Filter by:The investigators will investigate golfers with visual evidence of an involuntary movement while putting before and after treatment with a low dose of propranolol.
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.
The purpose of this study is to use an investigational device to record brain activity for 12-24 months following surgical implantation of deep brain stimulation (DBS) systems. The goal of the study is better understanding of brain activity in movement disorders and how they relate to DBS, not to bring new devices to market.
The purpose of this study is to study the efficacy and safety of AbobotulinumtoxinA (Dysport) for use in Oromandibular Dystonia (OMD).
Background: - People with dystonia have serious muscle contractions that cause abnormal movements or postures. This significantly affects their daily lives. The common type is called organic. The other type is psychogenic. People with this type have typical symptoms plus some psychological effects. Researchers will look at how rapid transcranial magnetic stimulation (rTMS) of the brain combined with stimulation of a nerve affects the ability to detect sensations. They will compare the responses of people with different types of dystonia. They will also compare the responses of people with dystonia to responses of people without it. This study may help us learn more about the nature of different types of dystonia. Objectives: - To see whether TMS combined with nerve stimulation affects the brain differently in people with different types of dystonia and those without dystonia. Eligibility: - Individuals at least 18 years old, who are right-handed and have dystonia. - Healthy volunteers at least 18 years old. Design: - Participants will have two clinical visits. Each visit will be a few hours long. They can be done on the same day. - Participants will be screened with a medical history and physical exam. - Participants will take several sensory tests. For these tests, electrodes will be placed on their skin. The participants will feel small electric shocks during some of the tests. - Participants will undergo TMS. For 2 minutes, quick electrical currents will pass through a wire coil placed on their head. As this happens, researchers will ask the participants to move certain muscles.
This study investigated the short term effects of repeated administrations of repetitive-transcranial magnetic stimulation (rTMS) on clinical changes and investigate neurophysiologic responses to rTMS of the activated motor system in patients with FHD.
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.
Myoclonus Dystonia is a disease in which myoclonus distort the precision of movements and so cause a handicap in the movements of the everyday life. Response to oral medications may be incomplete and surgery may cause operating risk. Zonisamide is an antiepileptic drug which could bring a therapeutic profit in Myoclonus Dystonia on the severity of the myoclonus.
