Nocebo Effect on Pain-Related Autonomic Responses in a State of Experimentally-Induced Sensitization. [PDF]
Eur J PainABSTRACTBackgroundEnhanced pain‐related autonomic responses were reported after experimentally‐induced secondary mechanical hyperalgesia (SMH) in healthy individuals as well as in a variety of chronic pain cohorts. Stimulus‐induced autonomic responses can also be modulated by positive and negative expectations towards the applied stimulus.
