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, we 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.
In nuclear medicine PET examinations, labeled radiopharmaceuticals are possible to enter the putamen and caudate nucleus regions of the striatum in the brain by intravenous injection. The severity of Parkinson's disease is assessed and diagnosed by quantitative analysis of the defect in the image of the radiopharmaceuticals. Clinical studies often use manual selection of regions of interest (ROIs) for quantitative analysis. However, this method causes human error and low reproducibility due to subjective factors, and also considerable time consuming. Therefore, in order to solve the above problems, this research project plans to build an automated quantitative analysis system for PET/MRI images. The quantitative analysis of the PET images is performed automatically by using the putamen and caudate ROI segmented by the MRI images. This automated quantitative analysis system is expected to improve the time-consuming, low reproducibility, and subjectivity problems of traditional manual ROI selection method, and provide a useful tool for the diagnosis of early PD. In the first year, this sub-project is expected to perform MRI T1 and 18F-FDOPA PET scanning of before and after acupuncture-treated PD patients provided by sub-project 3. In the second year, the correlation analysis will be made with the results of tremor test provided by sub-project 1 and that of the 99mTc-TRODAT SPECT image quantification provided by sub-project 4.
The TZ-PD trial will be a 1:1 (active:placebo) randomized, double-blind, placebo-controlled Phase II trial to evaluate the safety and tolerability of terazosin for the treatment of PD.
This study aims to explore the feasibility and effectiveness of mindfulness-based cognitive therapy (MBCT) in reducing anxiety and/or depressive symptoms in people with Parkinson's disease.
This study investigates the initial safety profile of [18F]P17-059 in healthy volunteers including dosimetry determination, and compares regional brain uptake and kinetics of [18F]P17-059 in Parkinson's disease patients with regional brain uptake and kinetics of [18F]P17-059 in healthy volunteers.
The primary purpose of this project is to determine the preliminary effectiveness of protective step training to improve balance and reduce falls in people with Parkinson's disease (PD) and postural disturbances. A secondary purpose is to understand which baseline patient characteristics predict responsiveness to treatment. By informing 1) the effectiveness of a promising rehabilitative intervention, and 2) the selection of the participants that will be most responsive to treatment, these data may enhance clinicians' ability to treat balance disturbances in people with PD. Importantly, protective step training, described in this proposal, can be quickly deployed in the clinic at minimal cost. Therefore, if shown to be effective via this and subsequent trials, this approach can be easily integrated into care, immediately impacting a large number of people with PD.
It has been shown that robot-assisted therapy may be considered an effective and reliable method for the delivery of highly repetitive training useful to boost neuroplasticity. Thus, an early, intensive, repetitive and task oriented training could be an ideal strategy to facilitate relearning of motor function and to improve motor function. The ARMEO-S® is a specific upper limb electromedical device mainly used to reduce spasticity and improve muscle force. To date robotic upper limb training has been applied only in patiebts with brain injury and spinal cord lesions. Aim of the study is to evaluate the efficacy of ARMEO-S in improving upper limb agility in a sample of PD patients, as compared to traditional physiotherapy.
This is an observational study of medical marijuana manufactured and dispensed by Ilera and given as standard treatment for a variety of approved serious medical conditions as defined by individual state law. All patients who are receiving one of the four formulations (Dream, Soothe, Shine and Ease) of medical marijuana will be provided a study flyer and asked to contact the study team via phone or email. Once the study team confirms eligibility, the study team will meet the subject face-to-face most likely at their dispensary (or other mutually agreeable location) and obtain informed consent, and assent when appropriate. Initial baseline demographic information, medical history and medication inventory will be completed. Also, since it is possible that the Investigators will enroll subjects across the region, Investigators anticipate the need to seek consent over the phone for many patients. This will be done via Skype, Go to Meeting, Facetime or similar platforms so that the Investigators can have a face to face interaction with the potential subjects. Regardless of where this discussion takes place (i.e., in person or via the web), all reasonable safeguards to ensure patient privacy will be taken. Patients or their legally authorized representative (LAR) will be given sufficient (i.e., up to several hours/days) to make a decision to participate in this study. Study staff will fax or email the consent form for their signature and no study procedures will begin until the signed consent form is received by the study team. The subjects or their LARs will be instructed on obtaining the blood samples. Blood draws will be completed in the subjects' home after one of their standard doses is taken.
This is a study of subjects with the St. Jude Medical Infinity deep brain stimulation (DBS) system who undergo an MRI imaging procedure. Enrollment may occur before DBS implant, or when an MRI scan is planned in a subject with an existing implant. There will be a follow-up visit one month after the MRI procedure to document any adverse events and verify device functionality.
The purpose of this research study is to test the safety, tolerability, and the effect of vibration (delivered by an experimental device called PDVibe2) on freezing of gait in persons with Parkinson's disease (PD). The PDVibe2 was developed by Resonate Forward, LLC (RF). This PDVibe2 was designed to administer vibration therapy to the wearer to improve gait and balance in persons with PD while wearing the device.
