PURPOSE Chronic deep brain stimulation of the nucleus ventralis intermedius is an effective treatment for individuals with medication-resistant essential tremor. However, these individuals report that stimulation has a deleterious effect on their speech. The present study investigates one important factor leading to these effects: the coordination of oral and glottal articulation. METHOD Sixteen native-speaking German adults with essential tremor, between 26 and 86 years old, with and without… Expand
The effects of Thalamic Deep Brain Stimulation on speech dynamics in patients with Essential Tremor: An articulographic study
TLDR
Analysis of acoustics and articulatory patterns of the labial and lingual system using Electromagnetic Articulography in twelve Essential Tremor patients treated with thalamic DBS and twelve age- and sex-matched controls shows that critical changes in speech dynamics occur on two levels: with inactivated stimulation (DBS-OFF), patients showed coordination problems of thelabial and Lingual system in terms of articulatory imprecision and slowness. Expand
The Effects of Deep Brain Stimulation on Speech Intelligibility in Persons With Essential Tremor.
TLDR
Chronic cZi-DBS, optimized for tremor suppression, does not generally affect speech intelligibility in persons with essential tremor, and speech intelligible may be preserved in many individuals, even when stimulated at high amplitudes. Expand
Intraoperative Evaluation of Essential Vocal Tremor in Deep Brain Stimulation Surgery.
TLDR
Using a noninvasive, simple acoustic recording method, a speech-language pathologist can conduct intra-operative evaluation of EVT during DBS surgery and demonstrate immediate, intraoperative improvements in EVT. Expand
Onset coordination in essential tremor patients with deep brain stimulation: An EMA study
TLDR
A timing deficit is revealed in the phonetic realization of competing coupling relations for complex onsets for patients with VIM-DBS, revealing a symptom for dysarthria. Expand
Precise stimulation location optimizes speech outcomes in essential tremor.
TLDR
Optimal speech outcomes were achieved in 44% of patients and correlated with precise stimulation location within and not outside of the VLp, which was greater for patients with dysarthria than those with normal speech. Expand
Coordination patterns in Essential Tremor patients with Deep Brain Stimulation: Syllables with low and high complexity
TLDR
It is shown that the behavior of the speech system changes when the stimulation was activated, inducing a change in the dynamical system the ET patients have to adapt to, and coordination problems are not categorical but gradient in nature. Expand
The effects of thalamic and posterior subthalamic deep brain stimulation on speech in patients with essential tremor – A prospective, randomized, doubleblind crossover study
TLDR
Speech in ET patients without DBS can be impaired, dependent on patient's individual characteristics, and the PSA can be considered an alternative DBS target in ET without higher risk of dysarthria. Expand
Intragestural Variation in Natural Sentence Production: Essential Tremor Patients Treated with DBS
TLDR
The authors' analysis revealed that intragestural coordination patterns are affected in the patients’ group, and similarities in that there is a slowing down of the system, but also differences in that coordination problems increase in DDK leading to an overmodulation of peak velocities and displacements. Expand
Dissociating oral motor capabilities: Evidence from patients with movement disorders
TLDR
The results disclosed statistically significant dissociations between movement rates obtained from the speech task and those obtained from speech‐like and nonspeech oral motor tasks in a number of patients, which can be interpreted as reflecting major differences in task demands and underlying control mechanisms. Expand
Network fingerprint of stimulation-induced speech impairment in essential tremor
TLDR
It is demonstrated that SID in essential tremor patients is associated with both, motor cortex and cerebellar connectivity and the identified fiber-based atlas structure might contribute to future postoperative programming strategies to achieve optimal tremor control without speech impairment in ET patients with thalamic DBS.

Effect of deep brain stimulation on different speech subsystems in patients with multiple sclerosis.
TLDR
Different effects on the two speech subsystems are induced by electrical stimulation of the thalamus in patients with MS, and the precision of glottal and supraglottal articulatory gestures is reduced and phonation has a greater tendency to be hyperfunctional in comparison with the healthy control data. Expand
Reduction in voice tremor under thalamic stimulation
TLDR
It appears that reduced voice tremor may be an additional benefit of DBS for some individuals. Expand
Articulatory deficits in parkinsonian dysarthria: an acoustic analysis.
TLDR
The results indicate that motor planning of speech differs from arm movement control, and articulatory "undershoot" was not uniform but influenced by linguistic demands in that the closures associated with a stressed syllable were performed at the expense of unstressed ones. Expand
Chronic electrical stimulation of the ventralis intermedius nucleus of the thalamus as a treatment of movement disorders.
TLDR
Chronic VIM stimulation, which is reversible, adaptable, and well tolerated even by patients undergoing bilateral surgery and by elderly patients, should replace thalamotomy in the regular surgical treatment of parkinsonian and essential tremors. Expand
Bilateral thalamic deep brain stimulation: midline tremor control
TLDR
Unilateral thalamic stimulation significantly improves midline tremor, and subsequent bilateral thalamo-bilateral stimulation offers an additional incremental improvement in mid line tremor control. Expand
The contribution of the cerebellum to speech production and speech perception: Clinical and functional imaging data
TLDR
A prearticulatory verbal code bound to reciprocal right Cerebellar/left frontal interactions might represent a common platform for a variety of cerebellar engagements in cognitive functions. Expand
Deep brain stimulation of the ventral intermediate nucleus in patients with essential tremor: Stimulation below intercommissural line is more efficient but equally effective as stimulation above
TLDR
The data suggest that sub-ICL stimulation may be more efficient compared to thalamic stimulation but equally effective when patients' individual stimulation parameters are used. Expand
Task-Related Factors in Oral Motor Control: Speech and Oral Diadochokinesis in Dysarthria and Apraxia of Speech

TLDR
Overall, dysdiadochokinesis was correlated with the degree of speech impairment, but there was a strong interaction between task type and motor speech syndrome, which affected DDK to a relatively greater extent than sentence production. Expand
Long-term evaluation of deep brain stimulation of the thalamus.
TLDR
Thalamic stimulation is safe and effective for the long-term management of essential and Parkinsonian tremors and Bilateral stimulation can cause dysarthria and incoordination and should be used cautiously. Expand
Synchronized brain network associated with essential tremor as revealed by magnetoencephalography
TLDR
The results are consistent with the view that in ET, a network of cerebral areas including brainstem shows oscillatory interactions, which lead to a rhythmic modulation of muscle activity becoming apparent as tremor. Expand
