Objective To observe the clinical efficacy of Huoxue Bitong Plaster on lumbar osteoarthritis with blood stasis and cold-dampness blocking collaterals syndrome. Methods Totally 120 patients were randomly divided into treatment group (60 cases) and control group (60 cases). Huoxue Bitong Plaster was applied externally in the treatment group, while Goupigao Plaster was used externally in the control group, once a day, for two weeks. The clinical efficacy was evaluated by observing TCM symptom scores, VAS, Oswestry dability index (ODI), and onset time in both groups before and after treatment. Results The total effective rate was 86.67%(52/60) in treatment group, and 85.00% (51/60) in the control group, with no statistical significance (P>0.05). TCM symptom scores of both groups decreased after treatment (P<0.05). For the effect of relieving back pain and morning stiffness, the treatment group was superior to control group (P<0.05). For the effect of relieving waist heaviness, the control group was better than the treatment group (P<0.05). Besides, VAS and ODI of the treatment group were lower than the control group after treatment (P<0.05). The onset time of lightening back pain, morning stiffness in the treatment group was quicker than control group (P<0.05). For waist heaviness, the onset time in control group was quicker than treatment group (P<0.05). Conclusion Huoxue Bitong Plaster has good efficacy for lumbar osteoarthritis with blood stasis and cold-dampness blocking collaterals syndrome.
