METHODS: Forty-one cases with knee OA of yang deficiency and cold coagulation type were randomly divided into a combined laser group (n = 22) and a red light group (n = 19), with combined laser and red light irradiation on Dubi (ST 35) and Neixiyan (EX-LE 4), respectively. They were treated for 6 weeks. The scores of Western Ontario and McMaster Universities' Osteoarthritis Index (WOMAC VA3. 1) were used for assessment of therapeutic effects. RESULTS: After treatment for 2 weeks and 6 weeks, the WOMAC scores significantly decreased in the two groups as compared with those before treatment (P < 0.05, P < 0.01 and P < 0.001). The mean improvement rate of WOMAC scores in the combined laser group was better than those in the red light group. CONCLUSION: Combined laser irradiation can improve the pain, stiffness and functional limitation of patients with knee OA of yang deficiency and cold coagulation type. PMID: 21290832
