Clinical Trial Summary

Medically intractable pain caused by occipital neuralgia can be very difficult to control with traditional pain management. Peripheral nerve stimulation which is used in migraines and cluster headache can be an alternative for these patients with occipital neuralgias when medical treatment and traditional pain management have failed (drugs for neuropathic pain, infiltrations, psychobehavioral approaches and multidisciplinary approach in a pain center). Occipital nerve stimulation consists to put a lead subcutaneously in front of the occipital nerve and to connect the lead to a pulse generator. A retrospective study of 60 patients was conducted in Nantes University Hospital. The results were good with the Visual Analog Scale (VAS) decreased from 8.4 preoperatively to 2.85 postoperatively. The medical quantification scale (MQS) was reduced to about 50% (18 preoperatively versus 9.9 postoperatively). Stimulation was quiet stable over time with a mean follow-up of 24 months (range 6 to 72 months). The aim of StimO is to confirm this result through a national controlled randomized multicenter study where occipital nerve stimulation will be compared to the optimal medical management.
