Active clinical trials for "Dystonic Disorders"

At baseline patients received incobotulinumtoxinA (Xeomin) or placebo. Thereafter, all patients who entered the extension period were treated with up to five injection sessions of incobotulinumtoxinA (Xeomin) during the extension period.

This study aims to compare Botox injections without Physical Therapy sessions to Botox injections combined with Physical Therapy sessions for treatment of Cervical Dystonia. It is expected that Botox combined with Physical Therapy will improve Cervical Dystonia symptoms and quality of life more than Botox alone. It is also expected that Botox combined with Physical Therapy will enhance neuroplasticity, or the ability of the brain to make new connections, more than Botox alone at 4-5 weeks, and remain improved at 12 weeks, after Botox injection.

The purpose of this study was to compare the subthalamic nucleus(STN) with the globus pallidus internus(GPi) as a stimulation target for deep brian stimulation(DBS) for medically refractory 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.

Five hundred patients with a confirmed clinical diagnosis of Cervical Dystonia (CD)are planned for enrollment into this open label study. These patients will be Type B toxin naive patients with CD. During this study patients will receive repeat injections of MYOBLOC when deemed appropriate by the Investigator. However, it will be recommended that injections occur not more frequently than every 12 weeks. Total duration of exposure to MYOBLOC will be targeted for at least two years, with potential exposure for up to 7 years in patients with earliest enrollment

We will apply 16 sessions of rTMS over 4 consecutive days for adult patients suffering from cervical dystonia who receive botox on a regular basis. The TMS protocol will take place 9 weeks following their last botox injection. The primary outcome measure will be improvement in cervical dystonia as measured by the TWSTRS scale. The secondary outcome measures include mood, cognition, gait, TMS measures, and high-density EEG measures.

Objective: Writer s cramp (WC) is a form of focal hand dystonia (FHD). Focal injections of botulinum toxin (BoNT) are the current best therapy. Past studies showed that some types of rehabilitative therapy can be useful. The hypothesis of this study is that BoNT together with a specific type of occupational therapy will be better than BoNT alone for treating these patients. Additionally, studies on WC were hampered by the lack of objective, validated rating scales. In this pilot study, we will assess the value of a new scale compared with older scales. Study population: The study population will consist of 12 WC patients (accrual ceiling of 16). Design: Patients will be randomized so that 6 patients will receive just BoNT therapy and 6 patients will receive BoNT therapy plus occupational therapy. The physical therapy will involve specific exercises of finger movements in the direction opposite to the patient s own dystonic movements, during the writing task. The movements will be isometric against splints made to suit the individual patient. The final outcome will be assessed after 20 weeks of treatment. Patients will be evaluated on several scales, including the writer s cramp rating scale (WCRS) and writer s cramp impairment scale (WCIS), and will also be videotaped. The primary outcome will be based on patient reported subjective scale and the secondary outcomes will be assessed by four blinded raters of the videotapes, done both before and after treatment. Outcome measures: The primary outcome is to show additional improvement from baseline with BoNT therapy plus occupational therapy compared to BoNT alone at 20 weeks using a patient-rated subjective scale. The secondary outcomes are to show improvement in scores of WCRS, WCIS, WCDS, and writing parameters with a new handwriting analysis program. Additionally, the scores obtained from WCRS and WCIS will be compared.

This study will determine if posture and heart rate variability will significantly improve in Parkinsons disease with camptocormia after osteopathic manual treatments dystonia.

Study of Ingrezza (Valbenazine) for the treatment of cervical dystonia.

The aim of this study is to evaluate the organization of the motor circuit in a group of patients suffering from dystonia compared with a group of healthy controls. Deep Brain stimulation is a functional neurosurgery technique consisting in neuromodulation of the motor circuit that has been applied to dystonia. The efficiency of this technique depends on the relative preservation of the function and the structure of the motor network . The assessment of neuronal circuit by advanced techniques of functional neuroimaging in this study might contribute to expand our understanding of the abnormalities in motor circuit activation and the integrity of CNS structure underlying dystonia. This study might contribute therefore to the refinement of Deep brain stimulation indications and techniques in complex dystonia syndromes
