Active clinical trials for "Parkinson Disease"

Aim of current study was to evaluate the effect of a 2-month comprehensive physiotherapy intervention on different aspects of functional performance. In addition, progression of PD motor symptoms (using standardized clinical tests for the assesment) was of interest

This clinical trial has been designed to study and compare changes in deep brain activity (field potentials) in Parkinson's disease (PD) patients while awake, and during sedation with dexmedetomidine or propofol. The recording is made through a deep brain stimulation (DBS) electrode implanted for PD management. The investigators hypothesize that dexmedetomidine produces fewer changes as compared to propofol, and that those changes are consistent and recognizable when compared to activity in patients not exposed to any sedation. Typification of those changes would in the future allow for patients to undergo this surgery comfortably while not compromising the quality of the recording and of the final clinical outcome. The principal variable analyzed is the signal's power in each of the frequency bands, absolute and relative. The analysis will include usual clinical methods such as rapid Fourier transform (FFT) and window fast Fourier transform (WFFT), wavelet analysis, Gabor, and coherence.

Stimulation of the subthalamic nucleus will have effects on various aspects of neuropsychiatric function.

Neuronal activity in circuits between the basal ganglia (BG) and motor cortical areas is abnormally synchronised and rhythmic. The oscillatory activity prevails at 8-30 Hz in untreated Parkinson's Disease (PD) and its amplitude at both subthalamic and cortical levels inversely correlates with motor impairment. Moreover, these different levels in BG-cortical loops are coherent in this frequency band. The 8-30 Hz activity is suppressed by treatment following treatment with dopaminergic drugs and is partially suppressed prior to and during voluntary movements. An unanswered question is how do BG-cortical loops become so prominently engaged in this oscillatory activity? One possible explanation is that the resonance frequencies of the loops fall in the 8-30 Hz band in the untreated state, so that oscillations in this band are transmitted particularly well. This hypothesis was confirmed in a previous series of experiments.The aim is to determine whether the resonance frequency within BG-cortical loops is correlated to the BG-cortical coherence frequency (with 20 subjets during 24 months).

The objective is to clinically assess the Kinesia HomeView system for automated and remote monitoring of Parkinson's disease (PD) motor symptoms.

A Pharmacokinetic Study of Levodopa and Carbidopa Intestinal Gel in Subjects with Advanced Parkinson's Disease.

Health care benefits and services are received through the Veterans Health Administration (VHA), a component of the United States Department of Veterans Affairs. Over 40,000 Veterans across the Veterans Health Administration are diagnosed with Parkinson's disease (PD), a chronic condition that affects motor function as well as cognition, mood, sleep, and autonomic function. There are not enough subspecialists to manage every Veteran with Parkinson's disease. However, a care model of nurse care managers as catalysts and advocates using needs assessments, evidence-based protocols, and VHA and community access coordination mechanisms to optimize Parkinson's disease care may improve quality of Parkinson's disease care and patient-centered outcomes. If efficacious, this model may be practical to disseminate via an existing VHA national consortium network for Parkinson's disease. Objectives are (1) to implement then analyze via a randomized controlled trial whether a nurse-led, coordinated care management intervention, Care Coordination for Health Promotion and Activities in Parkinson's Disease (CHAPS), compared to usual care will improve adherence to evidence-based practice guidelines and improve health outcomes in Veterans with Parkinson's disease in a region of the southwest United States, and (2) to analyze extent of implementation of the CHAPS intervention and its costs to determine how the intervention can be made sustainable and disseminated throughout Veterans Affairs Medical Centers if efficacious.

The aim of this study is to asses the efficacy and the clinical safety of the transcranial magnetic resonance guided high intensity focused ultrasound system ExAblate 4000, InSightec Ltd. for functional neurosurgery in the treatment of movement disorders. The treatments to be conducted in this study are non-invasive, i.e. without opening the skull, and will create microthalamotomies in specific target areas such as thalamus, subthalamus and pallidum. The data obtained in this study will be used to evaluate the basic safety aspects of this new treatment technology and will serve as a basis for the clinical introduction of MR-guided ultrasound neurosurgery.

This is an open-label, randomised, two-period crossover, single dose study to demonstrate bioequivalence between the extended release 2 mg ropinirole XL tablets manufactured at two different sites in healthy subjects. Dosing will be under fasting conditions and there will be a minimum one week washout between doses. Domperidone will be administered to control dopaminergic side effects. Pharmacokinetic samples will be taken following each dose. Safety assessments will include screening and follow-up vital signs, ECGs and safety laboratory tests. Vital signs and adverse events will be monitored periodically throughout the study.

The ability to perform two or more tasks together is impaired in Parkinson's Disease (PD). Based on pilot work we hypothesize that dual tasking is amenable to training in PD and will not compromise safety. In the proposed study we will therefore collect high level evidence on whether 6 weeks of integrated dual task gait training is more effective than consecutive task practice. The investigators will use a randomized, single blind study design and conduct the same protocols in two academic centers (Katholieke Universiteit Leuven and Radboud Universiteit Nijmegen). The investigators intend to test an experimental condition which consists of focused dual task training in the home using a novel program of personalized cognitive tasks. The aim of dual task training is to teach motor-cognitive task integration and achieve optimal levels of automaticity and functionality. The control arm will receive gait practice and separate cognitive training of the same intensity, but offered consecutively. We will test the hypothesis that dual task training (integration) will have more pronounced effects on complex gait than consecutive task training. Sub-analysis will be conducted on patients with and without freezing of gait. The investigators expect that integrated dual task training may be less effective in patients with freezing, due to the increased fall risk and impaired cognitive profiles. Overall, this project will provide evidence to support future directions for motor learning and innovative rehabilitation targets.
