Onset coordination in essential tremor patients with deep brain stimulation: An EMA study
نویسندگان
چکیده
The present study is the first kinematic study to investigate the speech production of ET patients with VIM-DBS. More specifically, it explores the coordination patterns of articulatory gestures in syllables with simple and complex onsets, CV and CCV, in German. It provides a preliminary analysis of gestural coordination under stimulation for the target words /lima/ and /klima/ in the framework of Articulatory Phonology. The findings reveal a timing deficit in the phonetic realization of competing coupling relations for complex onsets for the patients. The observed perturbation of gestural phase relations can be related to the coupling hypothesis of syllable structure and are taken to be a symptom for dysarthria.

The effects of Thalamic Deep Brain Stimulation on speech dynamics in patients with Essential Tremor: An articulographic study
Acoustic studies have revealed that patients with Essential Tremor treated with thalamic Deep Brain Stimulation (DBS) may suffer from speech deterioration in terms of imprecise oral articulation and reduced voicing control. Based on the acoustic signal one cannot infer, however, whether this deterioration is due to a general slowing down of the speech motor system (e.g., a target undershoot of ...

The technology of Neural Stimulation in recent years has become the focus of the research and treatment, although it has been around for many years. The potential use of stimulating the brain and nerves ranges from the spinal cord stimulation to the implantations of cochlear and bionic eyes with a large discrepancy between the clinical readiness for these various uses. Electrical high-frequency...
متن کاملVocal Tremor: Novel Therapeutic Target for Deep Brain Stimulation
Tremulous voice is characteristically associated with essential tremor, and is referred to as essential vocal tremor (EVT). Current estimates suggest that up to 40% of individuals diagnosed with essential tremor also present with EVT, which is associated with an impaired quality of life. Traditional EVT treatments have demonstrated limited success in long-term management of symptoms. However, v...
