Deep brain stimulation
Other studies examined the effects of DBS to both the ventrointermediate nucleus of the thalamus, Vim, and the globus pallidus interna, GPi. Following deep brain stimulation of GPi and Vim, the Unified Myoclonus Rating Scale disability score improved 61-66%. In addition, the Dystomia Rating Scale score improved by 45-48%. While there was no significant difference in improvement between GPi-Vim stimulation and GPi stimulation, GPi-Vim stimulation was significantly more effective than Vim deep brain stimulation alone. Overall, Deep brain stimulation shows promise as a viable treatment for myoclonus dystonia.
