Objectives This study was designed to investigate the effects of wet cupping on Wisu (BL12) in non-acute low back pain patients. Methods We recruited 30 participants for this study. Fifteen patients were randomly assigned to the Wisu (BL21) treatment group (WT group) and 15 were assigned to the non-acupoint treatment group (NT group). Both groups were treated with the pricking-cupping bloodletting method three times. Values at baseline and follow-up were analyzed by Wilcoxon signed rank test and the differences between the two groups were determined by Wilcoxon rank sum test. p-values less than 0.05 were considered significant. The primary outcome was the visual analogue scale (VAS), and secondary outcomes were the Oswestry disability index (ODI), Rolland-Morris disability questionnaire (RMDQ), Euroqol-5 dimension questionnaire (EQ-5D) and finger-to-ground distance (FTGD). These outcomes were measured on the day of first treatment before the procedure and on follow-up 7 days after the last treatment. Results Significant changes were identified in the VAS for pain and ODI in each group after wet cupping treatment on Wisu (p<0.05). However, no significant changes were found between groups. Meanwhile, RMDQ and EQ-5D were significantly decreased only in the NT group (p<0.05) without any differences between groups. FTGD was decreased in both groups, but not significantly. Conclusions Wet cupping with both Wisu treatment and non-acupoint had significant effects on non-acute low back pain, although there were no differences between the two groups. A large-scale study is needed to identify the effect of wet cupping on Wisu.
