Summary

This study looked at whether hypnosis or a placebo pill (given honestly, without deception) can reduce chronic nerve pain and improve how the brain handles pain. Seventy-two adults with long-term nerve pain were randomly assigned to hypnosis, open-label placebo, or usual care. The goal was to see if these treatments could ease pain and change brain activity linked to pain.
