Active clinical trials for "Parkinson Disease"

Remote programming has significant advantages over conventional programming methods on some issues. This research will test the safety of SceneRay remote and wireless DBS programming system.

This study is designed to demonstrate an in-house developed re-attachable stereotactic system that can markedly reduce the overall deep brain stimulation (DBS) procedure time to greatly facilitate subject access to neurosurgical restorative therapies. Subjects will consist exclusively of individuals who have been approved to undergo deep brain stimulation surgery for the treatment of a neurological disorder at Mayo Clinic - Rochester MN. This study is a quantitative comparative, between-subject study enrolling approximately 10 subjects.

This study will investigate the clinical, functional and neurophysiological effects of automated mechanical peripheral stimulation (AMPS) via the Gondola device administered to patients with chronic stroke, cerebral palsy and Parkinson's Disease. Results will be collected using standardized outcome measures and a transcranial magnetic stimulation assessment protocol including electrical stimulation and electromyographic recording.

Parkinson's disease (PD) affects ability of individuals to perform unconscious learned motor tasks, affects quality of life and has been associated with depression. The purpose of this study is to investigate the effect of dance therapy on motor performance, quality of life and depression in PD patients, by comparing certain symptoms between a group of subjects with PD who undergo ballroom dancing classes and a control group of subjects with PD. The investigators will assess mental status, severity of PD, quality of life and depression using rating scales. Subjects will be randomized to intervention and control group. Intervention group will participate in dance therapy for 12 weeks and will be examined at 12 and 20 weeks. Control group will be examined at same time intervals. Classes will follow a curriculum designed by Arthur Murray Dance Studio Staff. The investigators do not anticipate significant risk for participants.

The goal of this clinical trial is to learn about the role of noradrenergic system in the non-motor symptoms of Parkinson's disease. The main objectives it aims to answer are: To explore the association between orthostatic hypertension which is low blood pressure that occurs after going from lying to standing, and several neuropsychiatric and neurocognitive nonmotor features of Parkinson's disease (PD), such as feeling tired or disinterested and depression. To explore the association between central noradrenergic dysfunction, orthostatic hypertension, and nonmotor symptoms of PD by measuring hormonal response to head up tilt-table testing before and after administration of yohimbine. To explore the association between central noradrenergic dysfunction, orthostatic hypertension, and nonmotor symptoms of PD by measuring participants pupils before and after administration of yohimbine Participants will be asked to come onsite for two study visits. Visit one will consist of: Discussing and signing the Informed Consent Form Discussing Medical History and Current Medications Collecting Blood samples Measuring heart rate and blood pressure Mental health screening and neurocognitive questionnaires Pupil test Test to feel vibrations Visit two will consist of : Mental Health questionnaire IV Placement Blood Draws Administration of Yohimbine hydrochloride Head up tilt table Measuring heart rate and blood pressure Answering questions about anxiety, mood, and fatigue using a scale Pupil tests Visit three will be a follow-up call from the Nurse Coordinator to discuss any adverse events.

Sleep benefit (SB) consists of a spontaneous, transient and inconsistent improvement of the mobility occurring on morning awakening in approximately 40% of Parkinson's disease (PD) patients, before taking the first morning dose of dopaminergic drugs. The SB could represent a pathway for the development of new therapeutic strategies for motor symptoms in PD. Being a seemingly unpredictable phenomenon and a great variability daily, inter- and intra-subject, the SB study requires multiple and repeated assessments of mobility for several days. An experimental home setting would be optimal for this purpose in terms of cost-effectiveness and patient acceptability. In addition, since the extent and nature of SB have not been well characterized so far, and the magnitude of its variability is unknown, a reliable assessment method, independent of observers and situation, the SB is a requirement of further research in this area. A recently developed technique combining machine learning algorithms with wireless portable sensors (accelerometers and gyroscopes) and software applications could be particularly promising for characterizing the complexity and multiplicity of SBs in. With this technique, repeated and multiple assessments of mobility can be performed in the homes of patients without the constant presence of a researcher. This approach offers several advantages in terms of cost-effectiveness, feasibility and acceptability of study protocols by patients. It also improves the ecological validity of subjective and objective estimates of mobility in these patients. The investigators chose to conduct this preliminary study on patients with PD rather than on healthy subjects, because SB is a phenomenon that has been described so far only in this population. Investigators also consider that the feasibility of the study will depend mainly on the patients' ability to move and the context of their own illness. SB is a phenomenon induced by sleep. The propensity and timing of sleep depend on the coordinated interaction of the duration of the previous awakening (homeostatic process) and a circadian signal (circadian process). In order to better understand SB, it is necessary to study the reciprocal influences of the circadian and homeostatic process. Investigators have devised a new paradigm to "shift" the circadian process phase around the homeostatic process, maintained under constant conditions, in order to observe the effect of the synchronism or desynchronization of these two processes on the awakening mobility of patients with an MP. This experimental approach was approved by Professor Aleksandar Videnovic (Harvard University School of Medicine, USA), opinion leader on circadian rhythmicity in the MP and scientific collaborator of this study. As a first step, the investigators plan to implement a technology-assisted home-based methodology, to validate it in PD patients and to verify the logistic feasibility of this method-assisted approach in a small group of patients, in order to to be able to apply this paradigm in larger scientific projects.

This study is a single-site, double-blinded, placebo-controlled, randomized clinical trial designed to elucidate mechanism(s) of action for symptomatic benefits observed in Parkinson's disease (PD) patients treating twice daily time-varying caloric vestibular stimulation treatment using a solid-state device. Study participants will self-administer treatments in the home setting over a period of 12 weeks. Changes in cerebral blood flow perfusion, cerebrovascular reactivity and functional connectivity between the pre-treatment baseline and the end of the treatment period will be monitored and will be compared to changes in validated standardized clinical measures of motor and non-motor symptoms in PD. The durability of effects will be evaluated at a post-treatment assessment conducted five weeks after treatment cessation.

Background: Parkinson s disease (PD) is a neurologic disorder that causes slowness, tremor, rigidity, and imbalance. Gait impairment is also common. There are 2 substudies: (1) Physiology of Freezing and Gait; (2) Vibratory Cueing. Healthy participants can join only Substudy 1. Objective: To study gait disorders in PD. Also, to test the effect of specific interventions for gait in people with PD. Eligibility: People ages 18 and older who: Have PD with bilateral symptoms but can walk without a cane or walker Are healthy Design: Participants will be screened in Protocols 93-N-0202 and 01-N-0206. Both substudies include a physical exam and medical history. Substudy 1: Participants will have one 6-hour visit. They must wear a tank tops and shorts with tennis shoes during the visit. They will perform gait tasks. Markers placed on the skin will record movements. They will have an EEG: They will wear an electrode cap to record brain waves. They will wear special glasses to record eye movements. Participants with PD will hold their morning dose of PD drugs. They can choose to be admitted to the hospital the previous evening. Otherwise someone else or a taxi must bring them to the visit. They will first perform the study tasks off their drugs. Then they will take their drugs and repeat them. Substudy 2: Participants will have one 3-hour visit. A small vibratory device will be attached to their ankle. Reflective markers placed on the skin will record movements while they walk: Without the device With the device, but the vibrator off With the device, with the vibrator on With a magnet attached to the ankle

The purpose of this research study is to determine optimum dose of vibration delivered by an experimental device called PDVibe2 required to treat 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.
