Filter by: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.
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.
Dystonia is a rare syndrome with varying etiologies. Similarly, tremor conditions refractory to medical management and disabling that they need surgical interventions are rare in our setting. So far there are no randomized controlled trials of pallidotomy for management of dystonia. There is scant literature on the long term efficacy and safety of Pallidotomy, thalamotomy and other such lesioning procedures in the management of movement disorders. The current literature is significantly plagued by publication bias as case reports with successful outcomes are likely to be selectively published in journals or conference abstracts. Lesioning procedures though seem to be effective are often considered to be risky, especially bilateral pallidotomy is not preferred by several centres. However, our center routinely performs simultaneous bilateral pallidotomy. To generate long term data on the efficacy and safety of lesioning procedures in rare diseases like dystonias especially the effect of functional neurosurgery on varying etiologies of the disease, robust registries are required which collect data on all consecutive patients who undergo the procedure.
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.
This is a 6-week exploratory clinical study, designed to test whether treatment with peroneal electrical trans-cutaneous stimulation can have a beneficial effects on symptoms associated with Parkinson's diseases and essential tremor.
This is a multi-centre, single-blind, placebo-controlled trial with an open label follow up. After the baseline assessment, all participants will receive the GyroGlove for two weeks during the open label follow up part of the trial. All gloves will be retrieved and returned to GyroGear after closure of the study.
This is a prospective, multi-center, single arm post-market clinical follow-up study. The present study investigates a product authorized on the European market that will be used per its intended use, and all procedures involved follow the standard of care. This is an observational study to provide clinical evidence in support of DBS effectiveness in the treatment of ET when delivered by the directSTIM DBS system. Twenty-one patients will be enrolled in this study. Subjects selected to participate in the study will be ET patients referred to uni- or bilateral DBS implant who meet the inclusion criteria and none of the exclusion criteria. Primary effectiveness variables will be measured at baseline for the identification of the worst limb (most affected by the disease), then 3 months post-surgery. Safety events will be collected between implant and 3-month visit, to evaluate potential confounding factors. After completing the 3-month visit, subjects will exit the study, and continue to be followed by their physician per usual care. Study will be conducted at minimum 3 centers in Europe.
Essential tremors are no longer a single motor disorder but disorder of movement associated with non-motor symptoms and the aim of this study is to explore the clinical profile of patients with essential tremors including motor and non-motor features and their relationship. and to identify clinical predictors of these features.
