【Abstract】 Objective To observe the clinical effect of traditional therapy on syndrome of cold-dampness in nonspecific low back pain. Methods114 patients were randomly divided into Tianjiu group (treatment with conventional Tianjiu)，Tibet medicine bath group (treatment with “Wuwei-Ganlu”)，and control group (treatment with celecoxib) in a ratio of 1：1：1 for one treatment course. The visual analogue scale (VAS) and Oswestry Dysfunction Index (ODI) scores of patients in each group were measured before treatment，at the end of treatment course，and at 1 and 2 months after treatment course. ResultsFive patients did not finish the therapy，and 38，37，and 34 patients were included for statistical in Tianjiu group，Tibet medicine bath group，and control group，respectively. There were no significant difference in gender，age，VAS and ODI scores among the three groups (P>0.05)，suggesting that the baseline of patients in the three groups was consistent. However，at the end of 1 course of treatment，the primary efficacy evaluation indexes VAS and ODI of 3 groups were significantly different from those before treatment (P<0.05)，but there was no significant difference between groups (P>0.05). These results suggesting that the efficacy of traditional therapy was comparable to that of western medicine group. Two months after the end of treatment，VAS and ODI scores in Tianjiu group and Tibet medicine bath group were lower than those in control group，and the differences were statistically significant (P<0.05). It is suggesting that traditional therapy was better than the treatment of celecoxib in the recurrence rate of low back pain. ConclusionLingnan conventional Tianjiu is an effective and safe traditional therapy for nonspecific low back pain，which is worth popularizing.
