Classical conditioning differences associated with chronic pain: a systematic review

Prominent clinical models of chronic pain propose a fundamental role of classical conditioning in the development of pain-related disability. If classical conditioning is key to this process, then people with chronic pain may show a different response to pain-related conditioned stimuli (CS) than healthy controls. We set out to determine whether this is the case by undertaking a comprehensive and systematic review of the literature. To identify studies comparing classical conditioning between people with chronic pain and healthy controls, the databases MEDLINE, PsychINFO, PsychARTICLES, Scopus, CINAHL, were searched using key words and MESH headings consistent with ‘classical conditioning’ AND ‘pain’.
