AbstractAbstract PDFSupplementary Material
Although the KMT2B gene was identified as a causative gene for early-onset generalized dystonia, the efficacy of deep brain stimulation (DBS) in KMT2B-related dystonia has not been clearly elucidated. Here, we describe a 28-year-old woman who developed generalized dystonia with developmental delay, microcephaly, short stature, and cognitive decline. She was diagnosed with KMT2B- related dystonia using whole-exome sequencing with a heterozygous frameshift insertion of c.515dupC (p.T172fs) in the KMT2B gene. Oral medications and botulinum toxin injection were not effective. The dystonia markedly improved with bilateral pallidal DBS (the Burke-Fahn-Marsden Dystonia Rating Scale score was reduced from 30 to 5 on the dystonia movement scale and from 11 to 1 on the disability scale), and she could walk independently. From this case, we suggest that bilateral globus pallidus internus DBS can be an effective treatment option for patients with KMT2B-related generalized dystonia.

AbstractAbstract PDFSupplementary Material
Objective
The aim of this study was to investigate the efficacy of globus pallidus interna deep brain stimulation (GPi-DBS) for treating dystonia due to the GNAL mutation.
Methods
We provide the first report of a dystonia patient with a genetically confirmed GNAL mutation in the Korean population and reviewed the literature on patients with the GNAL mutation who underwent GPi-DBS. We compared the effectiveness of DBS in patients with the GNAL mutation compared to that in patients with DYT1 and DYT6 in a previous study.
Results
Patients with the GNAL mutation and those with DYT1 had higher early responder rates (GNAL, 5/5, 100%; DYT1, 7/7, 100%) than did patients with DYT6 (p = 0.047). The responder rates at late follow-up did not differ statistically among the three groups (p = 0.278). The decrease in the dystonia motor scale score in the GNAL group was 46.9% at early follow-up and 63.4% at late follow-up.
Conclusion
GPi-DBS would be an effective treatment option for dystonia patients with the GNAL mutation who are resistant to medication or botulinum toxin treatment.

AbstractAbstract PDF
Introduction
Exercise can improve both motor and non-motor symptoms in people with Parkinson’s disease (PwP), but there is an unmet need of accessible and sustainable exercise options. This study aimed to evaluate the effect, feasibility, and safety of a regularly performed live-streaming tele-exercise intervention for PwP.
Methods
A live-streaming exercise intervention was implemented twice a week for 12 weeks in PwP. We measured the motor and nonmotor scales in these patients before and after the intervention. Changes in clinical scores from baseline to post-intervention were analyzed using a paired t-test. Factors associated with improvements in clinical scales and compliance were analyzed using Pearson’s correlation analysis.
Results
56 participants were enrolled in the study. There were significant improvements in HADS-A (p = 0.007), HADS-D (p < 0.001), UPDRS part III (p < 0.001), UPDRS total (p = 0.015), H&Y stage (p = 0.027), and PFS-16 (p = 0.026) scores following intervention. Motor improvements were associated with improvements in mood symptoms and fatigue. Higher motor impairment at baseline was associated with a higher compliance rate and better composite motor and non-motor outcomes (ΔUPDRS total score) post-intervention. Overall, the 12-week tele-exercise program was feasible and safe for PwP. No adverse event was reported. Overall adherence was 60.0% in our cohort, and 83.4% were able to participate in more than half of the exercise routines.
Conclusion
The live-streaming tele-exercise intervention is a safe, feasible, and effective non-pharmacological treatment option that can alleviate fatigue and improve mood and motor symptoms in PwP.
