Acute Effects of High Frequency Vagal Nerve Stimulation on Balance and Cognitive Motor Performance in Epilepsy: Three Case Study Reports

Quantitative measures of area of sway, total sway, and cognitive function failed to show significant differences in acute (50 minute) “ON-OFF-ON-OFF” studies of high frequency left vagal stimulation in three epileptic patients undergoing treatment for chronic complex partial seizures. Fluctuation in Wood levels of anticonvulsants may have been associated with some clinicaJ effects. There were no significant adverse effects of acute left vagal stimulation in these three subjects.
