Facilitation of pain in the human spinal cord by nocebo treatment.
Nocebo hyperalgesia is an increase in subjective pain perception after a patient or subject underwent an inert treatment without any active ingredient. For example, verbal suggestion of increased pain can enhance both pain experience and responses in pain-related cortical brain areas. However, changes in cortical pain responses may be secondary to earlier amplification of incoming pain signals ...
متن کاملFear of pain potentiates nocebo hyperalgesia
Nocebo hyperalgesia has received sparse experimental attention compared to placebo analgesia. The aim of the present study was to investigate if personality traits and fear of pain could predict experimental nocebo hyperalgesia. One hundred and eleven healthy volunteers (76 females) participated in an experimental study in which personality traits and fear of pain were measured prior to inducti...
متن کاملNonconscious activation of placebo and nocebo pain responses.
The dominant theories of human placebo effects rely on a notion that consciously perceptible cues, such as verbal information or distinct stimuli in classical conditioning, provide signals that activate placebo effects. However, growing evidence suggest that behavior can be triggered by stimuli presented outside of conscious awareness. Here, we performed two experiments in which the responses t...
متن کاملPain Ratings, Psychological Functioning and Quantitative EEG in a Controlled Study of Chronic Back Pain Patients
OBJECTIVES Several recent studies report the presence of a specific EEG pattern named Thalamocortical Dysrhythmia (TCD) in patients with severe chronic neurogenic pain. This is of major interest since so far no neuroscientific indicator of chronic pain could be identified. We investigated whether a TCD-like pattern could be found in patients with moderate chronic back pain, and we compared pati...
متن کاملThe magnitude of nocebo effects in pain: a meta-analysis.
The investigation of nocebo effects is evolving, and a few literature reviews have emerged, although so far without quantifying such effects. This meta-analysis investigated nocebo effects in pain. We searched the databases PubMed, EMBASE, Scopus, and the Cochrane Controlled Trial Register with the term "nocebo." Only studies that investigated nocebo effects as the effects that followed the adm...
