Active clinical trials for "Movement Disorders"

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).

Botulism is a severe form of food poisoning caused by bacteria. This bacteria produces several toxins one of which is botulinum toxin A. This toxin causes the symptoms of food poisoning. Small amounts of botulinum toxin A have been used to treat speech disorders such as stuttering and problems with the muscles of the eyes. The study examines the effectiveness of botulinum toxin as treatment for a variety of movement disorders. The goals of the study are to refine the technique of treatment to provide the best results, to improve the understanding of how botulinum toxin works on movement disorders, and find other conditions that may be treatable with botulinum toxin. In addition, researchers also plan to study the possible use of botulinum toxin F alone and in combination with botulinum toxin A in patients who do not respond to botulinum A toxin treatment.<TAB>...

The purpose of this international study is to evaluate long-term safety and effectiveness of Abbott deep brain stimulation (DBS) systems for all indications, including Parkinson's disease, essential tremor or other disabling tremor and dystonia.

Brief Summary: The goal of the study is to generate a biorepository of longitudinal blood (plasma and serum), cerebral spinal fluid (CSF) and urine linked to genetics and longitudinal clinical information that are made available to the research community. To accomplish these goals, we will enroll 200 Amyotrophic Lateral Sclerosis (ALS) patients and 80 healthy controls from multiple sites, over a 5 year time frame. Additionally, speech measures will be collected on weekly basis at home for all participants. The measurements are performed using a speech recording application installed on their personal device. For a subset of both ALS and healthy participants, we will also collect at-home vital capacity on a weekly basis. It is expected that increased frequency data sampling of these outcome measures will help in better tracking of disease progression. Biofluids and clinical information are collected over a 20-month time frame for each individual enrolled in the research study. ALS participants will be coming to clinic for 5 study visits with a 4-month interval between visits. Healthy participants will be coming for 2 study visits with a 12-month interval between visits. These samples and clinical information will be stored in a de-identified manner and made available for investigators to use in future research studies.

Non-randomized data collection, excepting participants completing the "Implanted DBS Structured Data Collection", who will be randomized to one of two conditions.

The goal of this clinical trial is to the use of VRi specified effects on pain, kinesiophobia, fear of pain, disability, self-efficacy, grip strength and range of motion in motion in people with chronic shoulder pain. The main question[s] it aims to answer are: Can specific immersive virtual reality software decrease movement-evoked pain in patients with chronic shoulder pain compared to non-specific software? Can specific immersive virtual reality software increase shoulder flexion range of motion in patients with chronic shoulder pain compared to non-specific software? Participants will use a specific VRi software compared with non-specific VRi software

Background: - Cerebral palsy (CP) is the most common motor disorder in children. CP often causes crouch gait, an abnormal way of walking. Knee crouch has many causes, so no single device or approach works best for everybody. This study s adjustable brace provides many types of walking assistance. Researchers will evaluate brace options to find the best solution for each participant, and whether one solution works best for the group. Objective: - To evaluate a new brace to improve crouch gait in children with CP. Eligibility: Children 5 17 years old with CP. Healthy volunteers 5 17 years old. Design: All participants will be screened with medical history and physical exam. Healthy volunteers will have 1 visit. They will do motion analysis, EMG, and EEG described below. Participants with CP will have 6 visits. Visit 1: <TAB>1. Motion analysis: Balls will be taped to participants skin. This helps cameras follow their movement. <TAB>2. EMG: Metal discs will be taped to participants skin. They measure electrical muscle activity. <TAB>3. Participants knee movement will be tested. <TAB>4. Participants will walk 50 meters. <TAB>5. Participants legs will be cast to make custom braces. Visit 2: Participants will wear their new braces and have them adjusted. Steps 1 3 will be repeated. EEG: Small metal discs will be placed on the participants scalp. They record brain waves. Participants will have electrical stimulation of their knees and practice extending them. Participants will take several walks with the braces in different settings. Visits 3 5: participants will repeat the walking and some other steps from visit 2. Visit 6 will repeat visit 2.

SLC13A5 deficiency (Citrate Transporter Disorder, EIEE 25) is a rare genetic disorder with neurodevelopmental delays and seizure onset in the first few days of life. This natural history study is designed to address the lack of understanding of disease progression and genotype-phenotype correlation. Additionally it will help in identifying clinical endpoints for use in future clinical trials.

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.
