The study evaluates the efficacy of Low-level laser therapy on ulcer healing in patients with diabetic foot ulcer. Half the patients are randomized to receive Low-level laser therapy and a half to recieve the placebo (LED).

Low-level laser therapy(LLLT) has been reported to aid ulcer healing in patients with diabetic foot ulcer. However, patients need to come to hospital to receive LLLT performed by medical professional. The LLLT shoe has been developed for home using. Patients can wear LLLT shoe 30 min once daily instead of going hospital for LLT therapy. The aim of this study is to see whether LLLT shoe helps with healing compare with placebo (LED shoe).
