Effect of trigger point acupuncture on pain and functional activity in patients with chronic non-specific low back pain: a randomised controlled trial

TrP acupuncture had a significant short-term effect on pain relief and disability in patients with CNLBP, but there was no evidence of a long-term influence (at 8 weeks following the intervention). Further high-quality randomised controlled trials are needed for verification in the future.Trial registration number: ChiCTR1900022838 (Chinese Clinical Trial Registry).
