NCT ID: NCT04769973 Completed - Parkinson Disease Clinical Trials

Treatment Burden in Parkinson's

Start date: June 22, 2021
Phase:
Study type: Observational

Background: People with Parkinson's (PwP) have many symptoms including tremor, stiffness, slow movements, constipation, urinary incontinence and mental health issues. They are often older and have other long-term health conditions. PwP need to do many things to look after their health including manage multiple medications, attend healthcare appointments and lifestyle changes such as improving diet and exercise. The effort of looking after their health and its impact on them is termed 'treatment burden'. Some PwP need help from their family or friends (caregiver) to complete these tasks. Caregivers may also experience treatment burden themselves when caring for someone with Parkinson's. People's ability to manage treatment burden is termed 'capacity' and is influenced by physical, mental, social and economic factors. People are overburdened when the workload of looking after their health exceeds their capacity. This can lead to poor adherence with treatment, poor quality of life and worse health outcomes. Aim: To understand the factors that influence treatment burden and capacity in PwP and caregivers of PwP. Methods: Interviews with PwP and caregivers will identify factors that influence treatment burden and capacity. These factors will be explored further in a national survey for PwP and caregivers through Parkinson's UK. The investigators will form focus groups with PwP, caregivers, voluntary sector representatives, healthcare professionals, policy makers and managers through Parkinson's Excellence Networks to discuss and prioritise recommendations for change. Outcomes: The investigators will disseminate recommendations of ways to reduce treatment burden and improve future experiences of PwP and caregivers.

tDCS of the Primary Motor Cortex to Improve Implicit Motor Sequence Learning in Parkinson's Disease

Start date: October 11, 2020
Phase: N/A
Study type: Interventional

Implicit motor sequence learning (IMSL) is a form of cognitive function that is known to be directly associated with impaired motor function in Parkinson's disease (PD). Research in healthy young participants shows the potential for transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique, over the primary motor cortex (M1) to enhance IMSL. tDCS has direct effects on the underlying cortex, but also induces distant (basal ganglia) network effects - hence its potential value in PD, a prime model of basal ganglia dysfunction. To date, however, only null-effects have been reported in persons with PD. In the present study, the investigators will investigate the potential of tDCS delivered over M1 to enhance IMSL, as measured by the Serial Reaction Time task, in persons with PD. The investigators will determine immediate effects that may occur concurrently with the application of tDCS but also short-term (five minutes post-tDCS) and long-term (one week post-tDCS) consolidation effects, as previous studies suggest that tDCS exerts its beneficial effects on IMSL in a consolidation phase rather than in an acquisition phase. Establishing possible consolidation effects is of a particular interest, as long-term effects are vital for the successful functional rehabilitation of persons with PD.

NCT ID: NCT04300348 Completed - Parkinson Clinical Trials

Improving Walking With Heel-To-Toe Device

Start date: April 15, 2021
Phase: N/A
Study type: Interventional

Introduction: The purpose of this study is to test the efficacy potential of using real-time positive auditory feedback to improve gait pattern in people with Parkinson's Disease (PD). The components of walking are commonly affected in patients with PD. Gait training for PD is usually based on verbal cues from the therapist that are only moderately effective. Based on good principals of gait and neuroplasticity, the Heel-To-Toe (Heel2Toe) sensor was developed to provide real-time auditory feedback during walking training. Methods: A two-group, randomized feasibility trial is planned with repeated measures of gait parameters and walking outcomes. Participants will be assessed at baseline, 3 and 6 months. Outcomes after the 5 training days will be obtained directly from the Hee2Toe device for both groups (with and without auditory feedback). The primary outcome is walking capacity measured by the Six-Minute Walk Test and the Standardized Walking Obstacle Course. Gait parameters will be captured by the Heel2Toe device Expected Contributions: Gait training using the Heel2Toe sensor will be potentially effective for improving walking pattern in people with PD.

Cerebellar rTMS Theta Burst for Dual-task Walking in Parkinson's Disease

Start date: January 1, 2018
Phase: N/A
Study type: Interventional

Objective of the study: To test the efficacy of theta burst cerebellar stimulation on dual task walking in Parkinson's disease using a cross-over design and wearing sensors technology Design: Twenty Parkinson's disease patients with no dementia will be recruited for a cross-over sham-controlled study. Each patient will undergo a sham stimulation or a single session of cerebellar theta burst stimulation with a wash out period of at least 14 days. Each patient will be evaluated before and after stimulation by a battery of gait and movement tests using wearing sensors technology .

AOT-PA
Start date: March 26, 2018
Phase: N/A
Study type: Interventional

The aim of the study is to assess the role of Action Observation Treatment (AOT) and Motor Imagery (MI) in the rehabilitation of Parkinson's disease patients, as compared to a control condition. Main outcome measures will be the results in two functional scales (FIM, UPDRS) and kinematics parameters obtained from gait analysis. Data at two months and six months follow up, respectively, will be also collected.

State-dependent Pathophysiological Oscillations in Parkinson's Disease and Treatment With DBS Using the Medtronic RC+S

Start date: September 1, 2019
Phase: N/A
Study type: Interventional

Primary objectives. The ability of the RC+S to record Local Field Potentials (LFP's) is novel in Deep Brain Stimulation (DBS) technology. The primary goals of this project are to use this function of the RC+S to characterize: 1. The state- and target-dependency of neuronal oscillations in the subthalamic nucleus (STN), internal globus pallidus (GPi) or external globus pallidus (GPe) of patients with PD, 2. How these oscillations are altered by levodopa, 3. The effects of unilateral standard clinical isochronal (e.g. 140 Hz) GPi-, GPe-, and STN-DBS on oscillatory activity and its relationship to the presence and severity of parkinsonian motor signs. These experiments will leverage the capacity to record LFPs from macroelectrodes implanted in either the GPi/GPe or STN using the Medtronic RC+S DBS system. The long-term goal for this project is to develop closed-loop methods for DBS that are state (resting vs. movement) and movement-phase appropriate. Secondary objectives. In addition to establishing the relationship between neural oscillations in the STN, GPi and GPe to clinical and quantitative measures of akinesia, bradykinesia, tremor and rigidity, this project will also examine the relationship of neural oscillations to: 1. Levodopa-resistant motor features such as postural instability and gait (including freezing of gait), 2. Response inhibition and impulse control.

NCT ID: NCT03672266 Recruiting - Alzheimer Disease Clinical Trials

Studies of Brain and Body Interaction

Start date: August 1, 2018
Phase:
Study type: Observational

The goal of this study is to characterize biophysiolgoical signals as a comprehensive profile of the nervous systems in order to understand interactions between the brain and body, while an individual performs naturalistic behaviors (ex. walking, pointing) and while breathing at a slow controlled pace. The investigators aim to study these interactions among a variety of populations, from healthy individuals to those with disorders such as Autism Spectrum Disorder(s), including those who may also have an ADHD (Attention-deficit/hyperactivity disorder) diagnosis, Asperger's Syndrome, Alzheimer's Disease, and/or Fragile X syndrome
