Subband peak frequencies between responders and nonresponders. (A) Heatmaps showing the subband peak frequency per SCS condition in each EEG region in responders (top-row) and nonresponders (bottom-row). Color bar indicating the frequency in Hz. (B) Correlation analysis between theta peak frequency in CP3-CP4 during HD stimulation and preoperative McGill Pain Questionnaire (MPQ) and Oswestry Disability Index (ODI) scores. (C) Correlation analysis between alpha peak frequency in CP3-CP4 and FP1-FP2 regions during HD stimulation and preoperative Numeric Rating Scale (NRS) scores. Blue circle: Responders. Red diamond: Nonresponders.
