The purpose of this project is to provide new knowledge of the relationship between structural and functional changes in cortico-basal ganglia pathways and the severity of motor and non-motor deficits in humans with PD.

The purpose of this study is to test the performance of the wAID-P across 21 sites in the Parkinson Study Group. Each site will perform imaging, clinical scales, diagnosis, and will upload the data to the web-based software tool. The clinical diagnosis will be blinded to the diagnostic algorithm and the imaging diagnosis will be compared to the movement disorders trained neurologist diagnosis.

This study is evaluating the efficacy of MultiStem (drug) on functional outcome in participants with ischemic stroke.

To collect additional real-world safety and effectiveness data for the OCS™ Lung System and to expand the long-term clinical evidence supporting the use of OCS™Lung System in lung transplantation.

This study will evaluate if there is a relationship between bone health, fertility, and metabolism to help develop future treatments for SCI. Both men with and without SCI will be participating in this trial to better understand how bone health, fertility, and metabolism are impacted by an injury to the spinal cord.

We are trying to learn more about how the brain controls movement and how this affects function after stroke. We expect differences in the side of brain damage to result in distinct movements of each arm. We will collect information with standard clinical exams and movements during tasks completed on the Kinereach virtual reality system. We will compare results between people who have and have not had a stroke.

The researchers aim to prove that Qigong practice can result in reduced or relieved neuropathic pain, improved mood, life satisfaction, self-efficacy, enjoyment to move, and community integration; and decreased fear of movement, use of medication or health care services for adults with spinal cord injury.

Freezing of gait is a common problem in people with Parkinson's disease. Episodes of freezing can be overcome when a sensory cue is provided. This study will further develop and study the efficacy of a wireless shoe insole that can monitor walking and provide a cue (acoustic or vibrotactile) when a freezing event is detected. The experiment is designed to further test the ability of the device and algorithm to reliably detect freezing and release the episode with an external cue. This study has the potential to develop a tool that can help reduce the incidence and severity of freezing events in people with Parkinson's disease.

The purpose of this study is to examine a new, experimental treatment for adolescents at risk for suicide attempts called neurofeedback training. In neurofeedback training, you are trying to control your brain function on purpose. In this study, your child will see their brain activity (displayed like a thermometer). He/she will recall positive memories to try to change the levels of their brain activity shown on the visual thermometer inside a scanner.

This is a prospective study aimed at quantifying walking and balance in patients with parkinsonism in the clinical setting in addition to a living environment setting. To accomplish this, we will use a portable motion capture system that is widely used to study biomechanics in humans. Once quantified, we want to test the effects of deep brain stimulation (DBS) frequency in patients who already have DBS systems in place. Thus, our objectives are: 1. Demonstrate that parkinsonism patient-specific kinematics can be used to detect postural instability in the clinic using wearable IMUs. 2. Demonstrate that individualized, home-based postural response curves can detect postural instability and prospectively predict fall risk in patients with parkinsonism.

This is a prospective study aimed at quantifying walking and balance in Parkinson's Disease patients in the clinical setting. To accomplish this, we will use a portable motion capture system that is widely used to study biomechanics in humans. Once quantified, we want to test the effects of deep brain stimulation (DBS) frequency in patients who already have DBS systems in place. Thus, our objectives are: 1. Develop an anonymized database of quantitative postural responses and gait of PD patients. 2. Develop software that can quantify the postural response and gait of PD participants using only standard video camera footage. 3. Test the effectiveness of bilateral high and low frequency STN-DBS on the postural responses and gait of PD patients using the portable motion capture system. 4. We will passively record thalamic LFPs from patients with Medtronic Percept DBS devices while the DBS is OFF, set to low frequency, and set to high frequency.

Almost 300,000 Americans with a spinal cord injury or disorder (SCI/D) suffer from reduced or complete loss of sensory and motor function, which can compromise functional independence and quality of life. The purpose of this study is to find better treatment options for improving sensation and movement after SCI/D.

The purpose of this study will be to investigate the optimization of spinal cord stimulation with ECAPs in patients with spinal cord implants.

This study will investigate neural mechanisms underlying the enhancement of rigidity with an activation maneuver (contralateral voluntary movement such as hand tapping) in people with Parkinson's disease. Rigidity will be measured using a custom robotic manipulandum while neural activity will be assessed using EEG and TMS protocols.

The purpose of this project is to evaluate motor system neuroplasticity and brain structure and function in people with Rapid Eye movement (REM) sleep behavior disorder (RBD) and healthy control participants. Our general hypothesis is that people with idiopathic REM sleep behavior disorder (RBD) will show abnormalities in motor cortical plasticity and alterations in structural and function connectivity that are consistent with changes observed in early Parkinson’s disease (PD).

The purpose of this project is to develop and test a novel non-invasive brain stimulation protocol, using transcranial magnetic stimulation (TMS), that will allow reliable examination of cortical-brainstem motor pathways in humans.

Humanitarian use devices are medical devices approved by the FDA for the treatment of medical conditions affecting fewer than 4,000 patients per year. The FDA reviewed the safety of the device and determined that the probable health benefits outweigh the risks of injury or illness from its use. Effective treatment of symptoms, however, has not been studied in formal clinical trials. Medtronic DBS Therapy delivers electrical stimulation to areas in the brain to help control symptoms of various movement disorders. You may be a candidate for Medtronic DBS Therapy for Dystonia if you have been diagnosed with chronic, intractable (drug refractory) primary dystonia. You or your third party payer (health insurance, Medicare, Medicaid or other) must provide payment for hospital, office and other medical costs related to this therapy.

This study is comparing the benefits and adverse effects of two delivery methods to help patients relax and decrease anxiety during his/her time on mechanical ventilation. This study is not examining the medication but rather the process of how the patient receives the sedation medication: patient controlled or usual care.

Multi-Site Registry study

This research is being completed to examine the cells, brain imaging, and speech in individuals with REM Sleep Behavior Disorder who are taking serotonergic medications such as Citalopram, Escitalopram, Fluoxetine, Fluvoxamine, Paroxetine and Sertraline. The purpose of examining these is to try and see if we can predict signs of Dementia with Lewy bodies (a progressive form of dementia with an increase in decline of thinking, reasoning, and other functions). This may benefit others by enabling us to diagnose Dementia with Lewy Bodies sooner rather than later.

The purpose of the study is to test new biomarkers of amyotrophic lateral sclerosis (ALS) and primary lateral sclerosis (PLS) using MRI scans at 3 tesla (3T). Identifying biomarkers of a disease can lead to a better understanding of the disease as well as improved treatments.

This is a prospective study aimed at quantifying walking and balance in normal pressure hydrocephalus (NPH) patients in the clinical setting. To accomplish this, we will use a portable motion capture system that is widely used to study biomechanics in humans. Once quantified, we want to test the effects of ventriculoperitoneal shunt (VPS) on walking and balance among NPH patients. Thus, our objectives are: Aim 1: We will demonstrate the use of quantitative kinematic data on NPH patients pre-lumbar drain, post-lumbar drain and post-VPS in order to assess the predictive value of CSF removal on gait and balance. Aim 2: We will demonstrate the use of objective, neuropsychological data on NPH patients pre-lumbar drain, post-lumbar drain and post-VPS in order to assess the predictive value of CSF removal on cognition 3. We will demonstrate the use of objective, physical therapy data on NPH patients pre-lumbar drain, post-lumbar drain and post-VPS in order to assess the predictive value of CSF removal on therapeutic intervention in terms of walking and balance measures.

This study will develop a platform for stimulation setting optimization based on power spectral density (PSD) measures. Randomized, controlled trials have demonstrated that stimulation of the anterior nucleus of the thalamus (ANT) suppresses seizures. The central hypothesis tested here will be that PSD measured in the ANT will correlate with seizure frequency and stimulation settings that suppress broadband activity will result in lower seizure rates.
