Nociceptive-evoked electroencephalography can predict inter-individual differences in high frequency induced sensitisation of central nociceptive pathways: A test-retest reliability study

Baseline and post-HFS evoked-EEG features show poor-to-moderate test-retest reliability across two identical sessions, limiting their use for interventional testing despite detectable sensorimotor changes.

• Why it matters: Evoked-EEG could quantify cortical dynamics during experimentally sensitised pain, but its repeatability and ability to track individual differences in hyperalgesia development needed validation.
• What they did: In the same individuals, HFS conditioning was applied across two identical sessions using a 128mN pin-prick stimulator and single-pulse electrical stimuli, measuring EEG dynamics before and after HFS.
• The result: Post-HFS contralateral central -ERD was significantly strengthened for both modalities, baseline -ERD related to the subsequent SHA time course, while VP magnitude related to general pain intensity and {theta}-ERS reflected habituation rather than SHA specificity.
