Efficacy of low-level laser therapy on wound healing in human subjects: a systematic review

摘要: . This systematic review summarises the efficacy of infrared low-level laser therapy (LLLT) on wound healing in human subjects. In order to retrieve randomised clinical trials, we performed computer-aided searches databases and bibliographic indexes. Furthermore, congress reports, reviews handbooks were checked for relevant citations. Subsequently, all retrieved masked studies scored methodological quality. We found four trials that investigated effects LLLT versus placebo or any other intervention. Only one trial demonstrated a beneficial effect. Overall, study quality ranged from poor insufficient. For three could perform meta-analysis. The overall effect size estimate indicates had no significant (pooled RR=0.76, 95% CL 0.41–1.40). conclude there are scientific arguments routine application (904 nm) patients with decubitus ulcers, venous leg ulcers (ulcus cruris) chronic wounds.
