Effect of Deep Brain Stimulation of the Globus Pallidus Internus on Quality ofLife in Young Patients with Dyskinetic Cerebral Palsy (STIM-CP): a ProspectiveSingle-Arm Multicenter Trial with a Double-Blind Cross-Over at 12-MonthsFollow-up
TLDR
This is the first prospective trial investigating the effects of GPi-DBS on motor and non-motor outcome in a cohort of exclusively pediatric patients in a multicenter setting and chooses the mean change in the CPCHILD questionnaire from baseline to 12 months as the primary outcome parameter.
Thalamic deep brain stimulation for acquired dystonia in children and young adults: a phase 1 clinical trial.
TLDR
Bilateral thalamic neuromodulation by DBS for severe, medication-refractory acquired dystonia was well tolerated and primary and secondary outcomes showed highly variable treatment effect sizes comparable to those of pallidal stimulation in this population.
Pallidal deep brain stimulation in individuals with dystonia due to cerebral palsy: expanded experience
TLDR
Pallidal deep brain stimulation offers an effective option for the amelioration of severe motor dysfunction in individuals with dystonia due to cerebral palsy and is seen by 6 months, and maintained even after two or more years of stimulation.
Subthalamic Nucleus Deep Brain Stimulation in Post-Infarct Dystonia
TLDR
It is demonstrated that subthalamic nucleus (STN) DBS could be an alternative in the management of post-infarct dystonia in patients with abnormal striatal anatomy which precludes GPi DBS.
Treatment of secondary dystonia with a combined stereotactic procedure: long-term surgical outcomes
TLDR
It is demonstrated that DBS plus unilateral ventralis oralis thalamotomy for CP patients with fixed states in the upper extremities is useful not only to treat secondary dystonic movement but also to improve quality of life.
Causes of failure of pallidal deep brain stimulation in cases with pre-operative diagnosis of isolated dystonia.
Deep brain stimulation for dystonia due to cerebral palsy: A review.
Deep Brain Stimulation in Children with Dystonia: Experience from a Tertiary Care Center
TLDR
GPi DBS is an effective and safe therapy in pediatric patients with primary as well as selected cases of secondary dystonia.
Subthalamic Nucleus Deep Brain Stimulation Lessens Acquired Dystonia: Report of Two Patients and Systematic Review of Published Cases
TLDR
Subthalamic DBS is likely efficient for acquired dystonia, and age at surgery was inversely correlated with postoperative improvement and no serious complications were found.

Bilateral deep-brain stimulation of the globus pallidus in primary generalized dystonia.
TLDR
These findings support the efficacy and safety of the use of bilateral stimulation of the internal globus pallidus in selected patients with primary generalized dystonia.
Pallidal Stimulation for Dystonia
TLDR
High-frequency deep brain stimulation of the globus pallidus internus of the GPi is a new and promising treatment option for severe dystonia and secondary worsening may limit this therapy.
Acute deep-brain stimulation of the internal and external globus pallidus in primary dystonia: functional mapping of the pallidum.
TLDR
The varying effects across patients of bilateral acute dorsal pallidal stimulation suggest that unknown factors associated with dystonia could have a role in and contribute to the effects of the electrical stimulation.
Chronic stimulation of the globus pallidus internus for treatment of non-dYT1 generalized dystonia and choreoathetosis: 2-year follow up.
TLDR
Chronic pallidal DBS is a safe and effective procedure in generalized non-DYT1 Dystonia, and it may become the procedure of choice in patients with medically refractory dystonia.
Treatment of dystonic syndromes by chronic electrical stimulation of the internal globus pallidus.
TLDR
Electrical stimulation of the internal globus pallidus proved to be an effective treatment for generalized dystonia and should be considered as first-line therapy in children and adults.
Primary Dystonia Is More Responsive than Secondary Dystonia to Pallidal Interventions: Outcome after Pallidotomy or Pallidal Deep Brain Stimulation
TLDR
This study indicates that primary dystonia responds much better than secondary dySTONia to pallidal procedures, and could not distinguish a difference in efficacy between pallidotomy and pallidal deep brain stimulation.
Sixty hertz pallidal deep brain stimulation for primary torsion dystonia
TLDR
Stimulation of the internal globus pallidus at 60 Hz is safe and effective for treating medically refractory primary dystonia and shows a progressive median improvement of their BFMDRS motor subscores.
Pallidal deep-brain stimulation in primary generalized or segmental dystonia.
TLDR
Bilateral pallidal neurostimulation for 3 months was more effective than sham stimulation in patients with primary generalized or segmental dystonia and sustained improvement in all movement symptoms, the level of disability, and quality of life, as compared with baseline scores.
LOCATION OF ACTIVE CONTACTS IN PATIENTS WITH PRIMARY DYSTONIA TREATED WITH GLOBUS PALLIDUS DEEP BRAIN STIMULATION
TLDR
The location of the active contacts used for globus pallidus internus deep brain stimulation was similar in patients with cervical dystonia, generalized dySTONia, and Parkinson's disease.

TLDR
I read with interest the recent case report by Chang and colleagues on unilateral deep brain stimulation (DBS) of the globus pallidus internus (GPi) in a patient with delayed-onset posttraumatic cervical dystonia, and report that during chronic stimulation the patient’s cervical dySTONia improved, and that he could turn his head to the midline easier than preoperatively.
