Pallidal deep brain stimulation improves quality of life in segmental and generalized dystonia: Results from a prospective, randomized sham‐controlled trial

As part of the first randomized, sham‐timulation controlled trial on deep brain stimulation (DBS) in primary segmental or generalized dystonia, health‐related quality of life (HRQoL) was assessed by SF‐36. After the 3‐month sham‐controlled phase, significant HRQoL improvement occurred only in the active‐stimulation group. The open‐label extension phase resulted in a significant improvement in all SF‐36 domains following 6 months of neurostimulation. These results demonstrate a favorable impact of DBS on HRQoL in primary dystonia. © 2007 Movement Disorder Society
