[Somatosensory evoked potentials and their dynamics among trigeminal neuralgia patients during reflexotherapy].

The study of somatosensory evoked potentials (SSEP) in patients with trigeminal neuralgia made it possible to elucidate their characteristic changes as compared to those in healthy subjects. After a course of acupuncture 75% of the patients showed correlation between some parameters of SSEP and positive clinical results. The authors discuss pathophysiological mechanisms of impairment of cortico-subcortical interactions in patients with trigeminal neuralgia and analyze the possibility of using SSEP for dynamic evaluation of the brain status in the process of treatment.
