Filter by:Tremor occurs in up to 55% of dystonia patients, which is known as dystonic tremor syndrome (DTS). Tremor can be present in the body part affected by dystonia (dystonic tremor, DT), or an unaffected body part (tremor associated with dystonia, TAWD). DTS can be treated with botulinum neurotoxin (BoNT) injections, but BoNT is effective in only about 60-70% of patients. It is unknown which patients benefit most from BoNT treatment. We aim to explore the associations between clinical and pathophysiological tremor characteristics and BoNT efficacy. To do so, we will measure clinical, electrophysiological, ultrasonographic and (functional) magnetic resonance imaging ((f)MRI) characteristics before the start of BoNT treatment and measure BoNT efficacy after three three-monthly BoNT sessions.
The aim of this interventional study is to compare the response to alcohol in patients with essential tremor (ET), essential tremor plus (ETplus), dystonic tremor (DT), tremor associated with dystonia (TaD) and tremor in Parkinson´s disease (PD). The main question to be answered is: • Is there a difference in the objective alcohol responsiveness of patients with ET, DT, TaD and PD? Participants will receive either vodka with rum-flavoured orange juice with a target blood alcohol of 0.4 ‰ or a non-alcoholic rum-flavoured orange juice (vice versa on the second study day). Before and 30, 60 an 120 minutes after the study drink the participants will undergo a clinical examination of the tremor and accelerometry will be performed. Researchers will compare alcohol and placebo in a randomized cross over way to see if the effect of alcohol on tremor exceeds the placebo effect.
The goal of this study is to develop a non linear absorber for patients with essential tremor (ET). It 's an extern passive medical device which should improve patients tremor. Investigators will evaluate the impact of this medical device through one clinical scale (Fahn-Tolosa-Marin) and accelerometry record. Investigators focus on motor improvement.
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.
