University Hospital, Ghent
ClinicalTrials.gov Identifier:
NCT00782249
First received: October 29, 2008
Last updated: January 29, 2013

  Purpose

Patients with refractory epilepsy who are candidates for a treatment with vagus nerve stimulation will be prospectively randomized into 3 arms with different vagus nerve stimulation paradigms. Vagus nerve stimulation parameters are programmed and adjusted during outpatient clinic visits, within the normal clinical practice.
