a Timeline of the study, including baseline assessments (left), treatment with electroacupuncture (EA) or control mock laser (ML) acupuncture (center), and post-treatment evaluations (right). b Seven body regions used to assess widespread nociplastic pain, with colors representing the percentage of participants reporting pain in each region for both groups combined prior to treatment. c Illustration of the nociceptive-initiated pressure-pain stimulus applied during functional magnetic resonance imaging (fMRI) sessions. d Block design used in fMRI scans, showing rest, anticipation, and evoked pressure-pain phases.
