NCT01973543
Safety study of AADC gene transfer (VY-AADC01) in subjects with Parkinson's disease.
NCT03905954
Parkinson's disease leads to loss of employment on average within less than 10 years of disease onset and has been found to be associated with an increased absence from work. This combined with hospitalisation; use of secondary health services; drug usage; and caregivers needing to give up work contributed to the costs associated with the conditions. It has been estimated that early support for working age newly diagnosed would cost the government about 1.5 million Euro in the UK but might lead to a potential cost saving of over half a billion over 5 years. The study will explore the impact of a Parkinson diagnosis on employment. The study will be survey based and will include demographic questions: age, age at diagnosis of PD, educational level, and Nationality; questions pertaining to employment type, history, and reasons for leaving if this happened; and also general health.
NCT04214509
The study aims to identify and systematically characterize Parkinson's patients with mutations in the LRRK2 gene. In about 90% of Parkinson's patients the cause of the disease is unclear. Based on current knowledge, it can be assumed that there are several causes and that the causes may be differ between patients; this makes research into the pathogenesis and possible therapies very difficult. In the case of monogenic Parkinson's diseases, which are due to changes in one gene (e.g. LRRK2), the function of the gene and possible disease mechanisms can be investigated. LRRK2-associated Parkinson's syndrome is clinically indistinguishable from idiopathic Parkinson's disease. It is inherited autosomal dominant, that means if one of the two gene copies is altered, the disease occurs. However, the disease does not occur in every mutation carrier, the penetrance is reduced and the mechanisms for that are still unclear. Ideally, knowledge of what influences penetrance could make it possible to exert targeted influence and prevent the disease. The comprehensive investigation of mechanisms of reduced penetrance but also of the effects of the mutation itself requires systematic investigations of as many affected persons as possible. We therefore aim to identify 4,000 people internationally, of them 1,500 with LRRK2-associated Parkinson's syndrome, 500 with LRRK2-mutations but without Parkinson's symptoms, 500 without mutations and without Parkinson's symptoms, 500 Parkinson patients with mutations in other genes than LRRK2 and 1,000 patients with idiopathic Parkinson's disease from the same populations. The participants will undergo a comprehensive survey on Parkinson's symptoms, concomitant diseases, environmental factors and medication and there is the possibility of more detailed genetic examinations. Participants will be asked to donate samples of blood, urine and household dust.
NCT03675932
Forced cadence cycling (FCC) in which individuals with Parkinson's Disease (PD) pedal with external augmentation at 80-90 revolutions per minute (rpm) has demonstrated significant motor improvement in prior clinical trials. These studies required either a tandem bicycle with second rider or an expensive motorized bicycle, making this therapy inaccessible to most patients. In this pragmatic open-label before and after pilot study investigators examine implementation and effectiveness of (RCC) without tandem or motor augmentation and in a community-based setting. Approximately 30 participants will be recruited to participate in 24 one-hour rapid-cadence spin classes in YMCAs over 8 weeks. Primary outcomes will examine implementation of the intervention and secondary outcomes will examine effectiveness against a historical comparison group.
NCT04264273
This study includes 35 PD patients who underwent submandibular gland needle biopsy. 25 neurologically healthy patients of the local otolaryngological clinic, in whom submandibular gland needle biopsy was performed due to a clinical indication, serve as controls.
NCT04265027
This study evaluates the bioavailability and bioequivalence between two active pharmaceutical ingredient (API) sources of opicapone (OPC) at two different dosage strengths (50 mg and 25 mg) after single and multiple dose administration under fasting conditions in healthy volunteers and assess soluble catechol O methyltransferase (S-COMT) activity in 2 API sources of OPC at two different dosage strengths (50 mg and 25 mg) after single and multiple dose administration under fasting conditions in healthy volunteers
NCT04260581
The investigator aims to assess whether long-term use of amantadine is effective in patients with Parkinson's disease.
NCT03921697
Gait impairments of patients with Parkinson's disease (PD) limit the independence in the daily activities and sensibly increase the risk of falls. New gait analysis methods, based on wearable inertial sensors, have been proposed to track the gait features during treatment and in real-life conditions. Gait training based on auditory cues as Rhythmical Auditory Stimulation (RAS) have preliminarily shown positive effects improving gait velocity, stride length, step cadence of walking in PD. In the current project, the research group will aim to develop a smartphone application (Parkinson App Smartphone Aimed: P.A.St.A.) integrated with sensors and RAS. In a second time, investigators will analyze the spatio-temporal gait parameters obtained by the wearable sensors and the sociodemographic and clinical data, thus generating a big data set, to improve the knowledge about current pharmacological therapies and rehabilitation.
NCT04117737
The aim of this study is to improve knowledge about mechanical gait assistance combined with virtual reality efficiency in gait recovery for Parkinson´s patients. It is hypothesised that 12 sessions of 30 minutes each, over a 4 weeks period, of antigravity treadmill rehabilitation combined with virtual reality treatment is effective for increase gait autonomy in patients with Parkinson's disease.
NCT04238000
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 .
NCT03777501
Previous studies reported that whole body vibration has the potential impact on balance and walking abilities in individuals with Parkinson's disease; however, the inconsistent treatment protocols and different experimental designs lead to inconclusive results. Therefore, the purpose of this study is to investigate the short term and long term effect of whole body vibration on sensorimotor function in individuals with Parkinson's disease. The experimental design will be randomized double-blinded controlled trial. Sixty individuals with idiopathic Parkinson's disease will be randomly assigned to two groups and they are non-random whole body vibration group and conventional therapy group. Each participant will receive the treatment about one hour after the administration of medicine. For non-random whole body vibration group, participants will be required to maintain the erect standing position on the vibratory platform and the frequency and amplitude of vibratory stimuli will be 6Hz and 3mm respectively. Each treatment includes five sessions and each session is composed of one minute whole body vibration and one minute rest. For the conventional therapy group, participants will receive the occupational therapy including dynamic balance training and functional ambulatory training. Each session is 10 minutes in both groups and all participants will receive one and twelve treatment sessions for short-term and long-term effect respectively. Outcome measures include proprioceptive sensitivity threshold of upper limb, position sense test of the knee joint, Unified Parkinson's disease rating scale-motor (UPDRS motor), functional reach, and time up and go test (TUG). Specifically, the investigators want to answer the following four questions: 1) Is there any difference in proprioceptive sensitivity, motor performance and balance before and after treatment in individuals with Parkinson's disease? 2) Is there any difference in short-term and long term effect of whole body vibration in individuals with Parkinson's disease? 3) Is there any difference in treatment effect in individuals with Parkinson's disease in Taiwan?
NCT04222218
Objective of the study: To test the efficacy of theta burst cerebellar stimulation on postural instability in progressive supranuclear palsy using a cross-over design and wearing sensors technology Design: Twenty probable PSP patients with no dementia and still able to walk 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 berg balance tests (BBS), Tinetti scale, PSP-rating scale (PSP-RS), and a battery of gait and movement tests. Static balance was assessed by 30-seconds-trials in semitandem and tandem positions with eyes open and closed using wearing sensors technology.
NCT02495649
The purpose of this study is to evaluate the added value of PET-CT with \[18F\]FDOPA tracer for Assessment of the Myocardial Sympathetic Denervation in patients with or suspected with Parkinson's disease. The investigators expect to see normal values of uptake ratio of \[18F\]FDOPA , in patients with no synuclein underline pathology or previously known cardiovascular disease (no history of high blood pressure or take medications that influence the sympathetic system- exclusion criteria). Low values of uptake ratio is presumed to be found in patients diagnosed with Parkinson's disease or other synuclein pathology. The expected normal ratio of Heart/liver uptake values will be determined from scans of patients refered to \[18F\]FDOPA scan and were found to have normal \[18F\]FDOPA scan of the basal ganglia and no cardiovascular diseases.
NCT04228770
Patients attend pre-assessment clinics (POAC) who require an elective operation and who are having a general anaesthetic. At POAC patients are asked about their health, and past medical conditions to assess their fitness for anaesthetic, a list of medicines taken is documented. Patients can then be given a date for surgery. During their stay in hospital patients will see a pharmacist who confirms what medicines are being taken, and ensures those medicines are prescribed and available during the patients stay. This study is aimed at improving the care of patients who are admitted for elective surgery. The study will review two different interventions made prior to a patient's admission for surgery. One will look at a group of patients taking a high risk medicine and the other a group of patients with a high risk disease. The high risk medicine chosen is warfarin, and the high risk disease is Parkinson's disease. It is known that inappropriate or lack of medicines management in these groups can result in delayed surgery, poorer surgical outcomes and can affect a patient's recovery after surgery. Due to patient numbers and the variability between patients being too great, and a lack of research in this area a controlled trial cannot be performed. This complex intervention will review the interventions made, to understand how and why the interventions change care and what it is specifically within the interventions that are exerting a positive effect to improve care. All elective surgical patients who attend POAC at St James' University Hospital who are either, taking warfarin or who have Parkinson's disease will be seen by a pharmacist. An accurate drug history will be taken and if changes are required to medications these will be resolved at the POAC appointment. Patients will be provided with an individualised perioperative medication plan.
