Research Review Summary

Needling point location used in sham acupuncture for chronic nonspecific low back pain, a systematic review and meta-analysis

Key takeaways
  • Sham-controlled randomized trials can give us insight into the mechanisms behind how certain interventions work
  • Narratives regarding mechanism of action for interventions should be influenced by existing sham-controlled research
  • Sham-controlled studies that find a positive effect for the studied intervention in the presence of a non-convincing sham should be given less weight
  • Interventions that have been shown to be no more effective than convincing sham can still be used, but caution should be taken in making claims about specificity of the intervention
