Neurophysiological characteristics of patients with chronic lumbalgia
The article presents data characterizing the neurophysiological features of patients with chronic lumbalgia, including the assessment of cognitive functions, emotional responses, by analyzing the parameters and topographic distribution of the cognitive evoked potential P300. The findings suggest that P300 recording allows an objective assessment of whether patients with chronic pain have cognitive pain dysfunction and an altered emotional responsiveness, which are a manifestation of the CNS neuroplasticity phenomenon.
