Active clinical trials for "Parkinson Disease"

Among the impairments associated with Parkinson's disease (PD), gait disturbance is one of the most injurious to the independence in daily living activities and the quality of life of people living with Parkinson's disease (PPD). Despite a considerable amount of research, there is no consensus about the most efficient physiotherapeutic approach to improve gait disturbance. Mental practice (MP) is considered an efficient strategy to improve the motor performance of healthy individuals and people with stroke. However, there is little evidence about its therapeutic results as a tool to improve gait performance in PPD. Thus, the aim of this study is to investigate the effects of mental gait practice associated with physical practice (PP) to improve the gait performance of PPD.

High quality clinical trial and meta-analysis have demonstrated short term, and to a lesser extent, long term benefits in various outcome measures. To achieve positive effects, supervised progressive strength and aerobic endurance training program of 12 weeks was required. Extended progressive strength training improved muscle strength for up to 24 months. While aerobic endurance training would increase walking capacity up to 16 months. 1 There are data suggesting a threshold of intensity of exercise to be reached for the positive effect. This overall body of evidence suggests that regular vigorous exercise should be accorded a central place in the treatment of Parkinson's disease. However, there was no evidence about regular intensive exercise of running in Parkinson's disease. And most of the studies were not randomized with a control group. In this study, the investigators are to investigate the effect of regular vigorous aerobic exercise training of running on motor and non-motor symptoms, and quality-of-life of people with Parkinson's disease.

The aim of study is to analyze the effects of dual task training on balance, gait, cognition and neurotrophic factors in Parkinson's disease.

The investigators aims to assess the effectiveness of behavioral interventions based on sensory cues on freezing of gait in patients with Parkinson's disease after bilateral subthalamic nucleus deep brain stimulation.

A significant number of patients with Parkinson's disease (PD) face motor fluctuations even after repeated titration of the dosing of Levodopa. Dealing with OFF state really becomes problematic for them. Aggravation of bradykinesia, rigidity, tremor and gait difficulty are the common problems in OFF state. Studies are going on drugs like Apomorphine as rescue therapy in OFF state. Recently there are studies with Noninvasive brain stimulation, as an evolving therapeutic option in different neurodegenerative diseases. In this study, the investigators are to evaluate the efficacy of transcranial pulsed current stimulation (tPCS) in the OFF state in PD patients. The investigators will give stimulation via tPCS (active/sham). EEG, Kinematic measurement of upper limb movement via KinArm, Unified Parkinson's Disease Rating Scale (UPDRS) scoring will be done and gait will be assessed via Gait Carpet - pre and post-stimulation. The investigators will evaluate the effectiveness of tPCS as a single modality or in combination with Levodopa in managing OFF state of PD.

The goal of the proposed research is to determine the influence of transcranial direct current stimulation (tDCS) on long-term motor learning, transfer of motor learning, and cortical function in Parkinson's disease (PD). The project comprises a 2 week training study that will involve tDCS applied during two practice motor tasks with behavioral, clinical, and physiological evaluations at baseline as well as 1, 14 and 28 days following the 2 week training and stimulation period. The findings of the proposed studies should have significant clinical significance and applications to comprehensive intervention therapy development in the treatment of PD.

Akinesia is one of the most prominent symptom in Parkinson's Disease (PD) patients. It typically consists in a inability to initiate voluntary movement, and it affects patients' quality of life. This study aims at exploring the influence of Deep Brain Stimulation (DBS) in the quality of motor control, and particularly of voluntary movement initiation, and its neural correlates. They will be evaluated using behavioral and motor tasks together with Transcranial Magnetic Stimulation (TMS) and electrophysiology (EMG and EEG).

Parkinson's disease (PD) is a neurodegenerative and progressive movement disorder, whose population incidence is increasing. It is characterized by motor symptoms such as tremor, stiffness and bradykinesia, and non-motor symptoms, highlighting the executive dysfunction that can be present from the early stages of the disease. These deficits increase the risk of falls and reduce functional independence. Transcranial Direct Current Stimulation (ETCC) can be an attractive rehabilitation option in PD because it is a non-invasive and safe method that can modulate cortical excitability and improve motor and non-motor symptoms. One of the techniques to detect neurophysiological biomarkers associated with changes in the functional health of the brain and the effectiveness of this type of treatment is the analysis of microstates from the electroencephalogram (EEG). So, the objective of the present study is to investigate the effects of different assemblies of multifocal ETCC on the electrical brain activity represented by the EEG microstates and clinical characteristics in patients with PD.

The investigator aims to assess whether long-term use of amantadine is effective in patients with Parkinson's disease.

Introduction: Parkinson's disease (PD) is responsible for several changes in the body, such as balance, gastrointestinal and autonomic disorders and are associated with impairments in the clinical prognosis of these individuals. In this sense, therapies capable of minimizing this impact are extremely important. Osteopathy has become an alternative treatment for individuals with neurological disorders and has been shown to be effective in treating various conditions, including PD. Objective: a) to evaluate the acute effect of visceral manipulation directed to the intestines and visceral plexuses in the autonomic nervous system of PD patients; b) identify the effect of this approach, after four visits, on balance, plantar pressure, gastrointestinal disorders and autonomic nervous system in this population. Materials and Methods: For this randomized clinical trial, 28 adults diagnosed with PD will be recruited. Subjects will be randomized to protocols in two groups: intervention protocol and placebo protocol, where both will consist of 4 visits twice a week. The intervention protocol will consist of osteopathic manipulative techniques and the sham protocol will consist of simulation of therapy, where the therapist will place his hands in the same regions of the intervention protocol, with superficial contact and without therapeutic intention in each region. The outcome measures of the study will consist of Berg balance assessment and plantar pressure, Rome survey on gastrointestinal disorders, and assessment of autonomic modulation by means of heart rate variability analysis. Volunteers and evaluators will be blind to the protocol and not informed of their order. Only the person responsible for the intervention will not be blind to the protocol. Data will be analyzed according to normality (Shapiro-Wilk test), and comparisons of outcomes between the moments (pre and post) will be performed using the T-student test for paired data or Wilcoxon, as normal and for comparisons between protocols. placebo and intervention, Student's T-test for unpaired data or Mann-Whitney test according to normality will be applied. The adopted statistical significance will be fixed at 5%.
