Popis: Background We investigated the efficacy and safety of thread-embedding acupuncture (TEA) for chronic low back pain (LBP) in a randomized controlled pilot trial with the aim of laying the foundation for a large-scale randomized controlled trial on this topic. Methods Forty participants were recruited for this two-arm, assessor-blinded randomized controlled pilot trial. The participants were randomly allocated to a TEA group (experimental group) or an acupuncture group (control group). The TEA group received TEA once every 2 weeks for 8 weeks (four sessions in total), while the acupuncture group received acupuncture twice per week for 8 weeks (16 sessions in total). The primary outcome was the visual analog scale (VAS) score for pain and the secondary outcomes were short-form McGill Pain Questionnaire (SF-MPQ) and Oswestry Disability Index (ODI) scores. Assessments were performed at screening and at 2, 4, 6, 8, and 10 weeks after treatment initiation (the 10-week assessment was conducted at 2 weeks after treatment cessation). Results Of the 40 participants, 36 completed the study and four dropped out. Both the TEA group and the acupuncture group showed significant improvements in VAS, SF-MPQ, and ODI scores in a time-dependent manner. Furthermore, with regard to ODI, a significant interaction between group and time was observed, with the two groups exhibiting a different pattern of change at 8 weeks according to contrast analysis with Bonferroni’s correction. No serious adverse event occurred, and hematological and biochemical test findings were within normal limits. Conclusion This pilot study has provided basic data for a larger clinical trial to demonstrate the efficacy and safety of TEA for chronic LBP.
