BACKGROUND: Chronic venous leg ulcers are major health problems in most countries with patients who suffer from chronic venous insufficiency. LLLT is most commonly used physiotherapy modality used as a tissue stimulator to improve wound healing and they also have anti inflammatory and an analgesic effect. Very few studies attempted to find the efficacy of LLLT in the management of venous leg ulcers. Study Design: Pre and post with control group design. Materials and Methods: 40 patients who diagnosed with venous ulcers in the leg are randomly arranged and allocated equally to either experimental or control group. 20 patients of the experimental group was treated with Low Level Laser Therapy (wave length 904nm), Power 0.5 to 4 J/cm2 , Duration 2 min, along with routine medication and 20 patients of the control group were treated conservatively with routine medications. Both groups were treated 3 times a week for 4 weeks. The wound size is measured along grid system on the first day of treatment and at the end of four weeks for both the groups. Results: At the end of the four weeks both LLLT and control group showed improvements in venous ulcer healing. But intergroup comparison shows that LLLT group wound size was 60.36 cm2 before treatment and after treatment wound size was reduced to 46.71 cm2 and in conservative group wound size 63.34cm2 before the treatment and which has reduced only 62.07cm2 at the end of the four weeks of treatment. So the result showed that LLLT group shows statistically significant improvement results (P<0.005) in venous leg ulcer healing. Conclusion: From the results of the study we can conclude that Low Level Laser Therapy is an effective method of treatment for venous leg ulcer patients.
