Filter by: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).
The purpose of the protocol is to assess the long term safety of repeat treatment cycles of Dysport® 500 U using 2 mL dilution scheme for the treatment of Cervical Dystonia. This is an extension study to study A-TL-52120-169 (hereafter referred to as Study 169).
The purpose of the protocol is to evaluate the efficacy and safety of Dysport® using 2 mL dilution compared with placebo for the treatment of Cervical Dystonia.
This study is exploring a new experimental procedure in dystonia called repetitive transcranial magnetic brain stimulation (TMS) combined with rehabilitation. The purpose of the study is to determine whether repetitive TMS is effective as a treatment to reduce symptoms in dystonia as demonstrated by improved motor performance.
In this study, the investigators will monitor extracellular neurotransmitter levels using a probe that is able to perform real time electrochemical detection during deep brain stimulation surgery. The overall question this study is designed to answer is: Are there neurotransmitters released during deep brain stimulation?
The aim of this study is to asses the efficacy and the clinical safety of the transcranial magnetic resonance guided high intensity focused ultrasound system ExAblate 4000, InSightec Ltd. for functional neurosurgery in the treatment of movement disorders. The treatments to be conducted in this study are non-invasive, i.e. without opening the skull, and will create microthalamotomies in specific target areas such as thalamus, subthalamus and pallidum. The data obtained in this study will be used to evaluate the basic safety aspects of this new treatment technology and will serve as a basis for the clinical introduction of MR-guided ultrasound neurosurgery.
The purpose of this research study is to determine the physical brain changes in people with cervical dystonia after deep brain stimulation (DBS) surgery and as compared to healthy controls. We will do this by measuring your body's response to transcranial magnetic stimulation (TMS) before and/or after DBS surgery. TMS is a non-invasive procedure during which you sit in a chair that looks like one you would find at the dentist's office. A nerve stimulator is placed on the wrist of the right hand to stimulate the median nerve; the intensity of the nerve stimulator is gradually increased until the right thumb begins to twitch. A magnetic coil is placed on the scalp on one side of the head, overlying the brain's motor cortex, to stimulate the brain's output to the muscles in the opposite hand. If you are a control subject, and therefore will not/have not have DBS surgery, we will measure the body's response to TMS for comparison purposes. We expect that the electrical differences in the brain may be related to the physical benefits some patients with primary cervical dystonia receive from DBS surgery.
This is an observational study to assess health-related quality of life in patients with cervical dystonia (dystonie) treated with OnabotulinumtoxinA per routine clinical practice.
The purpose of this study is to determine the Optimal dose for safety and efficacy in the treatment of cervical dystonia.
Background: - People with writer s cramp develop tightness in arm muscles and abnormal hand posture when writing, which makes writing difficult or impossible. At present, there is no suitable rating scale to measure the symptoms of or disability associated with writer s cramp. Researchers want to videotape people performing simple writing tasks. They will then compare the performance of people with writer s cramp on these tasks to those of people without writer s cramp. This information will help develop a rating scale to evaluate writer s cramp. Objectives: - To develop a new rating scale for writer s cramp. Eligibility: - Individuals at least 18 years of age who have writer s cramp. Design: - Participants will be screened with a physical exam and medical history. - Participants will have one outpatient study visit that will last about 3 hours. - Participants will perform tasks related to writing, such as writing passages and drawing spirals and loops. They will be videotaped during these tasks. They will repeat some of the writing tasks three more times; on paper attached to a writing tablet, directly on the writing tablet, and on a computer tablet. - The angles made by the joints will be measured at rest not while writing healthy volunteers.
