Low Level Laser Therapy's Effect On Migration Of Human Skin Cells Across A Standardized Wound

Context: Low Level Laser Therapy (LLLT) is a newly utilized therapeutic modality in the treatment of injury. Authors have studied the macroscopic effects of LLLT on wounds in with mixed results. Objective: To measure the microscopic effects of LLLT on the repair of a standardized wound in human skin cells. Conclusions: These findings appear to be inconsistent with previous published research on wounds. Even though we observed a significance for time, the LLLT dosage did not alter wound healing. Our results imply that in small skin wounds there does not appear to be any benefit to the use of LLLT. This may be inconsistent with the use of LLLT for full thickness wounds of the skin in an athlete as noted in published macroscopic level studies.
