In order to assess the effectiveness of temporary epidural spinal cord neurostimulation in tonic and Burst modes, 47 patients (30–42 years old) with chronic pain resistant to therapy were examined using electroencephalography (EEG) before and after epidural spinal cord neurostimulation with rhythm analysis (alpha, beta, theta, delta) and vertex potential.
Results. Before treatment, EEG disorganization was detected: decreased alpha activity in the parieto-occipital area, increased theta and delta rhythms in the fronto-central lead, and the presence of vertex potential. Tonic stimulation reduced pain syndrome in 63 % of patients, partially normalizing the alpha rhythm, but maintaining theta activity. Burst mode (500 Hz, 40 Hz) was more effective: pain relief was registered in 95 % of patients, restoration of physiological rhythms (increase in alpha activity in the centro-parietal area, decrease in pathological theta and delta waves), disappearance of vertex potential was found in the majority of patients.
The obtained data indicate that EEG disorganization and vertex potential serve as objective biomarkers of chronic neuropathic pain, and EEG monitoring confirms the effectiveness of epidural spinal cord neurostimulation, emphasizing more pronounced and stable analgesic effect of Burst stimulation.
The study emphasizes the role of EEG in objectifying the neuropathic pain treatment.
Keywords:neuropathic pain syndrome, electroencephalography, epidural stimulation.
