Filter by:Dystonia is a devastating disorder defined by involuntary, sustained muscle contractions or abnormal postures that can affect any part of the body. Cervical dystonia (CD) is the most pervasive form of dystonia affecting 60-90,000 individuals in the United States alone and is characterized by involuntary twisting of the neck. The symptoms of CD are disabling, disfiguring, painful, and have a strongly negative impact on quality of life, including social withdrawal and depression. At present, there is no treatment that has been shown to have long term benefit in CD. Standard of care (SOC) is botulinum toxin, which temporarily paralyzes affected muscles, resulting in reduced muscle spasms. This treatment has many undesirable side effects, variable effectiveness, is expensive, and must be repeated every 3 months throughout the lifespan. Physical therapy based treatments aimed at retraining posture or stretching dystonic muscles are largely ineffective and not typically delivered as a part of standard of care. There is an urgent need for novel and effective therapies. Emerging technologies, specifically non-invasive brain stimulation (NBS), have demonstrated compelling evidence to make a meaningful impact in the lives of people with CD. In this study, individuals with cervical dystonia will be randomly assigned to receive tDCS for 15 minutes daily for 4 days in 1 of 4 stimulation location groups. Hypothesis 1: One location of stimulation will result in clear benefit with at least 1 standard deviation (SD) improvement in the CDQ-24, the primary outcome measure, at 1-week follow-up. Hypothesis 2: The cortical silent period will be the most sensitive measure investigated and will demonstrate significant increase in inhibition as determined by an elongation of silent period in the affected upper trapezius muscle. Hypothesis 3: The stimulation location determined to be most effective in Objective 1 will produce the greatest physiologic change in inhibition increase. Hypothesis 4: The hypothesis for this aim is if certain characteristics can predict response to treatment, a strong association will be seen between baseline measure(s) and the primary outcome measure. A thorough assessment of characteristics including: age, sex, duration of symptoms, genotyping for two specific polymorphisms, botulinum toxin history, baseline measures of outcome variables, measures of brain excitability, and genetic testing will predict response.
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.
Investigation of the clinical condition in patients with cervical dystonia by Toronto Western Spasmodic Torticollis Scale (TWSTRS)
Investigation of the clinical condition and safety in patients with cervical dystonia
Cervical dystonia (CD) is the most common focal dystonia. Currently there are no effective oral medications for the treatment of CD. While botulinum toxin injections improve symptoms, they require repeated injections by a trained physician and some patients stop responding to injections or never respond at all. Therefore, alternative treatment options for CD are needed. One new agent is a drug that targets glutamate receptors that are thought to be involved dystonia. This drug, perampanel, was originally developed for epilepsy and is licensed for use in the USA and Canada for treating epilepsy. The purpose of this study is to test the effectiveness of perampanel in treating the symptoms of CD.
This study addresses postures and range of motion in cervical dystonia (Spasmodic Torticollis). It uses 3D miniature and wireless motion captures sensors, and aims to increase the understanding of the biomechanics of the movement disorders of the cervical column in this pathology. In addition, the clinical state of cervical dystonia of the patients will be assessed, using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS). The investigators will compare the results between control and study groups.
The overall objective of this application is to therapeutically target the dysfunctional premotor-motor interaction in dystonia—and to provide a focused treatment of specific anatomical networks in order to reduce side effects and to improve symptom control over conventional therapies.
The objective of this study is to investigate the efficacy of Dysport® in the treatment of cervical dystonia (CD) in a non-interventional long-term study in naïve and pre-treated patients.
This study is a retrospective chart review to evaluate the doses of botulinum Type A toxins BOTOX® (onabotulinumtoxinA) and Xeomin® (incobotulinumtoxinA) used for the treatment of Cervical Dystonia and Blepharospasm in clinical practice.
The purpose of the study is to document long-term response in real-life practice after injection cycles with BoNT-A in subjects suffering from idiopathic cervical dystonia (Long-term clinical and pharmaco-economic data).
