Filter by:The goal of this clinical trial is to develop a system which can be used to measure movements in people with Essential Tremor (with or without dystonia). The main questions it aims to answer are: - Can individuals with Essential Tremor be distingushed from individuals without tremor using Virtual Reality (VR) - Can the current Essential Tremor Assessment Scale (the TETRAS) be reproduced in VR - Can Essential Tremor be quantified using a measurement system - Can Dystonia be quantified using a measurement system. Participants will don the equipment used to measure their tremor and replicate a series of standardised movements to measure their tremor, in and out of the VR platform. The assessment will take no longer than an hour.
The goal of this clinical study is to learn more about the timing of tics (sudden, fast movements and sounds that people do and make without meaning to) in people who have multiple tics that have been going on for more than one year. The main questions it aims to answer are: 1. See whether a tic's timing is related to other characteristics of the tic, like how long it has been happening and how well the person can control/stop that tic 2. See whether the timing of a tic can tell us how well the person can control/stop that tic 3. See whether tic treatment changes the timing of tics, and if the timing of a tic has anything to do with how well treatment will work to stop it Participants will meet with a study researcher to learn more about the study, ask questions, and decide whether or not they would like to be involved. If they decide to do the study, they will meet with the researcher 6 times: 1. During the first visit, the study researcher will ask questions about the participant's life, tics, and other psychological symptoms. The researcher will watch the participant's tics for 10 minutes. The participant will do a computer task where they follow instructions to tic or not tic. 2. During the second visit, the study researcher will treat one of the participant's tics. 3. During the third visit, the study researcher will treat another one of the participant's tics. 4. During the fourth visit, the study researcher will treat another one of the participant's tics. 5. During the fifth visit, the study researcher will treat another one of the participant's tics. 6. During the sixth visit, the study researcher will ask questions about the participant's tics and other psychological symptoms. The participant will do a computer task where they follow instructions to tic or not tic.
In clinical practice, it is sometimes difficult to establish whether a patient's tremor is due to Parkinson's disease or essential tremor. The distinction is crucial as the health implications differ significantly between the two conditions. Therefore, the present study aims to develop a diagnostic method based on machine learning techniques to help differentiate whether a patient's tremor is due to one condition or the other. To achieve this, 110 patients with tremor, correctly diagnosed with either Parkinson's disease or essential tremor, will participate. They will undergo two diagnostic tests (tapping test and Archimedean spiral) to capture data that can be processed using machine learning techniques.
The goal of this observational study is to learn about epidemiology, biologic markers, disease subtypes and possible prognostic factors in essential tremor (ET) patients. The main question[s] it aims to answer are: - The prevalence of ET-plus compared to ET in a prospectively collected ET population. - To assess in detail the heterogenous group of ET patients using comprehensive clinical (motor and non-motor scales, questionnaires), imaging [magnetic resonance imaging (MRI), sonography of substantia nigra and cerebral vessels], neurophysiological (tremor analysis, digital spiral drawing) and laboratory markers (sGFAP, sNfL, routine laboratory parameters). - To assess possible non-invasive markers of neurodegeneration in ET patients (optic coherence tomography, alpha-synuclein in olfactory mucosa) Participants will be asked to undergo the above mention evaluation at baseline and at follow-up approx. 5 years later. Researchers will compare the findings within the ET group to independently existing cohorts of healthy controls and/or patients with other movement disorders like Parkinson's disease.
This research is being done to determine the effectiveness of a new treatment, called JOGO, for patients with functional tremor (FT). JOGO is a biofeedback device that has been shown to help patients with several conditions, e.g., chronic pain, migraine, and Parkinson's disease (PD)-related tremor. JOGO provides biofeedback by using wireless adhesive stickers, called surface electromyography, to get information about muscle activity. This information is then used to modify symptoms through a series of training sessions with a physical therapist and individual practice.
This study is designed to demonstrate the safety and tolerability of the Encora Therapeutics Tremor Mitigation Device in subjects with upper limb tremor caused by Essential Tremor.
The investigators propose to advance Vim-FUSA (Ventral Intermediate Nucleus - Focused Ultrasound Ablation) with the support of 3-D tractography, a neuroimaging technique to visually represent nerve tracts within the brain. The investigators hypothesize that 3-D tractography Vim-FUSA will improve the Vim ablation compared to standard Vim-FUSA and prove safe and feasible in the clinical setting. The investigators also hypothesize that intraoperative magnetic resonance (i-MR) monitoring will differentiate ablated tissue from immediate perilesional edema and accurately predict the Vim-FUSA clinical outcomes.
Population Size and Eligible Patients: The investigators aim to recruit 5 to 10 patients with tremors who have previously undergone Ventral Intermedius Deep Brain Stimulation (VIM-DBS) treatment but have experienced early or late loss of benefits. Additionally, the investigators will enroll ten patients with essential tremor who require VIM-DBS surgery. These individuals will undergo bilateral implantation of Boston Scientific Genus Implantable Pulse Generator (IPG) devices, connected to Boston Scientific Cartesia™ 8-contact Directional Leads. Study Design: This study comprises two distinct phases. Phase 1 is a cross-sectional investigation designed to identify the optimal algorithm for patterned stimulation in the VIM region . Phase 2 is a prospective clinical trial focusing on the assessment of safety and efficacy of bilateral VIM-DBS in patients with essential tremor. Objectives: The primary objective in Phase 2 is to evaluate the safety and effectiveness of bilateral VIM-DBS in individuals with essential tremor. In Phase 1, the investigators seek to explore the impact of the Chronos programming software on tremor patients who have experienced early or late loss of benefits.
Essential tremor (ET) is one of the most common movement disorders in adults. The prevalence rate among the elderly over 65 years old is about 4.6%. Tremor usually worsens with age, leading to disability and loss of independence, which has an adverse impact on the quality of life of patients. However, the traditional first-line treatment drugs are neither effective enough nor completely safe for ET patients. Although surgical procedures such as deep brain stimulation (DBS) and thalamotomy can be used to better control unilateral limb tremor, many patients are reluctant to choose surgical treatment because it's invasive. Therefore, there is an urgent need to develop new drugs or non-invasive therapies as a better treatment option for ET. The pathology of the disease is not yet clear, it is generally believed that genetic, aging and environmental factors are related to ET. Hyperactivity of cerebellar function and changes of cerebello-thalamo- cortical (CTC) pathways are currently considered to be the most important pathophysiological mechanisms of ET. Therefore, the cerebellum and cortex may be the best targets for the treatment of tremor. Continuous theta burst stimulation (cTBS) is one of the non-invasive electrophysiological techniques characterized by plexus stimulation, which is similar to low-frequency repetitive transcranial magnetic stimulation (rTMS) but closer to the physiological state of neural activity, and may inhibit the excitability of the stimulated cortex. The stimulation duration is greatly shortened, which is simpler and easier than the low-frequency rTMS of 20-30 minutes. In addition, functional near infrared spectroscopy (fNIRS) is a new non-invasive functional neuroimaging technique. It mainly uses the difference characteristics of oxyhemoglobin and deoxyhemoglobin in brain tissue for near-infrared light absorption at different wavelengths of 600-900nm. The efficacy, safety, and mechanisms involved in non-invasive stimulation therapy for ET patients are still unclear. There are few studies on the treatment of ET with cTBS, and the sample size is small (the largest sample includes only 23 ET patients). Additionally, there was a lack of exploration on the therapeutic mechanism of cTBS for ET patients. Therefore, the investigators conducted a double-blind, randomized, sham-controlled clinical trial to evaluate the safety and efficacy of cTBS in the treatment of ET patients over both cerebellar and cortical area.
This is an investigator initiated study is designed to evaluate the anti-tremor benefits of two marketed medications, methazolamide and acamprosate in subjects with a diagnosis of essential tremor (ET).
