由于传统方法在脑疾病治疗方面的局限性, 低照度光疗法越来越受到重视。低照度光疗法利用波长在600 nm-1 100 nm的低功率激光或者准单色光以非破坏和非热行为来调制生物过程, 用于促进伤口愈合, 抑制感染、水肿以及减轻疼痛等。近来, 研究者进行了大量低照度光治疗脑损伤疾病方面的实验, 研究对象从细胞、动物模型到人类, 病症从卒中, 急性脑创伤到慢性脑损伤以及神经退行性病变等。研究结果表明, 低照度光疗法有可能应用于脑部损伤疾病的治疗。介绍了低照度光疗法的机理、应用, 并对低照度光疗法的治疗参数, 包括治疗窗口、波长以及剂量等进行了回顾。

Low level light therapy is a steady developing therapeutic approach to treat brain damage diseases due to the limits of traditional method.It is using low power laser or quasi-monochromatic light with the wavelength from 600nm to 1100nm to modulate biological function in a nondestructive and non-thermal manner.It has been used for wound healing, pain relief, treatment of inflammation and swelling.And recently, it has been explored for treatment of brain damage diseases. The mechanism, applications and therapeutic parameters of low level light were reviewed.
