Filter by:This is a randomized, double-blind, placebo-controlled, parallel group, multi-center trial of two doses of daxibotulinumtoxinA (DAXI) for injection (high-dose; low-dose in adult subjects with isolated (primary) cervical dystonia (CD).
The study involves the use of a novel, non-invasive, monitoring device to measure the response to treatment with botulinum toxin injections in 24 (16 Intervention and 8 control) patients with cervical dystonia. A baseline assessment, prior to botulinum treatment,will be structured around validated clinical rating scales for cervical dystonia and questionnaires and the performance of simple neck movements, and will be undertaken while the patient wears a movement sensor attached to the head with an elastic strap. The same assessments will be undertaken at 0, 3, 6, 9 and 12 weeks following treatment to assess response. The patients' treatment will not be affected by their participation in the research. The device readings will then be compared with the clinical ratings to establish whether it might be used as a more sensitive measure of treatment response than clinical assessment alone. This will help clinicians to plan and execute botulinum injections more effectively in future
This study will examine the prevalence of four previously identified non-motor markers in a population of cervical dystonia patients, unaffected family members, and healthy volunteers in an attempt to identify a distinct combination of non-motor symptoms that may be indicative of disease development.
This study occurs during five visits that are already scheduled as part of "Biomarkers to Guide Directional DBS for Parkinson's Disease" (ClinicalTrials.gov Identifier: NCT03353688). If participants have dystonia associated with Parkinson's disease, the investigators will consent and administer one additional rating scale (Burke-Fahn-Marsden Dystonia Rating Scale) to assess the severity of dystonia.
Cortical excitability depends on inhibitory mechanisms efficiency among which long latency intracortical inhibition (LICI) can be studied by paired pulses transcranial magnetic stimulation (TMS). Some recent evidences suggest that LICI may be one of the mechanisms by which the motor comment is adapted to the ongoing motor task with LICI strength being dependent on task complexity. In writer cramp and musician cramp, two forms of dystonia, the cortical excitability is not correctly modulated in some complex gestures. the hypothesis is that this task dependent perturbation of excitability in writer cramp could be due to a lack of LICI efficiency.
To better define the clinical characteristics of oromandibular dystonia, we aimed to study voice, speech and swallowing disorders in idiopathic oromandibular We planned to include consecutive patients followed in Lille Movement disorders department for idiopathic oromandibular dystonia and matched, healthy control subjects. Voice and speech disorders had to be assessed with the phonetic analysis, perceptive analysis and motor examination modules of the "Batterie d'Evaluation Clinique de la Dysarthrie" (Clinical Evaluation of Dysarthria), the Grade, Rough, Breathy, Asthenic, Strained scale, and a computer recording. Activities of daily living had to be assessed with the Oromandibular Dystonia Questionnaire, the Voice Handicap Index and the Deglutition Handicap Index.
There are two phases. Phase I: A single visit which includes a screening, clinical scales, and a MRI scan with simultaneous tES/sham tES in a randomized block design. Enrolls both Cervical Dystonia (CD) patients and healthy controls. Phase II: 5 consecutive days of 30-90 min visits to campus for tES or sham tES. Transcranial magnetic stimulation (TMS) measures and clinical scales will also be included on Day 1 and Day 5 visits. Enrolls only CD patients.
Symptoms of oromandibular dystonia can be alleviated by injections of botulinum toxin. The scope of this study is to describe the efficacy of this procedure, by a retrospective systematic review of patients medical charts
The disability inflected by dystonia encouraged the development of many neurosurgical procedures. This is a prospective study included 120 patients suffering from intractable secondary dystonia. They were subjected to different neurosurgical treatments and were assessed through the follow up period
The purpose of this research study is to investigate how the brain and motor behavior changes in individuals with dystonia and other involuntary movement disorders and healthy individuals over time with exercise training.
