Active clinical trials for "Tremor"

Botulinum toxin is the common treatment of choice for patients with Essential Voice Tremor (EVT), but results are not universally beneficial to all patients. Inconsistent results are noted in the literature and are consistent with the PI's clinical experience. Injection augmentation, a well-established treatment for glottic insufficiency, which is a prominent factor in the clinical presentation of Essential Voice Tremor (EVT), has not been studied. By treating patients at separate times with botulinum toxin and injection augmentation in an unblinded prospective crossover treatment study, we can assess functional outcomes of these two treatments with the population of patients with Essential Voice Tremor (EVT).

We will attempt to establish whether gabapentin as compared with placebo will reduce the severity of tremors caused by the use of antipsychotic medications. Baseline severity of tremor will be measured using both clinical ratings and ratings obtained with an instrument designed to measure tremor, giving more objective evidence of tremor frequency and severity.

The main purpose of this study is to see if transcranial magnetic stimulation (TMS) can be used to help study brain function in healthy people and in those with neurological diseases like essential tremor. This portion of the study is being done to establish the optimal methods for stimulating the brain to measure its responses.

This is a multicenter, open-label, non-controlled, non-randomized, phase 3 clinical study to compare the SPECT findings after a single IV administration of DaTSCAN™ ioflupane (123I) injection for patients with a clinical diagnosis of Parkinsonian syndrome (PS) involving striatal dopaminergic deficit (SDD; specifically, Parkinson's disease [PD] [SDD], multiple system atrophy [MSA] [SDD] or or progressive supranuclear palsy [PSP] [SDD]) as compared with patients with a clinical diagnosis of essential tremor (ET) (no SDD) and age-matched healthy controls.

This is a Phase 2, multicenter, double-blind, placebo-controlled, parallel-group study consisting of a screening period of up to 4 weeks, a 4 week randomized double-blind, dose-titration treatment period, followed by a 1 week safety follow-up period after the last dose of study medication, and a scheduled follow-up safety telephone call one week later.

Recently, there has been increasing interest in performing DBS under general anesthesia, where the stimulated targets are located anatomically (i.e. on MRI) rather than physiologically via microelectrode recordings and intra-operative test stimulation. This technology has been termed "asleep" DBS and is performed with the patient under general anesthesia. Intraoperative imaging is utilized to verify the stereotactic accuracy of DBS electrodes placement at the time of surgery. Because stereotactic accuracy (and surgical safety) is the surgical endpoint, there is no need for the patient to be awake during the procedure.

This is a 2-part clinical trial to evaluate the safety, tolerability, pharmacokinetics, and efficacy of PRAX-114 in participants with essential tremor (ET). Part A is a randomized, double-blind, placebo-controlled, three-period, three-sequence, crossover design where participants will receive a single dose of 10 mg PRAX-114, 20 mg PRAX-114, and matching placebo. Part B is an open-label design where participants from Part A, after washout and confirmation of eligibility may elect to participate in Part B where all participants will receive 10 mg once every morning (QAM) for the first 14 days. Based on investigator judgement of the safety and tolerability, the dose for Days 15 to 28 could be increased to 20 mg QAM.

The clinical utility of deep brain stimulation (DBS) for the treatment of movement disorders such as Parkinson's disease has been well established; however, there is a great disparity in outcomes among DBS recipients due to varied postoperative management, particularly concerning the choosing of an optimal set of programming parameters from the thousands of possible combinations. This study will evaluate the use of motion sensor based assessments to develop a functional map and algorithms to automatically determine a set of programming parameters that maximize symptomatic benefits while minimizing side effects and battery consumption.

This study seeks to compare the use of ultrasound and electrophysiologic techniques to target muscles for the treatment of spasticity and focal dystonia of the limbs. The purpose of this study is to investigate the use of two ways of locating the muscle for botulinum toxin (BoNT) injection for the treatment of focal hand dystonia and upper limb spasticity. Electrophysiologic guidance, using electrical stimulation, and ultrasound are the standard ways of locating muscles during a treatment of BoNT injection.

Aim of the study is to perform a double-blind, crossover, placebo-controlled multicenter study evaluating the efficacy of pramipexole on essential tremor.
