Effects of non-pharmacological pain treatments on brain states
Open accessAbstract
Objective To (1) evaluate the effects of a single session of four non-pharmacological pain interventions, relative to a sham tDCS procedure, on pain and electroencephalogram- (EEG-) assessed brain oscillations, and (2) determine the extent to which procedure-related changes in pain intensity are associated with changes in brain oscillations. Methods 30 individuals with spinal cord injury and chronic pain were given an EEG and administered measures of pain before and after five procedures (hypnosis, meditation, transcranial direct current stimulation [tDCS], neurofeedback, and a control sham tDCS procedure). Results Each procedure was associated with a different pattern of changes in brain activity, and all active procedures were significantly different from the control procedure in at least three bandwidths. Very weak and mostly non-significant associations were found between changes in EEG-assessed brain activity and pain. Conclusions Different non-pharmacological pain treatments have distinctive effects on brain oscillation patterns. However, changes in EEG-assessed brain oscillations are not significantly associated with changes in pain, and therefore such changes do not appear useful for explaining the benefits of these treatments. Significance The results provide new findings regarding the unique effects of four non-pharmacological treatments on pain and brain activity.

Many of the differences in processing between high and low hypnotizability individuals are associated with frontal areas of the brain associated with executive control.
“and that many of the differences in processing are associated with those (frontal) areas of the brain associated with executive control (Jensen et al., 2013).”
From Hypnotic approaches for chronic pain management: Clinical implications of recent research findings. (2014) · cites this paper as Jensen et al., 2013
The Results section reports hypnosis-related EEG changes at frontal sites, which supports the frontal-location part of the claim. It does not compare people with high and low hypnotizability or link differences in their processing to executive control; the reported theta changes also appeared at posterior sites. No page number is available in our copy. (LLM, conf=0.76)
Experimental — accuracy not yet measuredIndividuals who score high on tests of hypnotizability process information differently from those who score low on hypnotizability tests.
“Neurophysiological research provides preliminary support for these ideas in that individuals who score high on tests of hypnotizability (highs) clearly process information differently from those who score low on hypnotizability tests (lows)”
From Hypnotic approaches for chronic pain management: Clinical implications of recent research findings. (2014) · cites this paper as Jensen et al., 2013
The Results section reports EEG changes after hypnosis, not differences between people who score high and low on hypnotizability tests. Searches for hypnotizability, hypnotic susceptibility, and high-versus-low comparisons found no passage in our copy addressing the claimed difference in information processing; page numbers were not available.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
