Filter by:Movement disorders such as dystonia, hypertonia, and spasticity interfere with or prevent voluntary movement. Studies have suggested that using biofeedback to increase awareness of muscle activation can improve motor function in patients with motor deficits. The investigators hypothesize that the daily use of a surface electromyographic (SEMG) biofeedback device for one month will improve motor function in children and young adults with dystonia, hypertonia, and/or spasticity. The SEMG biofeedback device is worn over the muscle(s) the subject has difficulty in controlling and provides vibratory feedback about muscle activation. Groups of children and young adults (ages 3-21), with dystonia, hypertonia, and/or spasticity will be asked to wear a small (approx 1 square inch) sensory feedback device on their affected muscle(s) for 5 hours a day for one month. The device will vibrate and emit a blue light when the muscle is activated. At the start of the experiment, subjects will be tested on the Goal Attainment Scale (GAS), the Pediatric/Adolescent Outcomes Data Collections Instruments (PODCI), and the Barry Albright Dystonia Scale (BAD). For one month, subjects will practice goals without device. After a month, subject will be assessed again and be given device to practice goals for a month. After one month, the subjects will be tested on the outcome measures again and return device.
This is a double-blind, placebo-controlled, Phase IV trial , comparing HMS 90® versus placebo (soy protein) as add-on (adjuvant) therapy in subjects with idiopathic Parkinson's Disease. The principal objective is to evaluate the changes in biomarkers of oxidative stress and,plasma amino acids, as well as improvement of clinical symptoms and brain function
Background: - Deep brain stimulation (DBS) is an approved surgery for certain movement disorders, like Parkinson's disease, that do not respond well to other treatments. DBS uses a battery-powered device called a neurostimulator (like a pacemaker) that is placed under the skin in the chest. It is used to stimulate the areas of the brain that affect movement. Stimulating these areas helps to block the nerve signals that cause abnormal movements. Researchers also want to record the brain function of people with movement disorders during the surgery. Objectives: - To study how DBS surgery affects Parkinson s disease, dystonia, and tremor. - To obtain information on brain and nerve cell function during DBS surgery. Eligibility: - People at least 18 years of age who have movement disorders, like Parkinson's disease, essential tremor, and dystonia. Design: - Researchers will screen patients with physical and neurological exams to decide whether they can have the surgery. Patients will also have a medical history, blood tests, imaging studies, and other tests. Before the surgery, participants will practice movement and memory tests. - During surgery, the stimulator will be placed to provide the right amount of stimulation for the brain. Patients will perform the movement and memory tests that they practiced earlier. - After surgery, participants will recover in the hospital. They will have a followup visit within 4 weeks to turn on and adjust the stimulator. The stimulator has to be programmed and adjusted over weeks to months to find the best settings. - Participants will return for followup visits at 1, 2, and 3 months after surgery. Researchers will test their movement, memory, and general quality of life. Each visit will last about 2 hours.
The purpose of this study is to determine whether 18F-AV-133 PET scans can be used to differentiate subjects with Parkinson's Disease from other movement disorders.
This proposal is focused on developing a reliable, valid, and reproducible imaging techniques and statistical methodology for segregation of various forms of Parkinsonism from healthy adults without Parkinsonism.
Late dyskinetic syndrome with neuroleptics, or tardive dyskinesia, is the appearance of abnormal involuntary movements (AIM) in patients treated with antipsychotics for at least three months. This important public health issue arises for 15-20% of patients treated with neuroleptics, the most prescribed psychotropic drugs in mental disorders in France, and seriously impacts the patients' quality of life. In over 50% of cases, it is irreversible-that is to say that he will persist despite discontinuation of the offending drug. Risk factors have been described: the age and female gender are established, a higher dosage of antipsychotic, a long-term treatment, a psychiatric condition other than schizophrenia are likely risk factors, intermittent treatment, previous acute dyskinesia, neuroleptics or powerful, longer term use of corrective treatments including anticholinergics are still discussed. Apart from preventive treatment, which consists in using antipsychotics as being coerced, support is disappointing: the etiological treatment, which is to stop the offending antipsychotic, is effective only in less than 50% of cases, the syndrome is most often late irreversible. Must still have the possibility to interrupt the treatment, which is usually impossible in the risk of decompensation of the mental illness for which the neuroleptic was prescribed. Remains symptomatic treatment: functional neurosurgery is only for extreme cases, because it is not without risk, in terms of morbidity and mortality. So it's the medication that is most often offered: many drugs have been proposed, a direct result of the multiplicity of neurotransmitter systems implicated. However, in the vast majority of cases, this approach is disappointing not to say ineffective. The only exception is the tetrabenazine, marketed under the name of Xenazine®. Empirically, neurologists specializing in pathology of the movement are almost unanimous: its efficiency is very good, with good tolerance. Some preliminary studies have reinforced this impression. However, their level of evidence remains low and that is why the investigators propose to implement a prospective multicenter clinical trial, double-blind with placebo which will include two groups of 27 patients.
This study is to evaluate long-term safety, tolerability and efficacy for AFQ056 in patients who have completed an AFQ056A study in Parkinson's disease L-dopa induced dyskinesias (PD-LID).
This study will assess the efficacy and safety of modified release AFQ056 in patients that have Parkinson's Disease L-dopa Induced Dyskinesias (PD-LID)
Objective The objective of this pilot study is to characterize the abnormal neuronal firing patterns of basal ganglia neurons and those in the premotor cortex in patients with treatment-resistant movement disorders undergoing deep brain stimulation (DBS) surgery. Study population Fifteen adult patients with treatment-resistant movement disorders who are undergoing deep brain stimulation surgery at Suburban Hospital, Bethesda, Maryland, will be studied. Design This is a physiology study of treatment-resistant movement disorder patients who have been scheduled for implantation of a deep brain stimulation device into the Nucleus accumbens. Prior to surgery, patients will learn a rewarded visual-motor task and undergo magnetoencephalography. The task will be repeated during DBS surgery, with collection of information on electrical activity including single neuronal unit and local field potentials. The task and MEG will be repeated 3-4 months after surgery. The collected data will be analyzed for coherence patterns during rest and rewarded movements. Outcome measures We plan to characterize and quantify the oscillatory activity present in motor circuits of treatment-resistant movement disorder patients during rewarded visually guided movements. We hypothesize that during visually guided movements, neuronal coherence will be significantly increased relative to resting periods. Thus, by better understanding the alteration in oscillatory patterns in these patients, we hope to develop better DBS stimulation paradigms in order to better treat this disease in the future.
The purpose of this project is to determine the equivalency of extrapyramidal symptoms (EPS) and tardive dyskinesia (TD) examinations conducted via live two-way video versus live examinations completed in-person
