摘要：
目标： 低级激光治疗（LLLT）在过去几年中已使用用于治疗运动伤害。 The purpose of this study was to compare three therapeutic protocols in treating edema in second degree ankle sprains that did not require immobilization with a splint, under placebo-controlled conditions.
MATERIALS AND METHODS: Forty-seven soccer players with second degree ankle sprains, selected at random, were divided into the following组：第一组（n = 16）用常规初始处理（大米，休息，冰，压缩，抬高），第二组（n = 16）用大米方法加安慰剂激光处理，第三组（n = 15）用大米方法加上820 nm GaA1AS Diode激光器，其辐射功率输出为40 mW，为16 Hz。 Before the treatment, and 24, 48, and 72 h later, the volume of the edema was measured.
RESULTS: A three by three repeated measures ANOVA with a follow up post hoc test revealed that the group treated with the RICE and an 820-nm GaA1As diode laser presented a statistically significant reduction in the volume of the edema after 24 h (40.3 +/- 2.4 mL, p<0.01), 48 h (56.4 +/- 3.1 mL, p<0.002), and 72 h (65.1 +/- 4.4 mL, p<0.001).
CONCLUSIONS: LLLT combined with RICE可以减少二级脚踝扭伤的水肿。
