The influence of placebo analgesia manipulations on pain report, the nociceptive flexion reflex, and autonomic responses to pain

Placebo analgesia is pain reduction evoked by sham treatment (e.g., inert cream). Because the treatment has no active ingredient, this implies psychosocial processes are involved. Among the processes identified are 1) expectations for pain relief usually induced by verbal suggestion (e.g., “This cream is a powerful painkiller”) and 2) experience/conditioning usually induced by pairing the sham treatment with pain reduction (achieved in experiments by surreptitious lowering of the painful test stimulus)1,39.
