Objectives. To study the impact of personality traits on the effect of neurostimulation in patients with chest pain and normal coronary arteries. Materials and Methods. Using the Dutch personality questionnaire, we retrospectively studied the personality traits in 33 patients treated with neurostimulation, either transcutaneous electrical nerve stimulation or spinal cord stimulation after 5 years. Neurostimulation was successful in 21 patients. ⋯ In univariate analyses, low scores at the "social inadequacy" scale and the use of calcium antagonists were associated with beneficial outcome of neurostimulation. In multivariate analysis low scores at the "social inadequacy" scale remained an independent predictor for beneficial neurostimulation outcome, when adjusted for other variables. Conclusion. Personality traits are a determining factor in the evaluation of neurostimulation for patients with chest pain and normal coronary arteries.

Clinical neurophysiology has always played an important interventional role throughout the perioperative stages in functional neurosurgery. On the one hand, some neurophysiologic procedures have become an integrated part of neurosurgery. On the other hand, in deep brain stimulation, although the surgical electrode implantation is an essential step, the therapeutic effects are actually produced by electrically modulating the physiologic activity of the brain. We review the topic of neurophysiologic intervention in the deep brain stimulation for movement disorders by presenting the evidence derived from our own experiences based on an integrated group located at two hospitals in London and Oxford, UK, and mainly covering tremor caused by multiple sclerosis, Parkinson's disease and dystonia.

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.

Objective. Neurally augmented sexual function (NASF) is the production of pleasurable genital stimulation and subsequent orgasm through the application of electrical energy to provide stimulation of the spinal cord or peripheral nerves. The purpose of this paper is to demonstrate the reproducibility of this phenomenon. Materials and Methods. Eleven otherwise healthy women, ages 32-60 years, were selected for this study. ⋯ Conclusions. Pleasurable genital stimulation of the spinal cord is a consistently reproducible phenomenon. In a subset of the population studied, improvement in orgasmic function was noted. This was noted in the group with secondary orgasmic dysfunction.
