Filter by:The goal of this clinical trial is to investigate the feasibility if a remotely administered smartphone app can increase the volume and intensity of physical activity in daily life in patients with isolated Rapid Eye Movement (REM) sleep behaviour disorder over a long period of time (24 months). Participants will be tasked to achieve an incremental increase of daily steps (volume) and amount of minutes exercised at a certain heart rate (intensity) with respect to their own baseline level. Motivation with regards to physical activity will entirely be communicated through the study specific Slow Speed smartphone app. Primary outcomes will be compliance expressed as longitudinal change in digital measures of physical activity (step count) measured using a Fitbit smartwatch. Exploratory outcomes entail retention rate, completeness of remote digital biomarker assessments, digital prodromal motor and non-motor features of PD, blood biomarkers and brain imaging markers. Using these biomarkers, we aim to develop a composite score (prodromal load score) to estimate the total prodromal load. An international exercise study with fellow researchers in the United States and United Kingdom are currently in preparation (Slow-SPEED). Our intention is to analyse overlapping outcomes combined where possible through a meta-analysis plan, to obtain insight on (determinants of) heterogeneity in compliance and possible efficacy across subgroups
The purpose of the study is to determine the effects of a novel, personalized, tactile cueing system on gait automaticity. The researchers hypothesized that step-synchronized tactile cueing will reduce prefrontal cortex activity (improve automaticity) and improve gait variability (as well as gait speed). The researchers predict that improved automaticity with improved gait variability will be associated with increased activation of other than prefrontal cortical areas while walking (i.e., sensory-motor). To determine the effects of cueing, 60 participants with PD from will be randomized into one, of two, cueing interventions: 1) personalized, step-synchronized tactile cueing and 2) tactile cueing at fixed intervals as an active control group. In addition, the researchers will explore the feasibility and potential benefits of independent use of tactile cueing during a week in daily life for a future clinical trial. This project will characterize the cortical correlates of gait automaticity, the changes in gait automaticity with cueing in people with Parkinson's Disease, and how these changes translate to improvement in gait and turning. The long-term goal is to unravel the mechanisms of impaired gait automaticity in Parkinson's Disease.
Parkinson's disease (PD) is a progressive neurological disorder characterized by motor and non-motor symptoms such as rigidity, bradykinesia, resting tremor, cognitive and autonomic dysfunctions, gait and balance difficulties. The impairment of gait, balance and cognitive performances is partially responsive to dopaminergic medications. This emphasizes the importance of non-pharmacological interventions for people with PD (pwPD). Intensive multidisciplinary motor and cognitive rehabilitation has been proposed as a complementary and effective treatment for managing pwPD. Several structural and physiological mechanisms have been suggested to underpin exercise-induced neuroplastic changes in PD, such as enhanced synaptic strength and preservation of dopamine neurons. To date, studies on brain changes induced by motor and cognitive exercises in pwPD have been small-scaled and uncontrolled. Identifying accessible and measurable biomarkers for monitoring the events induced by intensive motor and cognitive rehabilitation program would help in testing the treatment effectiveness and would allow personalization of rehabilitation strategies by predicting patients' responsiveness. Based on validated clinical assessments of intensive multidisciplinary rehabilitation treatment, the project will test the ability of a new set of biomarkers to evaluate rehabilitative outcomes in a cohort of people with PD.
Currently, the Movement Disorders Society (MDS)-UPDRS scale remains the gold standard to document the outcomes in clinical trials for Parkinson's disease (PD). The MDS-UPDRS is far from infallible, as it is based on subjective scoring (using a rather crude ordinal score), while execution of the tests depends on clinical experience. Not surprisingly, the scale is subject to both significant intra- and inter-rater variability that are sufficiently large to mask an underlying true difference between an effective intervention and placebo. Digital biomarkers may be able to overcome the limitations of the MDS-UPDRS, as they continuously collects real-time data, during the patient's day to day activities. In this study the investigators are interested in developing algorithms to track progression of bradykinesia, gait impairment, postural sway, tremor, physical activity, sleep quality, and autonomic dysfunction (the latter being derived from e.g. skin conductance and changes in heart rate variability).
This study is a multicenter randomized double-blind placebo-controlled study. The research content is 1. The improvement effect of Bifidobacterium triple viable capsules（BIFICO） on motor symptoms and constipation and sleep in mild to moderate Parkinson's disease and the safety of the study; 2. the mechanism of the improvement effect of intestinal microecological changes on motor and constipation symptoms in mild to moderate Parkinson's disease.
The aim of this study is to assess the prognosis of paroxysmal kinesigenic choreoathetosis (PKC) in Korean.
Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.
This study is a pilot phased interventional clinical trial . The first stage will recruit 10 patients with antipsychotic induced extrapyramidal symptoms.The patients will take pramipexole for 8 weeks. The inital dose of pramipexole will be 0.375 mg/d, and the adjustment of drug dose will be depended on the the doctor's decision and patients' condition. The second stage was a randomized, rater blindness and Antan controlled clinical study. Researchers will recruit another 40 patients with extrapyramidal symptoms (tradive dyskinesia will be excluded). The patients will randomly be divided into artane group or pramipexole group, and the efficacy and safety condition of pramipexole and artane for different kinds of EPS will be compared. The pramipexole group will have 20 cases, and 20 cases of artane group. The dose of pramipexole group group range from 0.375mg/d to 0.75mg/d dose .The dose of artane range from 2 mg/d to 4 mg/d,.The accurate drug doses can be adjusted by the doctor according to the patients' condition . Researchers will evualate patients' symptom at baseline, after three days' of baseline, 2 weeks,4 weeks, 6 weeks and 8 weeks.

Safety and efficacy of AADC gene transfer in participants with Parkinson's disease.
Deep brain stimulation (DBS) is an established treatment for advanced complicated Parkinson's disease (PD). Several controlled randomized studies have given proof of an advantage for operated patients as compared to medically treated patients in terms of motor outcome, activities of daily living and health status. However these studies have addressed mostly stimulation of the subthalamic nucleus (STN). GPi stimulation has not been compared to best medical treatment (BMT) in a prospective randomized controlled trial in patients with complicated PD who are not good candidates for STN stimulation. The investigators aim assessing GPi-DBS in patients with PD who have contraindications for STN-DBS.
