Pallidal stimulation is a convincing and valid alternative for primary generalized dystonia refractory to medical therapy or botulinum toxin. However, the clinical outcome reported in literature is variable most likely because of heterogeneity DBS techniques employed and /or to clinical dystonic pattern of the patients who undergo surgery. In this study, we(More)
BACKGROUND AND PURPOSE Bilateral globus pallidus deep brain stimulation (GPi-DBS) represents an effective and relatively safe therapy for different forms of refractory dystonia. The aim of this study was to assess, retrospectively, the effect of two different stimulation settings during GPi-DBS in 22 patients affected by primary generalized or(More)
BACKGROUND AND PURPOSE For many years deep brain stimulation (DBS) devices relied only on voltage-controlled stimulation (CV), but recently current-controlled devices have been developed and approved for new implants as well as for replacement of CV devices after battery drain. Constant-current (CC) stimulation has been demonstrated to be effective in new(More)
