To determine the effectiveness of Low-level laser therapy (LLLT) for grade 3 diabetic foot ulcer. To determine the size of the wound with acetate tracing after the application of Low-level laser therapy.40 subjects with grade 3 diabetic foot ulcers based on the inclusion and exclusion criteria were assessed these include subjects above the age of 35, ulcer without infections, ulcers grade 2 based on Waggner grading. The content of 40 participants, received low-level laser therapy for 4weeks, 6days/week. Outcome measures were taken at the baseline and after 4weeks of the treatment protocol. This research work states that LLLT (40.65 SD 13.5) showed significant improvement in wound contraction after pretest and posttest of treatment. Hence from the above results, it was proved that LLLT is more significant and effective method for grade 3 diabetic wound healing. From the effect, it has been concluded that LLLT is more effective in decreasing the healing time and improving the quality of life.
