Active clinical trials for "Parkinson Disease"

This project is a 3-month prospective study assessing the immediate and long-term changes associated with aerobic exercise in quality-of-life measures, nonmotor scores, brief neuropsychological batteries, and local field potentials (LFPs) in those with Parkinson's Disease (PD) who have undergone deep brain stimulation (DBS) surgery for management of their symptoms. In this study, the investigators will assess the feasibility of an aerobic exercise regimen in those with advanced PD and DBS, characterize the immediate and long-term changes in neuronal activity with exercise in PD, and assess the nonmotor impact of exercise in individuals with advanced PD and DBS. The investigators will recruit individuals who are not regular exercisers and develop an individualized 3-month exercise plan with the assistance of physical therapists, using heart rate targets for moderate exercise. Outcomes will be measured at baseline and following 3-months of regular exercise. Field potentials will be noted at baseline, during exercise every 2 weeks, and then a final baseline at the end of 3 months in on-medication and on-stimulation states. This will allow for characterization of field potential changes over time both during exercise as efficiency improves as well as impact on baseline neuronal activity in the resting state. This study is novel in that most aerobic exercise studies target early PD subjects and rarely include those who have undergone DBS surgery. The study will specifically focus on the feasibility of developing an aerobic exercise regimen in those with more advanced disease as well as gathering preliminary data on the impact it will have on motor and nonmotor features in this cohort. In addition to the clinical outcomes, investigators are now able to capture neuronal activity with novel FDA-approved DBS technology, allowing us to non-invasively monitor real-time changes in the basal ganglia in those who have undergone DBS surgery. This study will also aim to characterize baseline neuronal activity in this cohort and monitor for changes that occur during exercise as well as determine if there is a change in baseline neuronal activity as exercise tolerance improves and with consistent, regular aerobic exercise.

This study is a single-site, double-blinded, randomized clinical trial designed to elucidate mechanism(s) of action for symptomatic benefits observed in Parkinson's disease (PD)

In Parkinson's disease (PD), recent work has shown that dopaminergic treatments alter one of the two aspects of impulsivity: they do not alter the propensity to produce "automatic" responses, but deteriorate the ability to inhibit and correct (that is, control) them. In healthy subjects, the investigator's team has also demonstrated that transcranial direct current "cathodal" electrical stimulation (tDCS) of Supplementary Motor Areas decreases the frequency of behavioral errors by improving the ability to "correct" responses. The main objective of this project is to determine whether cathodal tDCS of Supplementary Motor Areas in PD patients under dopaminergic treatment improves the control and correction of errors about to be made and compensates for the deficits induced by the treatment. All participants will perform a reaction time task of choice (Simon's task), with and without ("sham" session) tDCS. The experimental design of this single-center, single-blind, randomized study will be that of 3 parallel groups (treated Parkinson's disease, untreated Parkinson's disease patient, and matched control subjects) with cross-over application of tDCS. All participants will be blind to the operating mode of the tDCS (either functional or in "sham" mode corresponding to a control condition). The order of the sessions (with and without tDCS) will be randomized within each of the 3 groups of subjects. The analysis of errors about to be made but inhibited in time (known as "early errors") will be carried out through electromyographic (surface) recording of muscle activities involved in motor responses. tDCS is expected to improve the ability of treated patients to correct their errors about to be made. This study will thus provide a better understanding of the mechanisms of action control and possibly propose a new therapeutic approach for treatment-induced impulsivity disorders in Parkinson's disease.

The purpose of this research study is to determine how training to step with a metronome on both a treadmill, as well as overground, will influence the way that people with Parkinson disease walk. Using metronomes is commonly used in clinics, but the investigators will be using a combination of slow and fast frequencies to alter the way that people walk. The use of a slower frequency metronome on the treadmill is intended to help participants take larger steps. The use of a faster frequency metronome while walking overground is intended to help participants take faster steps.This will take place over 12 training sessions. Each session will be about an hour. It will include some walking tests and pictures of the brain (using MRI) before and after training.

This is a two-part, double-blind, placebo-controlled, randomized, multicenter Phase 2 clinical trial of JM-010 in patients with Parkinson's Disease.

The purpose of this research study is to determine whether cognitive training will improve cognitive and brain functions in people with Parkinson's Disease (PD) during activities of daily living using cognitive evaluations and magnetic resonance imaging (MRI).

IMPORTANCE: Rehabilitation games have been shown to improve cognitive function among people with various disorders but they have not been explored in home settings for patients with Parkinson's disease. OBJECTIVE: To collect pilot data regarding the therapeutic benefits of self-administered rehabilitation games among patients with Parkinson's disease. METHODS: The investigators will recruit 20 patients with Parkinson's disease into a pilot randomized controlled trial. Patients will be asked to perform two 30-minute sessions per week of training using serious games over a 3-month period in addition to conventional care or undergo only usual care. Patients will be evaluated at baseline, after 12 weeks of treatment, and at 24 weeks. Improvements in cognitive function, depression, quality of life, and mobility will be assessed. RELEVANCE: Identifying whether self-administered rehabilitation games can lead to clinical improvements could have significant implications for the management of the disease.

People with PD have lower cardiopulmonary function than their age matched peers. This decline can further impair a person's ability to participate in exercise and daily activities. Furthermore, the limitations in cardiopulmonary function can have a severe impact on mortality. There is evidence indicating the positive changes IMT can have on cardiopulmonary function in people with PD. Through intensive daily exercise people with PD have shown improvements in maximum inspiratory pressure and maximum expiratory pressure though detraining does occur when the intervention is not continued. The purpose of the proposed study is to determine if improvements in expiratory muscle strength can be maintained with a maintenance inspiratory muscle training program. The hypothesis is that there will be a significant change from baseline at the three and six month follow ups.

The study will explore the viability of an alternative programming strategy in Deep Brain Stimulation (DBS) for patients with Parkinson's Disease (PD).

Gait disorder is a disabling symptom in Parkinson's disease (PD) affecting all patients during the course. Three methods of treadmill training (TT) will be compared to assess additional augmented reality (AR), or additional dual task (DT). AR TT, DT TT, and TT alone applied over 3 weeks at each day will be compared for their impact on falls, walking, freezing and attention for 3 months in a double blinded randomized controlled trial during regular neurorehabilitation.
