Neurofeedback for the Management of Neuropathic Pain in People With Diabetes

We will conduct a high-quality, blinded, randomized controlled trial (RCT) to rigorously test the effectiveness of EEG-based NF in patients with diabetes-related neuropathic pain. This study aims to determine the short-term and long-term effects of EEG-based NF on self-reported pain intensity, neuropathic pain symptoms, daily functioning, QoL and neurophysiological activity in individuals with chronic P-DPN. The trial is designed as a superiority trial. The primary aim is to evaluate whether real EEG-NF compared with sham EEG-NF, leads to a greater reduction in self-reported pain intensity from T0 to T1, assessed using mean 7-day pain intensity derived from the electronic pain diary. Secondary aims are to examine whether EEG-NF improves neuropathic pain severity, pain interference, sleep, fatigue, mood and QoL, and promotes normalization of activity within predefined pain-related cortical networks assessed using z-score changes in standardized weighted low-resolution electromagnetic tomography (swLORETA)-derived regions.
