Objective. The aim of this study was to examine the hypothesis that subcutaneous occipital stimulation influences pain due to occipital neuralgia. Materials and Methods. Between 2001 and 2004 eight patients with intractable occipital neuralgia were referred to our center. Their records were reviewed. ⋯ The total quantity of opiates taken after implantation showed a marked reduction. Of the seven who had a permanent implant two acquired full-time employment. Conclusion. Occipital neuralgia is a useful and reversible treatment for intractable occipital neuralgia.

Introduction. Neuromodulation, mediated by invasive electric stimulation, has been shown to be effective when applied to patients with refractory and intractable neuropathic pain. Recent advances in neurostimulation have broadened the therapeutic uses of this therapy, with the placement of extraspinal electrodes for peripheral nerve stimulation. Methods. Four patients with long-evolving, persistent, severe, uncontrolled, and localized pain in the occipital region, in whom other management options had been tried and failed, were treated with a peripheral, occipital, extraspinal electric stimulation (C1-C2-C3). ⋯ Results. In all cases, stimulation of the occipital region yielded good or very good global results. In all patients, continuous pain disappeared, the frequency and severity of the episodic pain decreased, function improved, and restful sleep improved. As a result of stimulation we were either able to reduce or discontinue medication usage in all of our patients.

Introduction. Since its first application in 1967, numerous case series indicate that spinal cord stimulation (SCS) is an effective treatment for the management of failed back surgery syndrome (FBSS). However, only one randomized controlled trial has demonstrated that SCS provides more effective pain relief than re-operation and conventional medical management. The PROCESS randomized, controlled, multicenter trial aims to assess the clinical effectiveness and cost-effectiveness of SCS when added to conventional medical management compared to conventional medical management alone in patients with FBSS. ⋯ At the 6-month visit, patients will be classified as successful (≥ 50% pain relief in the legs) or unsuccessful (< 50% pain relief in the legs). If the results of the randomized treatment are unsuccessful, patients can cross over to the alternative treatment arm. Discussion. This paper highlights the rationale, design, methods, and challenges of an ongoing prospective, randomized, controlled, multicenter clinical trial that has been undertaken to obtain conclusive evidence of the clinical efficacy and cost-effectiveness of an SCS system in patients with FBSS.
