Efficacy and safety of thread embedding acupuncture for chronic low back pain: a randomized controlled pilot trial.

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).
