Abstract

Fortyeight patients with knee OA were randomly allocated to two groups 24 per group receiving 20 min irradiation with 650 nm 106 μm combined laser or red light emitting diode respectively on point Dubi ST 35 3 times a week for the first course 2 weeks and twice a week for the second one 4 weeks The main outcome measures were WOMAC Western Ontario and McMaster Universities Osteoarthritis Index scores In addition patients’ global assessment adverse effects and validation of patient blinding were analyzedAll the patients completed the first course but 12 were lost during the second one Due to the high dropout rate by the second course only the data acquired from the first course could be analyzed No differences of general data of patients and WOMAC scores were found in betweengroup comparison before treatment P005 The WOMAC scores of patients in both combined laser group and red light group reduced significantly compared to baseline by the end of the first course P001 There were no significant differences on the reduction rate of WOMAC scores between two groups P005 Neither the patients’ global assessment nor the dropout rate showed statistical differences between two groups P005 There was no difference between two groups in patients correctly guessing the treatment assignment P005 There was no significant difference in the reduction rate of WOMAC scores and the patients’ global assessment between patients who guessed their assignment P005 Conclusion Both combined laser and red light irradiation are beneficial to patients with knee OA But as the statistical indifferences between two groups the authors can’t conclude from this study whether the combined laser is more effectiveFund Items the Science Foundation of Shanghai Municipal Commission of Science and Technology 05DZ19745 06DZ19732 064319053 07DZ19722 07DZ19733 the National Basic Research Program of China 973 Program 2005CB523306 National Natural Science Foundation of China 30572306 Shanghai Leading Academic Discipline Project B112 and T0302所有患者均完成了第一疗程 但有12 名患者在第二疗程脱落。 由于第二疗程的脱落率较高 故只对第一疗程的数据进行分析。 治疗前 两组患者一般情况及WOMAC得分无显著性差异P005。 治疗后 复合激光组及红光照射组患者WOMAC得分与基线期相比均有显著降低P001。 两组患者WOMAC得分改善率比较无显著性差异P005。 两组患者对疗效的自评及脱落率比较均无统计 学差异P005。 两组患者对自己所属分组的猜测无统计学差异P005 且两组患者对自己所属分组的猜测未对其WOMAC得分改善率及对疗效的自评产生影响P005。
