: Intervention group (who received laser therapy in addition to standard management) Group B: Control group (standard treatment group)] and total sample size of 80 performed at the Department of Surgery, Banas Medical College and Research Institute, Palanpur, Gujarat between Jan-17 to Dec-17. Descriptive analysis was carried out by mean and standard deviation for quantitative variables, frequency and proportion for categorical variables. Data was also represented using appropriate diagrams like a bar diagram, pie diagram and box plots. The area of the ulcer was compared between the two groups, using independent sample t-test. The mean differences along with their 95% CI were presented. Association between quantitative explanatory and outcome variables was assessed by calculating the Pearson correlation coefficient and the data was represented with P-value. Conclusion: It can be concluded that Laser therapy is best-suited therapy for curing the diabetic foot ulcer as it is pain-free, effective on budget, wound contraction as well as re- epithelialisation helped in accelerating the curing of the wound with simple curing process following proper medication and instructions provided with laser therapy. Control of infection becomes easy as compared to any other techniques being used such as split skin grafting, and other secondary expensive procedures attempted to cure DFU.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
