Filter by:Vibration applied to the skin has been anecdotally reported to potentially improve motor control in patients with movement disorders including Parkinson's disease, however few devices have been studied formally. In this study, the investigators will test the effect of skin surface vibration applied non-invasively to patients with movement disorders to determine if there are any beneficial effects on common tasks of motor control and/or abnormal motor symptoms in patients with Parkinson's disease (PD), essential tremor (ET), and dystonia.
This multi-center, randomized, double-blinded, placebo-controlled, dose-range-finding clinical trial (with an optional Extension comprised of an Extension Double-blind (DB) Lead in Period followed by an Extension Open-label (OL) Period) that will assess the efficacy, safety, and tolerability of PRAX 944 in participants aged 18 years or older who have a diagnosis of Essential Tremor (ET) and have had symptoms for at least 3 years.
This is a 2-part clinical trial to evaluate the efficacy, safety, and tolerability of 40 and 120 mg oral PRAX-944 compared to placebo in the treatment of adults with essential tremor. Part A is designed to study the dose titration from 20 to 40 mg every morning (QAM) (ie, 2 weeks with 7 days at each dose level). Part B is designed to study the dose titration from 20 to up to 120 mg QAM with at least 14 days of dosing at the highest tolerated dose for each participant. Blood levels of PRAX-944 will also be measured throughout the trial and pharmacokinetics will be evaluated.
Demonstrate safety and efficacy of TAPS delivered by a Cala device as a treatment for action tremor in subjects with Parkinson's disease hand tremor
The main objective of this study is to evaluate the efficacy, safety, and tolerability of NBI-827104 in adults with essential tremor.
The purpose of this study is to determine whether a single treatment with administration of NT 201 (botulinum toxin) is superior to placebo (no medicine) for one-sided treatment of essential tremor in the arm (Unilateral Period). Participants will be assigned to the treatment groups by chance and neither the participants nor the research staff who interact with them will know the allocation. The following treatment cycle will investigate the safety and tolerability of two-sided treatment with NT 201 (botulinum toxin) (Open Label Bliaterial Period). All participants will receive NT 201 treatment.
This study will be a single-centre, prospective, single-arm, open-label, 12-week pilot trial assessing the safety and preliminary efficacy of a second MR-guided focused ultrasound (MRgFUS) thalamotomy on the naïve brain hemisphere after 48 weeks or more of the first MRgFUS thalamotomy in patients with medication-refractory ET. This study will be conducted at the Focused Ultrasound Centre of Excellence at Sunnybrook Health Sciences Centre/University of Toronto.
The purpose of this study is to evaluate the accuracy of the Neurolocate recording system of the neurosurgical robot Neuromate, marketed by Renishaw, in order to optimize surgical procedures, costs and patient comfort.
Pathophysiology of tremor-modulating mechanisms of propranolol and primidone in essential tremor (ET) will be studied using accelerometry with electromyography (EMG), transcranial magnetic stimulation (TMS), and eyeblink conditioning paradigm (EBCC). TMS is a well-established experimental method for studying the effects of drugs on motor cortex excitability. EBCC is a learning paradigm that can be used for studying cerebellar dysfunction since only brainstem and cerebellar functions seem to be needed for this paradigm. The investigators will use TMS to study the mechanisms of primidone and propranolol action in ET, EBCC paradigm to evaluate cerebellar dysfunction in ET patients and to show whether cerebellar dysfunction influences the effectiveness of propranolol and primidone. The investigators will clinically assess patients using The Essential Tremor Rating Assessment Scale (TETRAS) and the Scale for the Assessment and Rating of Ataxia (SARA) scales. Patients with ET will be studied prior to treatment with propranolol or primidone and re-tested 3-6 months after treatment initiation. On each visit, the investigators will clinically assess the patients and perform accelerometry, TMS measurements, and the eyeblink classical conditioning (EBCC) paradigm. The investigators hypothesize that in ET patients, baseline electrophysiological parameters will differ between responders and non-responders to propranolol and primidone and that propranolol and primidone will cause a different pattern of change in electrophysiological parameters among responders. It is hypothesized that cerebellar dysfunction will negatively correlate with patients' response to treatment.
The purpose of this investigation is to determine the optimal DRT/VIM target location and its safety margins based on MR-SISET imaging features by comparing with postoperative lesions and clinical outcomes in patients with tremor who will undergo the MRgFUS tremor therapy.
