Název v původním jazyce

Induced Cortical Activity Detection using Spectral Analysis of Electroencephalogram

Popis výsledku v původním jazyce

Failed-back surgery syndrome (FBSS) develops after unsuccessful discotomy in some patients. It causes a chronic, neuropathic pain of lower back and legs that cannot be effectively suppressed by chemical analgesics. To alleviate the pain, an electric stimulation of the dorsal spinal cord (SCS) can be applied. Its analgesic effects might be connected with induced rhythmical activity that occurs in pain matrix during the stimulation. Hence, we analyzed EEG recordings of ten patients, whose neuropathic painwas reduced using SCS, to find out whether the SCS induced the cortical oscillations at the same frequency. The analysis was performed using power spectral density (PSD). During SCS, statistically significant increase of PSD was found at the stimulationfrequency over the central midline electrodes in eight patients. The results suggest that SCS induces the oscillatory activity in the medial motor and premotor cortical regions, which can be successfully detected by spectral analysis.
