Abstract：Objective：To observe the effect of the therapy of warming-needle moxibustion combined with joint loosening on the lumbar mobility，Numerical Rating Scale of Pain(NRS) and Oswestry Disability Index(ODI) in patients with chronic low back pain. Methods：A total of 92 patients with chronic low back pain were selected and divided into the control group and the study group according to the random number table method，46 cases in each group. The control group was treated with joint loosening and the study group was additionally treated with warming- needle moxibustion based on the treatment of the control group. The clinical effect was compared between the two groups. The lumbar mobility，scores of NRS，ODI and satisfaction，and continuous sitting time were observed in the two groups. Results：The total effective rate was 93.48% in the study group，higher than that of 78.26% in the control group(P＜0.05). After treatment，the mobility of forward flexion， extension and lateral flexion，and the continuous sitting time in the two groups were all higher than before treatment(P＜ 0.05)，and those in the study group were higher than those in the control group(P＜0.05). After treatment，the scores of NRS and ODI in the two groups were decreased when compared with those before treatment(P＜0.05)，and the scores of NRS， ODI and satisfaction in the study group were lower than those in the control group(P＜0.05). Conclusion：The therapy of warming- needle moxibustion combined with joint loosening has a good therapeutic effect on the patients with chronic low back pain，which can enhance the lumbar mobility，relieve the lumbar muscle spasm，and promote the recovery of lumbar function，with high satisfaction.
